The Vauxhall Cascada Is Dead, Is The Buick Version Far Behind?

Clearly four-seat convertibles aren't as popular as SUVs.

GM's Opel and Vauxhall brands were purchased last year by the PSA Group, which includes the French Peugeot and Citroen brands. So far, the sale hasn't affected the Opel or Vauxhall model lineups, nor has it impacted the few Buick models that are built on Opel/Vauxhall platforms. Now we may be seeing the first repercussions of the PSA sale, as Autocar reports that the Vauxhall Cascada is now dead after only a few short model years.

Vauxhall Cascada production had already ended a while ago, but the car continued to be sold until supplies ran out. Vauxhall only sold 200 Cascadas through all of 2017, and only shifted 850 units in the car's best sales year. The Cascada will continue to be sold in other parts of Europe as an Opel, and Buick hasn't given any indication of cancelling the car in the US. According to GM Authority, Buick has only sold 2,292 Cascadas through the first half of 2018. If this pace continues, it would be an 18% decrease over 2017 when the company sold 5,595 units.

During its first model year in 2016, the Buick Cascada had it best sales year with 7,153 units, which isn't massive. The Cascada is clearly a niche model for Buick, and GM doesn't really market it alongside other models in the lineup. We wouldn't be surprised if the Cascada is discontinued after 2018, or 2019 to sell off excess units.

Instructions) provides an overview of each diagnostic category.



DTC Descriptor



DTC B1440 00



- Power Mode Master Input Circuits Mismatch



Diagnostic Fault Information



Circuit/System Description



This vehicles power mode master (PMM) is the body control module (BCM). The ignition switch is a low current switch with multiple discrete



ignition switch signals to the PMM for determination of the power mode. The PMM receives the ignition switch signals, and additionally a reference



voltage signal from the BCM, through the ignition switch, and back to the BCM. There are redundancies within the PMM system that can allow



operation of certain subsystems when there are faults in the ignition switch circuits. Other information such as serial data input from other modules



and DTCs is also used to determine what power mode signals and information is transmitted by the PMM. The BCM logic uses all this information



to identify the operators desired power mode and activate specific discrete signals, and serial data messages for the operation of many different



subsystems as necessary. Other modules which have switched voltage inputs may operate in a default mode if the PMM serial data message does not



match what the individual module can see from its own connections.



The PMM will activate relays and other direct outputs of the PMM as needed according to the calculated power mode. Several relays controlled by



the BCM are switched ignition voltage outputs the are pass through circuits within the BCM directly from the ignition switch. If these circuits short



to ground, the fuse to the ignition switch will open.



Conditions for Running the DTC



Ignition switch is in the RUN position.



Conditions for Setting the DTC



* BCM senses an open or short to voltage on the off/run/crank voltage circuit when both ignition accessory/run and ignition run/crank



parameters are active.



* BCM senses an open on the battery positive voltage circuit (to the ignition switch) while engine is running. An open on the battery voltage



circuit can be caused by a short to ground on any of the following circuits:



- Battery positive voltage



- Accessory voltage



- Run/crank ignition 1 voltage



- Off/run/crank voltage



Action Taken When the DTC Sets



* The BCM operates in a fail-safe power mode dependent on the last valid power mode detected and the state of the engine run flag data on the



GMLAN serial data communications circuits.



* The other modules on the vehicle operate in a fail-safe power mode dependent on the last valid power mode transmitted by the BCM and the



state of the engine run flag on the GMLAN serial data communications circuits.



* The vehicle may not start.



Conditions for Clearing the DTC



* A current DTC clears when the malfunction is no longer present.



* A history DTC clears when the module ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.



Diagnostic Aids



* A short to ground in the accessory wakeup serial data circuit will cause an open fuse to the ignition switch. DTC U1814 should be current.



* A short to ground in the run/crank ignition 1 voltage circuit of the run crank relay will cause an open fuse to the ignition switch. DTC B1428



should be current.



* The power modes and controls are determined using BCM logic. Comparing the Body Control Module Power Mode data display parameters



listed in Circuit/System Verification will determine if there is a power mode fault.

LaCrosse: Buick Revitalized

The 2010 Buick LaCrosse is the breath of fresh air Buick has been waiting for, especially after the massive GM bailout in the last couple of years. The well received sedan is outfitted with GM's direct-injected Ecotec 2.4-liter four-cylinder with 182 hp, something that will surely be noticed by even casual drivers. With better fuel economy, the LaCrosse goes from zero to 60 in just nine seconds, but keep in mind that the four cylinder LaCrosse isn't a sports sedan.

The LaCrosse's fine build gives the driver a smooth, quiet, and comfortable ride and is ideal for those of us who prefer to save the gas and take their time getting there. Buick officials point out the surge in popularity of fuel efficient vehicles like the LaCrosse, especially after gas prices went through the roof.

Buick Enspire Electric SUV Concept To Debut In Beijing

Buick will be lifting the wraps off its new all-electric SUV concept next week on April 17.

With the New York Auto Show now a distant memory, Beijing is the next venue on the annual show calendar. The Beijing Auto Show will open its doors later this month, and already automakers are teasing new models and concepts we can expect to see at the event. Ahead of the show, Buick has teased a mysterious new concept. Called the Enspire, the American automaker has confirmed the concept will be an all-electric concept SUV. No surprises there, then.

Buick has released a teaser image of the concept revealing the tailgate with a raked rear windshield and sleek taillights, but technical specifications have yet to be revealed. Buick describes the Enspire as “an exploration of design and new technologies” that “leverages GM’s global resources” as an “application of future electric smart mobility.” No other information has been released at this point, but we won’t have to wait too long to find out more. Buick will be lifting the wraps off the Enspire concept at a dedicated Buick Brand Night event on April 17th in Wuzhen, Zhejiang, before showcasing the all-electric SUV concept at Auto China 2018, better known as the Beijing Auto Show, later this month.

It’s not clear if the Enspire concept will spawn a production version in the US, but it will most likely go on sale in China first. Why? Because Buick sells more vehicles in China than anywhere else in the world. Case in point: out of the 1.4 million vehicles Buick shipped last year, a staggering 1.2 million were sold in China alone. In contrast, Buick sold less than 220,000 vehicles in its US homeland. There is still hope the Enspire could make it Stateside, however. After all, the Envision crossover is built in China but was eventually brought over to the US in 2016. Buick also currently offers the compact Encore and the full-size Enclave in the US, so the Enspire could potentially slot neatly in between them.

Which French Automaker Will Return To The US First?

Place your bets.

If you've been paying any attention to the news, you've probably heard about French automaker PSA Group and its planned return to the US market. PSA Group is responsible for building Peugeot, DS, and Citroen vehicles as well as Opel and Vauxhall vehicles after purchasing the brands from General Motors. Recently, PSA has been contemplating a return to the US market, and now Automotive News reports that the French automaker is currently on track to sell cars once again in the US.

Company CEO Carlos Tavares says "We are on time with our push to America. First, we are now implementing a certain number of operations for our mobility services. For our Free2Move mobility service plan, which is now ongoing, it is important for us to get closer to US consumers so that we can understand their behaviors and expectations so that we can come up with solutions that will make them happy."

After implementing the mobility service, PSA plans to sell cars in the US by 2026. Unfortunately, PSA still doesn't know which of its brands to bring to the US. DS makes some sense because the brand sells multiple crossovers and hybrid vehicles, though Opel and Vauxhall could be interesting choices as well. The US already receives the Opel/Vauxhall Insignia in the form of the Buick Regal, so it could be an easy transition for PSA.

Peugeot last pulled out of the US market in 1991, so the company wants to make sure it is back for good this time. This will involve a long-term investment in a dealership network and careful planning. We expect electrification to play a huge role in PSA's US lineup when it finally arrives. The new DS 7 Crossback E-Tense is a stylish plug-in hybrid SUV with 300 horsepower and a 31-mile electric range - exactly the type of vehicle US consumers would love. We are still about seven years away from seeing French vehicles on US roads, though we may soon start to hear some announcements about what cars will be coming in the next few years.

Get Ready For A Hyper-SUV Based On The Bugatti Chiron

Because the world apparently needs more hyper-SUVs.

For as long as anyone can remember Molsheim has been a one car stable, but in an age where even hypercar makers like Bugatti are part of big corporate conglomerates and beholden to mundane obligations like shareholders and fuel economy, that opinion may be changing.

Despite teasing us over the years with more family-friendly concept cars like the EB112 and Galibier sedans, Bugatti has never actually pulled the trigger on a second model. However, now that the man responsible for the Lamborghini Urus, Stephan Winkelmann, is in charge it looks like the brand could be ready to do more.

"For me the brand is ready to do more than one model," he told CarAdvice, "but we will have to see if we can find [the investment], this is something we are still waiting for because the [Volkswagen] Group has significant investments in projects like autonomous driving and electric cars."

"It's clear that if we do something different from a super sports car, something different from the Chiron, then it would not be enough just to be in love with one type of car," Winkelmann continued.

While we cited Bugatti as one of the few brands that refuse to build an SUV, with a new man at the helm the carmaker could be set to change course.

"We would look very different at every body style and also regional demand, see what is going up and what is going down, and also in terms of pricing. We would not put our money into something which is fading." Which is basically a very long-winded way of saying a super sedan probably isn’t the smartest idea given today’s sales climate. It’s not hard to read between the lines, especially given his push to create the Urus at Lamborghini. On the other hand, I could get behind the idea of a lifted Divo done up 911 Safari style...

Even so, Bugatti produces on average just 70 cars a year, so whatever it ends up doing will most certainly still be released in extremely limited quantities.

- Front Wiper Relay Drive Circuit Short to Ground



Diagnostic Fault Information



Circuit/System Description



The body control module (BCM) monitors the control circuit of the wiper relay. The voltage level should be low while the wiper relay is



de-energized and near system voltage when the relay is energized. After the BCM receives a low, intermittent, or mist signal from the wiper/washer



switch, it responds by applying battery voltage through the wiper relay control circuit to the coil side of the relay, energizing the WIPER Relay.



Ground is supplied at all times to the coil side of the WIPER relay.



Conditions for Running the DTC



This DTC can set only when the output is actively being requested by the BCM.

Cars That Sold Out Before They Went On Sale

Some before we even knew what they looked like.

There’s only one thing that can ruin the thrill of watching a hot new machine being unveiled with mouthwatering specs, nearly a thousand horsepower, or a 0-60 mph time of fewer than three seconds, maybe even a top speed north of 250 mph. So many times, an amazing piece of machinery is unveiled, only for a manufacturer to announce, “we’ll be building X amount, and they’re all sold out.” Here at CarBuzz, we hate that line – it’s like giving a wrongly imprisoned captive hope of release, only to tell him he can’t have his freedom. To prove what we’re talking about, here are ten times amazing cars were unveiled, only for them to be sold out before they were even produced or officially went on sale.

Bugatti Divo

Named after French racing driver, Albert Divo, the Bugatti Divo is what happens when the Bugatti Chiron gets remodeled for pure track-driving ecstasy. With reworked aerodynamic bodywork and 1,479 imperial horsepower on offer from the 8.0-liter quad-turbo W16, the Divo is a fierce track machine that any gearhead would love to get their hands on. And yet, with just 40 units set for production, when the car was unveiled this year at Pebble Beach, every single one was already spoken for, sold by special invitation to previous Bugatti owners for $5.8 million.

Porsche 911 R

The Porsche 911 GT3 RS is the stuff dreams are made of, widely lauded as one of the best driver’s cars around. But the GT3 RS had one giant flaw for the mass of internet enthusiasts that pined over it – it was only available with Porsche’s PDK dual-clutch transmission, no manual shifter at all. The limited edition Porsche 911 R changed all that, offering 500 horsepower of naturally aspirated 911 GT3 RS power, with reduced weight, subtler styling, and crucially, a gearbox that required the driver to do the shifting manually, with a clutch pedal! 991 of them were built – correlating with the 991 series code – and by the time the 911 R was unveiled at the Geneva Motor Show in 2016, all units had already been sold to existing Porsche owners.

McLaren Speedtail

For those who grew up in the ‘90s, the McLaren F1 was likely one of the posters adorning your walls; the world’s fastest car, with a gold-lined engine bay, a BMW engine, and 3 seats with the driver sitting centrally. So imagine our sheer joy when in 2016, 17 years after the F1 went out of production, McLaren announced a successor to the F1, set to be the fastest McLaren ever. Unveiled just last week, the McLaren Speedtail lives up to the hype the announcement created, with 3 seats, a 1,035 horsepower hybrid drivetrain, and a top speed of 250 mph. In keeping with the F1-heritage, only 106 Speedtails will be produced. And all units were immediately snapped up when McLaren first announced the Speedtail in 2016 – most of them to the same people who bought the original 106 F1s in the 1990s.

LaFerrari Aperta

The LaFerrari was the Italian marque’s successor to the Enzo, and also the very first hybrid to emerge – though many more are in the cards. But when the Aperta, the convertible version of the LaFerrari was unveiled, it had already been sold to a batch of select clients, all of whom had received personal invitations to purchase a LaFerrari Aperta.

200 were built for sale to clients, though there was one additional model built to be auctioned for fundraising in support of the Save the Children charity foundation, which sold for $10,000,000. A hybridized V12 with 950 hp, rear-wheel drive, and an open top to enjoy the V12 noise – and us mere mortals have never even gifted the opportunity to try and buy one.

Lamborghini Centenario

To celebrate the 100th birthday of the company’s founder, Lamborghini unveiled the Centenario at the 2016 Geneva Motor Show. It made use of an uprated 759-hp V12 from the Aventador upon which it was based, and featured bespoke styling. Later that year, at Pebble Beach, the Centenario Roadster was unveiled. Just 20 of each body style were produced, making 40 in total, and yet at the time each was unveiled, every single one of them was spoken for, making it yet another piece of forbidden fruit from Lamborghini.

Aston Martin Valkyrie

Previously known as the AM-RB001, the now-named Valkyrie is the hypercar collaboration between Aston Martin and Red Bull Racing, designed by Formula 1 genius, Adrian Newey. The road car is set to be one of the fastest ever, with Aston Martin claiming Formula 1 racecar-like performance – something to rival the Mercedes-AMG One. Powered by a 6.5-liter Cosworth V12 with a Rimac-built KERS hybrid system, combined outputs of the yet to be produced hypercar are 1,130hp. Aerodynamically optimized, the Valkyrie is said to be capable of generating 4,000 lbs of downforce. Only 150 road-going units will be produced, priced at $3.2-million apiece, but all of the build slots have been allocated.

Mercedes-AMG One

The Valkyrie’s chief rival comes from Mercedes-AMG, using its own Formula 1 involvement to create the (Project) One. Making use of a hybrid drivetrain, including a road-legalized version of the 1.6-liter turbocharged V6 from the W07 Formula 1 car, power outputs are expected to reach a maximum of 1,231 hp channeled to all four corners. A planned production run of 275 units is expected between 2020 and 2021, but now, two years before production even begins, they’re already sold out for a price of $2.72 million each. The demand was so high that Mercedes-AMG received orders for four times the production volume, but in an effort to maintain exclusivity, it refused to increase production volumes.

McLaren Senna

While it’s nowhere near as bespoke as the Speedtail – the McLaren Senna is no less special, with a design epitomizing the ‘form-follows-function’ principle. It’s designed to be the best of the best on any race track, while still remaining road legal. Based loosely around the 720S, the Senna is powered by a 789-hp version of the 4.0-liter twin-turbo V8, driving the rear wheels and aided by a trick suspension and huge amounts of downforce. Named after legendary Formula 1 driver, Ayrton Senna, just 500 units are being produced, though at the time of unveiling all had already been pre-sold, with the last build-slot auctioned off at a private McLaren customer event. 500 special cars, all sold before we even knew it existed.

Ford GT

Ford announced the new Ford GT ahead of the 50th anniversary of its famous Le Mans victory, announcing that it would race once again – something it did rather successfully. But for the production models, you couldn’t just buy one from the showroom. You had to apply to Ford and go through a vetting process, before being awarded a build slot in the original production run of 100 vehicles promised in 2015. Ford has since expanded the production run by another 350 units, though those orders are sure to be sealed long before you get the chance to even think of applying. With 647 hp from its mid-mounted twin-turbo V6, the all-American supercar’s sold-out status deserves to be crowned a national disaster.

TVR Griffith Launch Edition

British supercar-brand, TVR, has flirted with death for the last two decades. But late last year, a new model was unveiled to spark the revival of the special brand. Using an iStream carbon fiber chassis and a Cosworth-tuned Ford Coyote V8, the rear-wheel-drive supercar generates 480 hp and claims the 0-60 mph victory in less than 4 seconds. The first allocation of the as of yet unproduced Griffith, the 500 unit Launch Edition, sold out within six weeks of its announcement, months before it was ever unveiled.

European Plans Spell The End Of The Buick Cascada

Now under French ownership, Opel will stop producing the Cascada after 2019.

The Buick Cascada may not be long for this world, thanks to a decision not from General Motors, but from a French-owned German automaker.

GM recently sold its Opel and Vauxhall brands to the PSA group, which continues to furnish some models to be sold as Buicks in North America. But Opel has revealed product plans for the coming years – and they don't include the Cascada. In order to “focus on high volume segments,” the German unit announced, “the Opel Adam, Karl, and Cascada will not be replaced after the end of their life cycles, but will remain on sale until the end of 2019.”

The statement refers to two small hatchbacks it currently produces, along with the Cascada that's rebadged as a Buick on this side of the Atlantic.

Buick spokesman Stuart Fowle declined to comment on the convertible's future in America. “The Cascada continues to bring in a higher percentage of new customers to Buick than any other model,” he pointed out. That may be neither here nor there, but we wouldn't be the least bit surprised to see Buick join its former European colleagues in phasing out the Cascada, rather than replace it with a new model after Opel discontinues production.

Over the first three quarters of this year, GM reports having sold 1,101 Cascadas in the United States out of the 45,911 Buicks it moved in total. That makes it by far the brand's slowest-selling model, amounting to barely half the deliveries of the next-slowest LaCrosse, and less than a twentieth of the most popular Encore. Those numbers, in fact, place the Cascada as the slowest-selling vehicle GM offers in North America, and barely a drop in the bucket of the nearly 700,000 vehicles it has sold in the US so far this year.

The Cascada's slow sales reflect a general trend away from cossetting four-seat cabriolets, and arrived on the market in 2015 as the segment had already plummeted. Erstwhile rivals like the Lexus IS-C, Infiniti G37 Convertible, Volvo C70, and Volkwagen Eos have all been discontinued amidst flagging sales. Their departure have left the Ford Mustang and Chevy Camaro (on which GM may be forced to rely) to anchor the lower (though more exciting) end of the declining market for four-seat convertibles, and Audi, BMW, and Mercedes-Benz to dominate the higher end with models like the A5, 4 Series, and C-Class cabrios.

Buick's Avenir Sub-Brand Is Already A Huge Hit

Turns out buyers love spending more for their Buick.

We hoped Buick would put the stunning Avenir Concept into production, but the American automaker decided instead to use the name to create a high-trim luxury sub-brand in the vein of GMC's Denali line. So far, the Avenir trim has been applied to the LaCrosse sedan and Enclave SUV, and we'll give you three guesses which one is selling better so far. According to Automotive News, one in every four Enclaves sold is an Avenir, and dealers are struggling to keep up with demand.

Sales of the Enclave increased by 15% in the first half of 2018, and the average transaction price went up by around $5,000. This is a win-win for Buick, as shoppers are buying more Enclave models and at a higher price. After only a year of sales, Buick has already invested to increase Avenir trim production to keep up with demand. Jace Stokes, manager of product marketing for the Enclave, says the company is now planning for "Avenir 2.0," with even more differentiation in terms of styling and technology.

The Avenir costs $13,500 more than the base model Enclave, and is the only trim level with the optional $2,095 technology package, which includes adaptive cruise control and a real-time dampening suspension. Buick says that 80% of Enclave Avenir models are sold with the technology package, which amounts to even more profit for the company. The sky is the limit for the Avenir sub-brand. Given that Buick has already affixed the name to the LaCrosse sedan as well, we could eventually see an Avenir version of every model in the lineup.

Bugatti Could Be Working On A Hardcore Chiron SS

Superleggera and Apera versions of the Chiron are also allegedly in the works.

Bugatti unveiled the Divo hypercar as the ultimate version of the Chiron, combining striking styling harking back to the company’s coachbuilding days along with sharper handling. According to a report by Automobile, the Divo could be the first in a series of limited-edition Chiron-based cars to help boost sales.

Citing unnamed insiders, the publications claims Bugatti is working on Superleggera, SS and Aperta versions of the Chiron. As the name implies, the Chiron Superleggera would be extremely lightweight, more aerodynamically efficient and have a limited production run.

The Chiron SS, on the other hand, would be more hardcore and track-focused. Going by the Veyron SS, we're expecting it to feature a more powerful version of Bugatti’s quad-turbocharged W16 engine and lighter components. The Aperta would follow in the vein of the Veyron Grand Sport Vitesse that was introduced towards the end of the Veyron’s lifecycle and feature a removable hardtop roof.

Intriguingly, Automobile also claims Bugatti is considering collaborating with Porsche and Rimac to develop a pure-electric hypercar. Italian manufacturer Dallara, which constructs carbon fiber chassis for race cars in IndyCar and Formula One, may also be involved with the project.

In addition to more limited-edition Chiron variants, Bugatti could also add a second car to its line-up. A mystery model was recently spotted under a sheet sporting sedan proportions, suggesting that Bugatti’s Galibier concept could finally be entering production. Fingers crossed.

* Lower Auxiliary Air Temperature Sensor



* Auxiliary Inside Air Temperature Sensor



A signal and low reference circuit enables the sensor to operate. As the air temperature surrounding the sensor increases, the sensor resistance



decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40 to +101锟斤拷C



(-40 to +215锟斤拷F). The sensor signal varies between 0-5 volts. The HVAC control module converts the signal to a range between 0-255 counts. As the



air temperature increases the count value will decrease. If the HVAC control module or auxiliary HVAC control module detects a malfunctioning



sensor, then the control module software will use a defaulted air temperature value. The default value for the ambient and inside air temperature



sensors will be displayed on the scan tool. The default value for the duct air temperature sensors will not be displayed on the scan tool. The scan tool



parameter for the duct air temperature sensors are the actual state of the signal circuit. The default action ensures that the HVAC system can adjust



the inside air temperature near the desired temperature until the condition is corrected.



Diagnostic Aids



Conditions for Running the DTC



Ignition ON.



Conditions for Setting the DTC



The HVAC control module detects the temperature sensor signal circuit is less than -36锟斤拷C (-38锟斤拷F) or greater than 215锟斤拷C (419锟斤拷F) for greater than 15



seconds.



Action Taken When the DTC Sets



The system operates using a default value.



Conditions for Clearing the DTC



* The DTC will become history if the HVAC control module no longer detects the condition that set the DTC.



* The history DTC will clear after 100 fault-free ignition cycles.

Listen To The Bugatti Divo's Earth-Shattering Exhaust Note

All will be revealed next month.

The wait is nearly over for Bugatti’s latest bonkers hypercar, as the Divo will break cover at Pebble Beach next month. Before the covers come off, the teaser campaign is starting to gain traction, as Bugatti has released a new teaser video previewing the car's taillight design. Bugatti has said the Divo will adopt a “new, strong design language” and this teaser confirms that.

In contrast to the Chiron’s full-width light strip, the Divo will adopt separate clusters featuring dozens of LEDs. We also get to hear a sample the Divo’s earth-shattering exhaust note. What you’re hearing is likely a tuned version of the Chiron’s 8.0-liter quad-turbo W16 engine.

In the Chiron, this unit produces 1,479 horsepower and 1,180 lb-ft of torque, but it remains to be seen if the Divo will be more powerful. Thanks to enhanced aerodynamics, it should be quicker off the line, though – that’s no small feat considering the Chiron accelerates from 0-62 mph in 2.5 seconds. Another teaser image released by Bugatti previews the car’s extreme aero package showing an aero blade made from carbon fiber. This will make the Divo more agile for attacking corners and improve the handling “in a significantly more performance-oriented way.”

In other words, the Divo will be more track-focused than the Chiron, and even lighter than the Chiron Sport. Production will be limited to just 40 units, each costing $6 million. The Bugatti Divo will break cover on August 24, but expect more teasers to be released in the meantime.
