Bench Racing: New crop of supercars

It's been a while since we've hypothetically raced a handful of cars around the office; long enough that an entirely new crop of supercars has arrived for us to chart, graph and dissect. Today we're zeroing in on the $1-$3 million price tag range, which fits the Ferrari LaFerrari, McLaren P1, Pagani Huayra and the Bugatti Veyron Super Sport. The first three fit neatly, pricewise, at about $1.3 million.

Mazda CX-5 gets new trim levels

Mazda CX-5 gets new trim levels When car makers come up with trim specifications for their models, they do so in a way that gives easy stepping stones in equipment levels, from hair shirt to over the top. They also expect that many buyers will pay a visit to the options list to add in a few extra goodies to the standard spec, but it looks like Mazda has been getting the same request repeatedly from buyers of the CX-5 compact SUV – give us a sunroof and leather. Until now, the only way to get sunroof and leather was to opt for the range-topping Sport trim – which costs from £27.5k – but now Mazda has added two trim levels beneath the Sport - SE-L Lux and SE-L Lux Nav – which come already equipped with the two most requested extras.

New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10. Most of the new A6 range has now arrived in showrooms – including the S6 and Avant – but what’s still missing is a new RS6, the Audi that used to have the heart of a Lamborghini. But as we reported in April, the 2013 RS6 is well on the way but it will be losing its Lamborghini V10 with its 5.2 litres and 572bhp and will instead get the Audi/Bentley twin-turbo 4.0 litre V8.
