McLaren MP4-12C GT3 (2011) track testing begins

McLaren has begun testing its latest track weapon, the MP4-12C GT3 ahead of the 2012 FIA GT3 season.  How different is the MP4-12C GT3 from the roadgoing edition? The MP4-12C GT3 is based on the standard machine but modified for FIA GT racing by McLaren GT - a joint venture between McLaren Automotive and CRS Racing, a UK-based team currently competing in FIA GT with Ferrari F430s.  Externally you'll notice the race-spec fixed rear wing, undertray diffuser, front splitter, louvres and vents. Underneath there's a new suspension system, ditching the road car's linked suspension for FIA-compliant conventional dampers and anti-roll bars. Akebono is supplying race-specific brake components, and Bosch Motorsport has installed its ABS system. The car sits 100mm wider on its new suspension and has suitably flared bodywork as a result.  It's still the McLaren's bespoke 3.8-litre twin-turbo V8 engine, tuned for racing.

Video: Peter Schreyer on premium proportion

Kia has released a short film featuring Peter Schreyer that provides an insight into the world of premium car design in which he explains the importance of proportion. In the presentation, Schreyer sketches the company's new K9 sedan, describing how a rear-wheel drive platform affects the car's design, with its generous wheelbase, short front overhang and the 'prestige distance' between the center of the front wheel and the A-pillar.

BMW Alpina B7 gets power boost for 2013

The 2013 BMW Alpina B7, the performance version of the German automaker's 7-series sedan, gets an additional 40 hp--and a more costly sticker price--for the new model year. BMW plans to roll out the 2013 model at the Pebble Beach Concours d'Elegance in August and begin sales soon thereafter. Under the hood, power from the 4.4-liter V8 has been increased from 500 to 540 hp with the addition of BMW's throttle-less Valvetronic intake system.
