Why the BMW M4 is better than the M3 V8 (2013)

It’s no exaggeration to say that the turbocharged engine in the upcoming BMW M3 (saloon) and M4 (coupe) models is one of the most important engines ever produced by BMW’s M Division. No, it’s not the first turbo lump the performance off-shoot has built – you'll probably know we’ve already had the X5/X6M mutants plus the brilliant 1M and M5 and M6 – but it is the first turbo ever to slot in a production M3, the car that personifies BMW’s iconic performance sub brand, which itself has always been defined by high-revving, naturally aspirated engines. All of this explains why M’s engineers have cut their teeth on other engines first before plucking up the courage to develop the M3/M4 turbo while turning their backs on the outgoing E92 M3’s exceptional V8.

BMW revives four-cylinders for better mileage

McLaren Automotive First Anniversary: 1,000 McLaren MP4-12C sold and counting

McLaren Automotive is a year old and is celebrating selling over 1,000 McLaren MP4-12Cs in the first twelve months.

But McLaren don’t seem to acknowledge that date as the start of McLaren Automotive but instead prefer the date the first MP4-12C was sold – exactly one year ago today on June 21st 2011.
