The Camaro Reminds Me that it’s Time for a New Trans-Am

March 21st, 2009

No, not the Pontiac version.  I’m talking about the SCCA Trans-American Sedan Challenge — Trans-Am for short — after which the Pontiac ponycar was named.  The series’ fortunes have ebbed and flowed over the years.  It went away for 2007-08, and it’s just now making a return.  I wish it well, but its not what Trans-Am was, or in my opinion, should be.  Like NASCAR, its all tube frame stuff now, the cars are several years old, and the rules are pretty loose about what can and can’t play.

The original Trans-Am, born in 1966, was based on race-modified versions of real street cars. There were two categories: big-bore cars, from 2. [More....]

2010 Camaro: Running the Numbers

2010 Chevrolet Camaro SS burnout

Yesterday, March 19, 2009, dawned clear, bright, and cold in Milford, Michigan — just 33.9 degrees at the General Motors Proving Ground. Parked next to the mile-plus-long Military Straight was a multi-colored selection of Camaro RS and SS models representing each of the four drivetrain combinations: V-6 and V-8 engines, manual and automatic six-speed transmissions. Each was well equipped, with both V-6s shod in the optional performance-enhancing 20-in. tires, so that all four cars rode on identical Pirelli PZeros, sized 245/45ZR20 in front, 275/40ZR20 in back, each set to 36 psi all around. Editor’s Note: The Camaros shown in motion are from our photo shoot this week outside of San Diego by MT photographer B [More....]

Reinventing the (Forged) Wheel

Alcoa die-sublimation wheel tattoos

Aluminum giant Alcoa doesn’t get much press for its wheel business, because about 90 percent of it is supplying factories with original-equipment wheels, and those don’t get rolled out with fanfare and SEMA-show babes draped over them. But Alcoa has been quietly innovating on the wheel front, and some of the good ideas for mass reduction (and commensurate fuel economy and performance improvements), and durable new finishes that are rolling out now or in the near future seemed worthy of a little rundown.

The Future of BMW’s M Division: New Turbo Fours and Sixes Likely

MUNICH, GERMANY — Mark the 2014 model year on your calendars, M fanatics. That’s when BMW plans to introduce M versions of its next 3 Series and its second-generation 1 Series coupe, both due for redesign in the 2013 model year. While it’s too early in BMW’s planning stages to say for certain exactly what will power those Ms, the tuning division’s CEO, Ludwig Willisch, revealed M’s thinking at a roundtable interview here Wednesday morning.

Along with everybody else, BMW faces strict, new U.S. Corporate Average Fuel Economy and European Union CO2 standards, and must power lighter cars with more fuel-efficient engines. A turbo-six will replace the M3’s 400-horsepower, 4.0L V-8 and a 300-plus-horsepower turbo four w [More....]
