BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins

BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Car companies may need to start curbing model proliferation

Looking at the current automotive landscape, especially from German makers, you quickly get the impression that less definitely isn't more. BMW alone offers its 3 Series platform in practically every segment possible, including the regular sedan and 4 Series Gran Coupe, which would seem to be direct competitors. Porsche might be the winner, though, with 20 different variants of the 911 listed for sale on its US website. However, some of this model madness might be reaching an end as companies begin cutting back spending or shifting money to other priorities.
According to Yahoo Finance, the offerings from the German automakers are up 25 percent over the past three years to over 200 models in Europe. The peak is expected to come around 2018 at 230 separate vehicles, according to consulting company PwC.
Amazingly, BMW, which is among the poster children for this model explosion, might be changing its tune. "I'm sure there will be points in the future where we look at certain cars and say, 'Maybe we need to think differently now,'" said head of sales Ian Robertson in an interview, according to Yahoo Finance. The statement certainly sounds shocking coming from a company rumored to have 23 front-wheel-drive vehicles all using a single platform on the way.
