Weekly Recap: Geneva's splendor reflects growing demand for ultra-luxury cars

Geneva is one of the most glittering auto shows in the world, but the list of high-powered and bespoke luxury cars was decadent this year even by the rich standards of the Swiss exhibition. It's great for enthusiasts to revel in the flame-throwing Aston Martin Vulcan, the racing-inspired elegance of the Bentley EXP 10 Speed 6 concept and the insane performance of the Lamborghini Aventador LP 750-4 Superveloce, but there's a reason for all of this opulence: the luxury market is big business. And it's growing. IHS Automotive forecasts that so-called ultra-premium sales will nearly triple this decade from 123,000 to 353,000 units around the world. The estimate includes brands like Aston Martin, Bentley, Ferrari and Rolls-Royce, but doesn't count BMW, Mercedes and Audi, which offer less expensive models in addition to their high-end flagships. Though IHS includes Porsche and its relatively large volume in the study, the ultra-premium segment is still set grow at about the same rate, even without the German automaker's figures. So what is propelling all of this growth in the most expensive segment of the auto industry? Put simply, there's more rich people. IHS Automotive principal analyst Tim Urquhart pointed to economic expansion in China, market recovery in the United States and a surge in the lucrative technology sector as contributing factors. This dovetails with a research report by UK-based Oxfam, an international relief organization, which found the world's richest one-percent owned 48 percent of global wealth in 2014, and it's expected to increase to more than 50 percent by 2016.

"Ultra-premium carmakers are looking to explore ways of growing their product offerings, and thus their bottom lines, in this most potentially profitable of segments," Urquhart wrote in a report on the Geneva show. In a nutshell, there are more choices for people with more money. It's a good time to have expensive taste. Other News & Notes 2016 Mazda MX-5 Miata production launches It won't be long now.

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.

Next Chevy Volt will be 2016 model and ride on new chassis

What do we know about the 2016 Chevy Volt? Well, for now, all we can do is try to put the puzzle together without the box. Thankfully, a new batch of pieces has arrived from a new report in Edmunds, which says that the 2016 model year will introduce the second generation of a car that hasn't been dramatically updated since it went on sale in 2010. The new Volt is getting an "evolutionary styling change" and will ride on a new front-drive platform that has been developed by General Motors. GM's Kevin Kelly told AutoblogGreen that he has "no comment on future products," but he did acknowledge that Chevrolet is working on a second-generation Volt, "but I can't say anything about timing." Everybody already knew that a next-gen Volt is coming, so that's not a surprise. What we don't know is any real concrete information on the car itself. The few tidbits of information we do have help define the outlines of the next version of Chevy's halo car, but they're not confirmed yet. For the record, they range from the eye-raising (a $10,000 price drop) to the logical (20 percent more electric range). We can't see the whole picture yet, but the pieces do point to the 2016 Volt, which would be released next year sometime, being a much bigger deal than the last update, when the Volt's range was increased by three electric miles thanks to a battery capacity increase of 16 kWh to 16.5.
