A bigger stick for the soft-spoken supercar, and a price to match. By making available an R8 with a monster 525-hp V-10 engine—complementing the 420-hp V-8 model that was introduced two years ago—Audi has elevated its exotic-looking two-seater from “almost-a-supercar” status to a true competitor in the high-performance realm above mere sports cars. The 105-hp increase comes from a 5.2-liter, direct-injection V-10 that is virtually identical to the engine found in the Lambor ghini Gallardo LP560-4. Unique engine programming and intake and exhaust systems are the chief differences in the Audi engine over the Italian job, although both engines are made in the same plant in Hungary. We’re told that the V-10 weighs just 68 pounds more than the V-8, and that fuel economy with the bigger engine will worsen by only 1 mpg. Output is listed by Audi at 525 horsepower and 391 pound-feet of torque, 27 horses and seven pound-feet fewer than in the Lambo, but we suspect some of that difference is sim...

Torque is described as a force that tends to turn things and, in the case of the 2009 Jetta TDI, its abundance turned me into a fan of this latest in a long line of Volkswagen "oil-burners" by providing strong performance and flexibility along with exceptionally high levels of fuel economy. Torque is what you get when you, for example, tug on the handle of a wrench to tighten or loosen a nut. Doing so exerts a twisting force still expressed here, in Ye Olde English, in lb-ft, as nobody on this side of the Atlantic has any idea what a newton-metre is. Torque in an engine is generated by burning a fuel/air mixture in a cylinder, with the pressure of the expanding gases pushing the piston, which is linked to the crankshaft by a connecting rod, downwards. As this occurs, the angle generated by the crankshaft "throw" increases and the rod, like the wrench handle above, rotates the crank. And that, with a few things such as clutches and transmission gears in between, is w...

If the 2009 Infiniti G37 Convertible is the answer, the question, Alex, is, “What took them so long?” Indeed, the first and last droptop Infiniti before the new G37 Convertible was the 1990-’92 Infiniti M30 Convertible, a rebadged Japanese-market Nissan Leopard without its roof. The current Infiniti G-series models inevitably indulge in sharing its “FM” platform with the Nissan Z-models, but with two decades of maturation at Infiniti the model line is more independent and the G-series not the stopgap the original Infiniti M-series was. The subject 2009 Infiniti G37 models were designed from the outset to accommodate the convertible version. It’s not a conversion or chop-topped Coupe. But it’s also not a roadster, like the topless version its corporate cousin S-cars, but a convertible with a with a rear seat. Never mind that it’s a bit snug back there, real adults will fit. The only way that will happen with a Z roadster is by putting the extra people on the rear deck like homecoming ki...

A Mustang with a Track pack? Corvettes and Vipers grab the glory for Old Glory at temples of speed such as Le Mans. The lumbering, log-axle Mustang is just a quarter-miler for the tattoo-and-tobacco crowd, right? Actually, mes amis, the Mustang is America’s other road-racing workhorse. It has its own pro series, the eight-race Mustang Challenge. And there were more than a dozen Mustangs on the grid at Daytona this past January when a Roush-prepared Mustang finished second in the three-hour Koni Challenge race. It made all its rights and lefts better than Porsche 911s and BMW M3s. No, we wouldn’t expect that hierarchy to hold on the street, even if the 2010 Track-pack Mustang GT is billed as the hairpin-and-carousel king of the newly reskinned Mustang lineup. Still, Ford’s old pony has a long history of making incremental improvements as it ages, and the Track package shows that the late-night lights still burn in some windows at Ford. Building a Track-pack Mustang on the order form sta...
