Driven: BMW Z4

Loved as it may be by its loyal fanbase, the outgoing Z4 was always something of a mixed bag in terms of design. While the car's classic long-bonnet, cab-back profile and short overhangs should have pleased the eye, the BMW's sheer frontal mass made its proportions seem out of balance. The application of the company's then-new ‘flame surfacing' form language also generated a visual business that seemed out of place on something as conceptually simple as a roadster.

Many enthusiast rides post strong sales in 2010

The fast and the luxurious models from a wide range of carmakers sold briskly in 2010, offering heart to enthusiasts that their favorite drives have bright outlooks and that the auto business is on the rebound.

In the Camaro's first full year since production ended after the 2002 model year, Chevy rung up 81,299 Camaro sales, beating Mustang by 7,583 cars.

Porsche 918 Spyder laps Nurburgring in under 7 minutes

The Porsche 918 Spyder (pictured) laps the Nurburgring in under 7 minutes When the McLaren P1 was first revealed, Ron Dennis told us it would lap the Nurburgring in under 7 minutes. But it seems the best the McLaren P1 has managed so far is a 7:04, so it’s no surprise McLaren hasn’t officially declared its time as they probably knew it wasn’t enough, but also knew that Porsche has managed to take the new 918 Spyder round the ‘Ring in just 6:57s. That 6:57 by the Porsche 918 Spyder isn’t quite as quick as the Radical, but as the Radical has only single type approval, Porsche are justifiably claiming the 918 Spyder’s time as the quickest by a proper production car, beating the previous record of 7:11s set by the Gumpert Apollo.
