New TLX A-Spec leads Acura's three-car Pike's Peak attack

Once again, Acura is headed to Pikes Peak for the hillclimb on June 25 with a small group of machines. This year the focus is on the TLX, with two vehicles bearing the sedan's name and shape. The two cars are very different, though, and will compete in two different classes. The first is the TLX A-Spec. This started life as a production TLX, but the 3.5-liter V6 has been reworked with pistons, rods, camshafts, and a valvetrain from Acura's TLX GT race car. The engine also has a turbocharger, which helps the V6 make an impressive 500 horsepower. All those ponies go to the front wheels through a limited-slip differential. In addition to the powertrain upgrades, the interior has been gutted, and a big wing and front splitter fitted. The A-Spec will compete in the Pikes Peak exhibition class. The other TLX is a TLX GT. This is the type of car from which the A-Spec borrows engine components, but not the TLX GT's twin-turbocharger system. TLX GTs have already been competing in motorsports, specifically in the Pirelli World Challenge. Acura did make some changes to this car for Pikes Peak, though. The suspension and engine computer have been tweaked, gear ratios shortened, and additional aerodynamic bits added for more downforce. The TLX GT will compete in the open class. Despite the focus on the TLX, Acura is still bringing an NSX to the hill climb. This car is similar to the one that raced in the Time Attack 1 class last year, but has some changes for the Time Attack 2 class. Most notable of these changes are the massive rear wing and front splitter. According to Acura, these aerodynamic aids were based on those used for the NSX GT3 race car. Acura also reduced weight, changed the tuning on the engine computer, and fitted sticky R-compound tires.

No S660 for US, but Honda wants sporty cars

Honda, best known lately for being a mainstream player rather than the brand that brought us the CRX Si, NSX, Integra Type-R, and S2000, apparently wants to builds sporty cars for the US again. With that in mind (or not), Honda has ruled out bringing the tiny, sporty S660 roadster across the Pacific. "I wouldn't put my chips on [the S660]," American Honda Executive Vice President John Mendel told Automotive News. At nearly 11.1 feet long, the S660 slots in between the 12.8-foot Mazda MX-5 Miata and the 8.8-foot Smart ForTwo. Yet Mendel says the tiny two-seater wouldn't work here. "When the practicalities of the market come in, and the car only so big, that might not be the best car for the US market," Mendel said. "It might be better for India or China or somewhere else." Honda is considering its options here in the US, though. As AN reports, after his takeover earlier this year, new CEO Takahiro Hachigo promised more sporting models, like the new, US-bound, 300-horsepower Civic Type R. And while it's no secret that Honda has filed patent drawings for a mid-engine model, Mendel offered little to indicate that it'd become a reality. Calling the project from Honda's Silicon Valley research and design facility a "design study," Mendel wouldn't answer AN when it asked whether this new model was successor to the S2000 or a more attainable, lower-powered NSX. He did, however, say his company was getting pressure from dealers over the lack of verve in the company's lineup. "They want anything in the sports car world," Mendel told AN. "They're going, 'Gimme a sports car.' They want a retractable hardtop; they want a high-horsepower $20,000 sports car. Because that's the nature of what they do." There you are, Honda. Your dealers want it, which means your consumers are probably are asking for it, and your CEO wants it, too. Make something happen.

MotorWeek remembers retro icons, Supra and NSX

It's easy to poke a joke here and there about John Davis, the long-time host of MotorWeek. His voice is so monotonous that, from time to time, if you closed your eyes, you may think it's generated via a computer. But you have to give him and the rest of the show a lot of credit. The program has been on the air for decades, giving people direct, straight-down-the middle automotive reviews.
MotorWeek's massive back catalog of reviews are slowly making their way onto YouTube, and they provide a fascinating chance to look back on how performance cars rank against their contemporaries from back in the day. Two recent additions include the show's old looks at the 1986 Toyota Supra, the dawn of the third-generation model, and the now-iconic 1991 Acura NSX.
Both reviews are interesting in their own way. These days you hear nary a negative word about the original NSX, but MotorWeek isn't afraid to point out a few flaws. And the Supra really shows the progress of suspension tuning in the intervening decades because it has some serious body roll in the corners.
