Cadillac abandons plans for six-digit flagship sedan

So much for that party. Cadillac has announced that it is walking away from plans to build a high-dollar, rear-wheel-drive ultraluxury sedan. The low-volume model would have been based on the lusty Ciel Concept, and the production iteration would have carried a price tag well over $100,000. Executives with the automaker reportedly claim the model wouldn't have bolstered the brand enough to be worth the investment.
Even so, Automotive News reports Cadillac is still on track to build a range-topping four-door to go head-to-head with the BMW 7 Series and Mercedes-Benz S-Class. That model will likely be constructed on the company's upcoming Omega rear-wheel-drive platform, but we won't see it bow until at least 2016. Right now, the front-wheel-drive XTS sits at the top of the Cadillac lineup, and while that machine and it's twin-turbocharged V6 variant makes a compelling argument against certain luxury entries, it falls short serving as a legitimate competitor for the likes of the 7 Series and S-Class for enthusiast drivers.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

The 2016 Pebble Beach Concept Lawn was nuts as always

The Concept Lawn at the Pebble Beach Concours d'Elegance is like the smallest, most expensive car show you can imagine. A bunch of unobtanium concepts and almost-production models line an irregularly shaped putting green for people to stare at while on their way to see other, older insane cars. This year's crop was a particularly good one. We'll walk through the gallery above in order: That's a new Ford GT. Not quite a concept, but it's not in production yet, so we'll let it slide. Then there's the one-of-a-kind Bugatti Vision Gran Turismo that was recently bought by a Saudi Prince along with a matching Chiron. Next up is the Lamborghini Centenario Roadster, which was unveiled last week and is already sold out. This orange automobile is BMW's 2002 Hommage with its latest livery, a Jagermeister-themed affair called Turbomeister. This silver Infiniti, the Q80 Inspiration Concept, is an oldie but a goodie. It first appeared in Paris in 2014. The extremely long automobile after that is the Vision Mercedes-Maybach 6, which was unveiled in Monterey this year. The 6 in the name is because it's 6 meters, or about 18 feet, long. Most of that's the hood. Next we have the one-of-99 Aston Martin Vanquish Zagato coupe, which continues to be beautiful. After that is a Fisker Karma with a V8, the VLF Destino. Thank you, Bob Lutz. The black sedan you see after that is the Cadillac Escala Concept, which also made its debut in Monterey this year. Then we have a Rolls-Royce Wraith Black Badge. Not a concept, but exclusive enough to join the others. Next is the McLaren 570GT customized by MSO that arrived for Pebble 2016. It has special design touches plus an electrochromic panel to replace the normal glass roof. The light blue car is the Genesis New York concept. The name didn't change even though it was in Monterey. Then we have the large and in charge Lincoln Navigator concept, taking up two regulation concept spots. The red car with suicide doors is Acura's Precision Concept, which we first saw at the Detroit show this year. Another non-concept, the Lexus LC 500h at least looks futuristic enough to be a show-specific car. And here's a 2017 Maserati Quattroporte, which is definitely not a concept. A Bentley Mulsanne EWB, because why not? It's not available in the US, so that almost qualifies for concept status. Then there's a reproduction Lister Knobbly, which we could stare at all day.
