Volvo gives T6 engine the Polestar treatment

Just weeks after announcing its Polestar performance kits for the T5-engined cars, Volvo is now offering packages for the XC60, S60 and XC70 models fitted with its turbocharged six-cylinder engine. The T6 Polestar software package adds 25 hp and 30 lb-ft of torque, bringing totals to 325 hp and 355 lb-ft, respectively. Volvo says the added power won't result in greater fuel consumption, as the tuning of the engine only increases power when needed--though we'd imagine most drivers will feel the need often enough to significantly affect mileage.

2013 Mercedes-Benz SLS AMG GT gets more letters, power

Two additional letters will spell more power for the 2013 Mercedes-Benz SLS AMG. The supercar will be named the SLS AMG GT for the next model year, which is meant to call attention to the light freshening that the glamorous two-seater will receive when it goes on sale in mid-November. Output grows to 583 hp from the naturally aspirated 6.2-liter V8, up from 563 hp in today's car.

Aston Martin DBS twins emerge from barn

Forgotten Aston Martins still turn up in barns and garages all over with world with some regularity, though rarely are they identical twins. This pair of DBS coupes emerged from more than a decade of storage in a barn just recently, and if it weren't for the license plates, we'd have trouble telling them apart. These two come from a large private collection, but both were tucked away after being acquired in largely original condition more than 10 years ago.
