BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed

The BMW specialists at Alpina know how to exploit a niche when they see one. With the BMW M4 still not technically official, it saw the need for a higher performance four-seat convertible than the 435i 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the Geneva Motor Show.
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).

Mini may not build electric cars in England due to Brexit

BMW will decide whether to build its new electric Mini in Britain or elsewhere by the end of September, its board member for sales told Reuters, in a test of the country's ability to continue to attract investment as it leaves the EU. Mini makes around 70 percent of its approximately 360,000 compact cars at its Oxford plant in southern England but the car industry is concerned about the effect any loss of unfettered access to the EU, its largest export market, could have on plants after Brexit. BMW is deciding between its English site, a plant in the Netherlands where it has built more of its conventional line-up in recent years, and its Germany plants at Leipzig and Regensburg for the new low-emissions variant. The firm's board member for sales told Reuters that the electric Mini investment, likely to be worth tens of millions of pounds, would come in the next three months and the board was currently considering a number of factors including Brexit. "One of the elements is what is the likelihood of a tax regime and if there's a tax regime, how would it apply," Ian Robertson said during an interview at the Goodwood Festival of Speed in southern England. "If you made the motor in a German plant and you then assembled the car in a British plant, and you took the cars back to the German market, then the duty that you would pay would be reclaimed," he said, in an example of the options companies are examining to plan for any duties or tariffs. The automaker is also looking into where the uptake of greener models is strongest and where the best supply chains are, he said. Britain could approve its first major electric battery hub in the next few weeks after officials in central England submitted proposals to ministers in May. But last month, the car industry issued its strongest warning yet on the need for politicians to strike a transitional Brexit deal after two-year talks to ensure unfettered trade is maintained. Uncertainty has also been heightened after a snap June 8 election which left Prime Minister Theresa May without a majority and has led to ministers in her administration hinting at different versions of Britain's likely post-Brexit future. Last year, May's administration helped secure two new models at Japanese carmaker Nissan's plant in the north of England after what a source said was a government promise of extra support to counter any loss of competitiveness caused by Brexit.
