BMW i3 ‘virtual test drive’ app (2013) CAR review

Though we’ve seen new the BMW i3 in full production trim, and had a ride in the carbonfibre electric city car, there’s still a short wait before anyone can get behind the wheel of a showroom-spec example in the UK – or is there? BMW has launched a smartphone and tablet app – ‘BMW i3: Become Electric’, which it claims allows users to virtually test drive the new i3 without so much as setting foot outside their front door, yet alone finding the time to head to a BMW dealership. It’s available now on the Apple App Store, and from 26 September 2013 on Google Play.

Concept Car of the Week: Pininfarina CNR-PF (1978)

In the 1970s alarm bells were ringing in the energy sector as a series of energy crises and rising fuel prices spiralled. The car industry was forced to produce a new generation of more efficient cars and designers were putting new models through wind tunnels to optimize their aerodynamic performance to reduce aerodynamic drag. Some pushed the limits further than others and none more so than Pininfarina, which designed a car that slipped through the air twice as efficiently than any other.

Jaguar XK leaves the lineup

Production of the Jaguar XK stretched from 1996 with the XK8 and will wrap up as the final 50 limited edition XK models roll off the assembly line this summer. The farewell XKs will be branded as "Final Fifty Limited Edition" cars, and will carry the same specification as the current XKR model, along with some added features that celebrate the history of Jaguar and the evolution of the brand's grand touring coupes and convertibles. Under the hood, a supercharged 510-hp 5.0-liter V8 is capable of bringing the XK to 60 mph in 4.6 seconds according to Jag, and an active exhaust system helps ensure the engine note remains prominent.
