The new BMW M4 GT4 carries the factory-prepped race torch

Purchasing a factory-prepared race car is a relatively easy thing to do, if you have the means. A number of manufacturers, from Mazda to Porsche, sell cars that are race-ready straight out of the box. BMW, following on the success of the E92 generation M3 GT4, announced today that an M4 GT4 will be ready for the 2018 season. The GT4 spec is the lowest class of FIA GT racing. It's meant for amateur racers, and as such the regulations are quite strict. Every car must have at least one amateur driver, and the rules as to what constitutes as an amateur are very specific and clear. Aside from BMW, Aston Martin, Porsche, and Toyota all field cars in GT4 spec races. Like the M3 GT4, the new version of the M4 comes from the factory homologated to FIA GT4 spec. BMW says the M4 GT4 will use the standard coupe's 425 horsepower twin-turbocharged 3.0-liter inline six cylinder engine, including the electronics – the outgoing M3 GT4 used the standard car's 420 hp, high-revving, 4.0-liter naturally-aspirated V8. The new car will also pull bits like a carbon fiber hood from the M4 GTS. Specific details like weights or fluid capacities haven't been revealed, nor has the transmission been confirmed. It's unclear if the M4 will be heavier than the smaller outgoing M3, which weighed slightly over 3,000 lbs. Expect things like built-in air jacks, a roll cage, lightweight seats, and other race-ready parts to carry over. The M4 GT4 will start testing at the end of 2016 in preparation for a 2018 debut. Customers with who can't wait can purchase one of BMW's other race-ready offerings. BMW currently sells the M6 GT3 and M235i Racing. Parts like the pedal box, brakes, and seats for the M4 GT4 are the same as those in the M6 GT3. Pricing hasn't been announced, but the current M3 GT4 sells for about $140,000. The car should go on sale late next year. Related Video: Motorsports BMW Racing Vehicles bmw m4

BMW i8 customized by AC Schnitzer [w/video]

It may not enjoy the kind of factory support that Alpina does (let alone Munich's own M division), but as far as independent BMW tuners go, few have the kind of clout that AC Schnitzer does. Heck, it even won the DTM championship for BMW in its first year back in the series. And now the legendary Bimmer tuner has turned its attention to the i8. The list of Schnitzer's enhancements for the plug-in hybrid sports car is long, but perhaps wisely shies away from messing with the intricate powertrain. Instead the customization options focus on elements like the suspension, rolling stock, aero kit, and interior. AC Schnitzer has dropped the ride height by almost an inch at the front and 0.78 inches at the rear. It's fitted a set of 21-inch forged alloys with five split spokes and low-profile rubber to trim nearly ten pounds off the vehicle's unsprung weight while increasing its contact patch for better grip (albeit likely with higher rolling resistance). There's also a comprehensive rolling kit made of carbon fiber, including front spoiler elements, side skirts, and a rear wing that to our eye looks a little out of place on the i8, though individual customers may disagree. And the interior has been upgraded with aluminum pedals and velour floor mats. Of course customers will be able to pick and choose which elements they'd want to install on their hybrid vehicles, but you can check out the fully spec'd demonstrator in the high-resolution image gallery above and in the video below. (You just may want to turn down your speakers if you're not into German techno-pop.) Revolutionary Sporting Performance and Innovative Design The i8 by AC Schnitzer emphasises the strengths of the plug-in hybrid from Munich The BMW i8 is revolutionising its vehicle class as the first sports car to have the fuel consumption and emission values of a small car. Now thanks to AC Schnitzer, this revolution is being followed by another: the AC Schnitzer special equipment for the BMW i8 emphasises even more clearly the sporting performance and innovative design of the powerful, environmentally-friendly coupe. Lowered by 25 mm at the front and 20 mm at the rear, the i8 by AC Schnitzer hugs the tarmac more closely than the standard vehicle and can therefore develop maximum efficiency and dynamics on the road.

Tesla in talks with BMW about batteries, charging collaborations

With Toyota and Daimler no longer holding Tesla shares, the electric vehicle company might be looking for a new partner – possibly a Bavarian one. In a new interview with Germany's Der Spiegel, CEO Elon Musk confirmed that he has had talks with BMW execs about future collaboration. "We are talking about whether we can collaborate in battery technology or charging stations," Musk said in the interview, according to Reuters. However, a Tesla spokesperson has tempered things by saying no formal agreements are in place at the moment. In the same interview, Musk reportedly praised BMW's use of carbon-fiber-reinforced plastic in its i sub-brand offerings, and said he would like to have a battery factory in Germany in the next five or six years. The possibility of technological cooperation between Tesla and BMW has been a hot topic this year. In June, Musk reportedly met with BMW execs, and the two companies were also rumored to have met with Nissan to discuss charging technology. When Daimler sold off its shares, there was talk of it opening the way for possible collaboration between the two automakers, as well.
