Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

Junkyard Gem: 1987 Chevrolet Turbo Sprint

Fifteen years ago, I wrote my first-ever automotive article under the name Murilee Martin, and it didn't take me long to start writing about one of my favorite automotive subjects: the junkyard. Before I'd refined my system for documenting discarded vehicles, however, I shot a lot of boneyard photos that never got used. For today's Junkyard Gem, I have four shots from early 2007 of one of the rarest turbocharged machines of the 1980s: the Chevrolet Turbo Sprint. The Chevrolet Sprint was really a rebadged Suzuki Cultus, from the pre-Geo era when General Motors sold the Isuzu Gemini as the Chevrolet Spectrum, the Daewoo LeMans as the Pontiac LeMans and the Toyota Corolla as the Chevrolet Nova (soon enough, the Spectrum became a Geo, and the Nova became the Prizm). The second-generation Cultus appeared in 1988, becoming the Geo Metro on our shores the following year. The Turbo Sprint was available for just the last two years of the Sprint's 1985-1988 American sales run, and it appears that just a couple of thousand were sold; if I'd known at the time just how rare they were, I'd have shot more photos of this one at the now-defunct Hayward Pick Your Part. The turbocharged 993cc three-cylinder produced 70 horsepower, 22 better than the naturally-aspirated version. Since the Turbo Sprint weighed just 1,620 pounds (that's about 500 pounds lighter than a barely more powerful '22 Mitsusbishi Mirage), it was plenty of fun to drive. For 1988, the regular Sprint hatchback cost $6,380 while the Turbo Sprint listed at $8,240 (that's about $15,375 and $19,855 today, respectively). Believe it or not, a Turbo Sprint actually raced in the 24 Hours of Lemons 10 years ago, though it didn't end well. This ad is for the regular Cultus, not the Cultus Turbo, but the screaming guitars sound reasonably turbocharged. For the most part, Chevy Sprint marketing was all about cheap purchase price and stingy fuel economy… at a time when gasoline prices were cratering. Related Video:

2017 Chevy Corvette Grand Sport brings American fury to Geneva

Power isn't everything – even when it comes to Corvettes. Sure, the mighty, 650-horsepower Z06 is a real peach, but there's a lot to be said for the base Stingray with its naturally aspirated LT1 V8, putting out 460 hp in top spec. That's still plenty of grunt. Now, put that engine in a lightweight, aerodynamic-focused Corvette with super-sticky tires, and you get the new Grand Sport – a naturally aspirated Stingray that can pull up to 1.2 Gs. GM says the new Grand Sport is nearly as quick around its Milford Proving Ground track as the previous-generation ZR1. Specific updates include sticky Michelin Pilot Super Sport summer tires – 285/30ZR19 up front and 335/25ZR20 at the rear. Huge Brembo brakes are fitted to slow things down with a quickness, new stabilizer bars and springs keep the car hunkered down, and a seven-speed manual and eight-speed automatic transmissions are available. Want an even more hardcore package? Option the Z07 pack, which adds carbon ceramic brakes and Pilot Sport 2 Cup tires. Both coupe and convertible versions will be available, and a Collector Edition will come later in the year, painted in Watkins Glen Gray with Tension Blue hash marks, satin black stripes, black wheels, and a blue full leather and suede interior. The 2017 Corvette Grand Sport debuts at this week's Geneva Motor Show, and will go on sale in the US this summer.
