Weekly Recap: Racing legend Jim Hall explains Chevy's futuristic Chaparral concept

"I said our cars are built to be winners." – Jim Hall Racing legend Jim Hall never thought he'd be a video game consultant, but when Chevrolet asked for his advice to create a futuristic Chaparral for the Vision Gran Turismo series, he was eager to help. He reviewed early sketches and suggested some changes that made it onto the concept, including the addition of a camera that's mounted onto a mast over the cabin to aid the driver. The Chevy Chaparral 2X Vision Gran Turismo concept was revealed this week at the Los Angeles Auto Show and will be part of a downloadable update for PlayStation 3's Gran Turismo 6 in December. Theoretically, at least, it uses a laser-beam propulsion system and an air-powered generator to produce 900 horsepower in the video game. It's capable of sprinting to 60 miles per hour in 1.5 seconds en route to a top speed of 240 mph. Those gaudy performance specs – even in the virtual world – came at Hall's urging. "I said our cars are built to be winners," Hall told Autoblog on the floor of the Los Angeles show. The 79-year-old drove Lotus racecars in Formula One before launching the successful Chaparral Cars in the 1960s. Like his innovative Can-Am racers, the Vision Gran Turismo project has an eye toward the future. It also introduces the iconic Chaparral name to a new generation of fans, and hopefully, Hall says, gets them excited about engineering and design. "It emulates what we did in the '60s," he said. And what they did back then still resonates. Chaparral Racing and Chevy partnered more than 45 years ago for development work on the composite monocoque chassis, lightweight alloy powertrains, automatic gearboxes and active aerodynamics. "He [Hall] walked right back into this and was able to apply thinkings and learnings," said Clay Dean, General Motors executive director of advanced design. The Chevy Chaparral 2X Vision Gran Turismo concept was created at GM's North Hollywood advanced design studio, and it will be on display at the show through November.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Weekly Recap: Bentley Bentayga leads luxury SUV charge at Frankfurt

The Bentley Bentayga is launching a new era of ultra high-end sport utility vehicles that will see luxury makers vie for the world's richest and most exclusive customers. The Bentayga is Bentley's first SUV, and it will formally debut next week at the Frankfurt Motor Show. It's loaded with Bentley's best technology and features, led by a 600-horsepower W12 engine. The mission is simple: stop giving up sales to other companies by not having an SUV in its portfolio. "It creates an entirely new category of ultra-luxury SUV, where there are currently few rivals," IHS Automotive analyst Ian Fletcher said in a report. But Bentley and the Bentayga will soon face stiff competition. Archrival Rolls-Royce will produce its own crossover to be built in England, though timing is unclear. Lamborghini has approved plans for a ute that will be assembled in Italy and launch in 2018. Even the sportier British brands are getting into the market. Aston Martin will make a crossover version of the DBX concept shown earlier this year in Geneva, and Jaguar is launching the F-Pace crossover, which will debut in Frankfurt. These new entries will invigorate a segment that's comprised of the Mercedes G63 AMG and the Land Rover Range Rover SV Autobiography, and Bentley is poised to grab a large share of it, Fletcher noted. IHS forecasts Bentayga sales could hit 3,000 units per year in 2017 and 2018, pushing total Bentley sales to more than 10,000 in the next few years. The vehicle will also get plug-in hybrid and diesel variants to widen its reach. The Bentayga is a sales grab, for sure, but Bentley took care to ensure the SUV remained true to the brand. It's laden with the top-shelf wood, leather, and metal, and it comes standard with an expansive panoramic glass roof. It also has intelligent features like electronic night vision and an optional responsive off-road system that can be configured to adapt to eight different settings. It's a different kind of Bentley, but it's a harbinger of things to come for the world's richest luxury makers. Other News & Notes Toyota debuts next-gen Prius Toyota revealed the next-generation of its iconic fuel-sipping hybrid, the 2016 Prius, at an event in Las Vegas. The car promises 10-percent gains in fuel efficiency, though actual figures – and even powertrain specifics – were not revealed. We estimate that could mean about 56 miles per gallon in city driving and 53 on the highway.
