BMW preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

BMW shows off 245-hp, hydrogen-powered 5 Series GT

With BMW's Innovation Days 2015 underway, the German luxury brand is showing off its latest piece of hydrogen-fuel-cell technology. Based in a 5 Series Gran Turismo, the system Í– co-developed with Toyota – promises to deliver on the promise of zero-emissions motoring, without the lengthy recharge times associated with plug-in electric vehicles. At the heart of BMW's latest FCV prototype is a new electric motor derived from the i sub-brand. It produces the equivalent of 245 horsepower, making it roughly comparable in output to the brand's latest 2.0-liter, turbocharged, four-cylinder gas engines. It draws its fuel from a hydrogen fuel tank that sits between the axles. The BMW-patented storage system can hold enough compressed hydrogen to take the hunchbacked 5 Series 300 miles before refueling. BMW and Toyota first inked their FCV partnership back in 2013, with the goal of having "an initial group of approved components ready by 2020," and sales beginning at some point in the next decade. While Toyota has been touting its successes with hydrogen in the form of the new Mirai, this 5 Series marks the first time since the agreement was signed that the German company rolled out one of its hydrogen-powered cars to the public. Check out the 5 Series GT fuel-cell vehicle in the gallery up top, and then scroll down for the official press release from BMW. Long range, short refuelling times, zero emissions: Hydrogen fuel cell drive system points the way to the future of BMW eDrive technology. As part of its research and predevelopment work in the area of drive technology, the BMW Group has focused on the use of hydrogen as an energy source for more than 30 years now. In 2006 the first luxury sedan for everyday use to be powered by a hydrogen combustion engine was unveiled – the BMW Hydrogen 7. And more than 15 years ago the BMW Group also began to direct its spotlight onto hydrogen fuel cell drive systems. A constant stream of significant advances – in terms of energy efficiency, performance capability and everyday practicality – have likewise been made with this technology, which converts hydrogen into power for an electric drive system, rather than burning it inside the engine. The results of the research and development activities in the field of hydrogen fuel cell drive systems will be presented in driving demonstrations for the first time during the BMW Group Innovation Days 2015.

BMW i3 qualifies for both green and white HOV stickers in California

BMW buyers tend to have enough cash on hand to be buffered from the concept of "sticker shock," but the term may take on a different meaning when it comes to the German automaker's i3 plug-in vehicle and its classification by California clean-air regulators. The first i3 EVs are set to be sold in May, and some are questioning if the new car will be eligible for the state's white stickers or green High-Occupancy Vehicle lane stickers, both of which allow for solo-occupancy in HOV lanes. California gives out white stickers to some types of battery-electric vehicles, compressed natural gas (CNG) vehicles and hydrogen fuel-cell vehicles, and there's currently no limit on the number that can be given out. The green stickers, which are applied to other battery electrics as well as some plug-in hybrids, are limited (there are currently about 15,000 left) and will likely run out within the next year or two. The i3's status is uncertain because of it has an optional gas-powered range-extender. Jacob Harb, head of electric vehicle operations and strategy for BMW, told AutoblogGreen that it's not all that complicated. The pure electric version of the i3 will get the white sticker, the REx version will get the green sticker. He also said that both will qualify for the $2,500 state incentive in California and the $7,500 federal tax credit available in all 50 states (For what it's worth, Green Car Reports says the REx version will only get $1,500 from California).
