TWO Koenigsegg One:1 on video at Goodwood

Both Koenigsegg One:1s on video at Goodwood As we’ve already reported, the Koenigsegg One:1 is debuting at the Goodwood Festival of Speed this weekend, but rather than a single One:1, Koenigsegg have taken the only two One:1s in existence – yes, it’s two for the price of one at Goodwood. One car – the black one in the photo above – is a new One:1 heading for a customer, but the second (the silver can in the photo and video) is Koenigsegg’s development car, so that’s up for a bit of action on the hillclimb this weekend. But ahead of its public appearance, Goodwood managed to get some time with the One:1s and grab track time behind the wheel.

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.
