BMW pondering hardcore M4 to celebrate 100 years?

2013 is the year for Lamborghini, Aston Martin and the Porsche 911, but 2016 will be the year for BMW. That's when the Munich-based maker of the Ultimate Driving Machine will celebrate its 100th birthday, with what will probably be a year-long celebration. Part of that 365-day party will, reportedly, be an even hotter version of the new BMW M4, which is set to debut in January at the Detroit Auto Show.
Yes, according to Australia's Car Sales, the über-M4 has been hinted at by higher-ups at BMW's M division, who claim the rear seats will be removed, much like the M3 GTS, while other weight-saving measures will be used to try and bring the M4's weight below 3,000 pounds. There's no mention of engine mods, but if the M4's biturbocharged six is as good as we think it'll be, that's not a deal-breaker for us.
The lightening process on the so-called M4 GTS would involve replacing the hood and front fenders with parts made of carbon fiber, while the doors would switch from steel to aluminum. Besides the deletion of the rear seats, Car Sales is predicting lightweight racing buckets, with a carbon-fiber shell and a minimal amount of padding. Expect lots and lots of Alcantara, in place of leather.

BMW, Toyota outline new tech joint venture, new sports car

Back in June, Toyota and BMW announced a "memorandum of understanding" outlining plans for the two companies to join forces on future products and technology development. On Thursday, they signed a more formal and binding agreement that goes further into detail about the partnership, and it all sounds pretty exciting. The two announced they will work together in four main areas:
Joint development of a fuel cell system
"Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle"

BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.
