Final decision on Toyota/BMW sports car due by year end

BMW and Toyota signed a memorandum of understanding to share technology and build a sports car way back in 2012, and months later, they made that partnership official. This oft-rumored model from two auto industry titans still hasn't hit the road, and the time has come to make a final decision about its future. Thankfully, the model's fate is just a few months from being known. "By the end of the year we will approve whether or not we will make it," a Toyota spokesperson said about the sports car project, according to Automotive News Europe. "The whole study before that, on what kind of platform, on what kind of architecture, that's been progressing quite well. We haven't yet decided to give the green light to the project, but it's coming up." The collaboration is supposed to result in jointly developed fuel-cell tech, composites, and research into lithium-air batteries. Little is officially known about what Toyota and BMW are planning for the sports car project, but there are plenty of rumors about what's in store. Both automakers are supposed to get their own version of the vehicle. Some reports say the Japanese model will be the revival of the Supra, and the Bimmer-badged one might end up being a replacement for the Z4. The potential powertrains have been suggested as a German-sourced, turbocharged inline six with rear-wheel drive and a super-capacitor-powered plug-in hybrid with all-wheel drive.

BMW 1 Series prototype packs direct water injection

Just a few months ago, BMW showcased an M4 that was modified to serve as the safety car for the MotoGP racing series. The flashing lights and emergency equipment, however, weren't the only modifications BMW made to the performance coupe. It also packed an innovative new water injection system. And now it's furthering the development of that system by running it in a 1 Series hatchback as well. Revealed at the BMW Group Innovation Days 2015 event, this five-door 1 Series packs a three-cylinder gasoline engine – like the one found in a Mini or i8 – but fitted with the direct water injection system. In this application, the system sprays a fine mist of water – yep, regular old H2O – right into the combustion chamber. While mixing water with gasoline normally wouldn't be recommended, in this case it evaporates immediately and helps cool the engine from the inside, allowing it to run at higher efficiency. That cooler running engine brings with it several benefits. It delivers improved fuel economy and lower emissions, to start. It also allows for an earlier ignition point, higher compression ratio, and higher boost pressure in turbocharged engines, delivering increased output. It even cuts down on engine knocking (where combustion occurs spontaneously), reduces wear and tear on the engine, and makes better use of lower octane levels. If that sounds like a win-win-win... win (we're losing count of all the wins here), it's because BMW just may be on to something. Of course it does require a water tank to be fitted on board, which means added weight, but instead of requiring the driver fill up the water tank, BMW has fitted this prototype with a system that replenishes the water level from the air conditioning system when the vehicle is switched off. So unless it's being driven in a particularly extreme climate, it doesn't even need topping up. Add one more "win" to the list, then. Extra power, improved real-world fuel economy: Direct water injection enhances efficiency. With direct water injection for turbocharged petrol engines, the BMW Group has again succeeded in enhancing the capabilities of conventional engine technology through an ongoing process of refinement and improvement. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at or near full throttle, while at the same time reducing fuel consumption and emissions.

The 2016 BMW M2 is a steroid-addled M235i [UPDATE]

UPDATE: As it turns out, BMW mixed up the weight specs in the official press materials. We spoke to BMW for confirmation, and the manual M2 weighs 3,450 pounds, the DCT car weighs 3,505. We've updated the text to reflect this. If you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. When we first got behind the wheel of the M235i early last year, BMW was quick to point out the spiritual link between the small quasi-M car and its ancestors, the 2002 Turbo and the E30 M3, but we couldn't help but think fondly of the more potent 1M Coupe. And while the M235i got a lot of things right, its weight and price took some of the shine off it. But more importantly, the intangibles that those older BMWs nailed was somewhat lacking in the M235i – while fun, it was somewhat distant, unlike the visceral 1M. Until we drive the 2016 BMW M2, those intangibles will remain intangible. But on paper, the M2 looks to be a super-M235i, buffed up with M goodies like an active rear differential and lightened suspension components. But if you're looking for a featherweight M235i, you'll be disappointed. The extra power and goodies are offset by negligible weight savings. With the manual it weighs 3,450 pounds, an 85-pound reduction. With the DCT, it's a wash at 3,505 pounds. At least the M2 looks like a proper M car. The side bodywork swells 2.1 inches up front and 3.1 inches in the rear to accommodate wide 19-inch forged wheels wrapped in Michelin Pilot Super Sport tires. The front end takes the M235i theme (itself an adrenaline-injected version of lesser 2 Series cars) and adds steroidal menace, with the expected larger intakes to feed the extra engine radiator. Out back, there's a diffuser in the rear tray that the M235i lacks, and the scallops that incorporate the taillights plainly telegraph the extra rear width. It's the M4's handsome younger sibling. Like the M235i to which its clearly related, the heart of the M2 is a 3.0-liter inline-six that inhales through a TwinScroll exhaust manifold-integrated turbocharger. High-precision direct injection, Double-VANOS, and Valvetronic are all present and accounted for, with some M goodies like pistons and crank bearings trickling down from the M3 and M4. The result is 365 horsepower at 6,500 rpm and 343 pound-feet of torque available from as low as 1,400 rpm.
