Audi announces 2015 A3 pricing

The last A3 we drove, an Irish-spec model with cloth seats and a 1.4 TSI engine paired with Audi's S-tronic twin-clutch gearbox, retailed for $54,495. Thankfully, American buyers won't face that sort of out-the-wazoo payment when the new sedan arrives early next year. Audi's announced a price that takes a direct shot across the bow of rival Mercedes-Benz' CLA: $29,900.

McLaren 650S priced from £195,250 and does 0-62mph in 3.0 seconds

The new McLaren 650S (pictured) costs from £195,250 It’s only ten days since the McLaren 650S was revealed as a more hardcore version of McLaren 12C supercar – and with more than a hint of P1 styling – but McLaren are already building it and have revealed performance and price details. Available as either a 650S Coupe or 650S Spider, the starting point is £195,250 for the Coupe and £212,250 for the Spider, that’s almost £20k more for the 650S Coupe than the 12C Coupe and £17k more for the Spider. But apart from the more dramatic styling, increased downforce and tweaks from the extra power – the 650S gets 641bhp – to the improved handling and dynamics, you also get increased levels of optional equipment including carbon racing seats from the P1, rear parking camera and full carbon fibre interior.

HBH tunes an Aston Martin V12 Vantage into the Bulldog GT

We love one-off specials here at Autoweek almost as much as we love the supercars upon which they're based. And if you're a tuner trying to pick a good chassis, we can't think of a much better place to start than the Aston Martin V12 Vantage. That's what Danish company HBH did for its Bulldog GT.
