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.

BMW predicts US will be biggest i8 market

BMW will be showing a production version of its new i8 plug-in hybrid supercar at the upcoming Frankfurt Motor Show, and while we're quite excited about seeing the company's second i product in the flesh. According to a new report from Automotive News Europe, BMW is expecting its largest markets to be the United States, United Kingdom and Germany. Notable for its absence in that list is everybody's favorite mega-market, China.
Automobilwoche, a German-language publication of Automotive News Europe, spoke with the i8's product manager, Hendrik Wenders, who declared, "The US will be by far the largest sales market for the i8." Wenders stops short of actual mentioning what percentage of i8 sales will be in the US, but does mention that it should arrive in showrooms around the world in about nine months. The simultaneous rollout will occur in 50 different countries.
Check back for our full coverage of the i8's debut at the 2013 Frankfurt Motor Show. If you just can't wait until September, then check out our first drive of the i8 Prototype.

BMW plans range-topping M760i

The rumors have come from several different places throughout the year and they all point to the same thing: we can expect a BMW M760i in 2016 to sit at the top of the 7 Series range. One of the latest scraps of evidence comes from a forum member at Bimmerpost last month who wrote that an M760i would arrive for model year 2017, and it would be the only regular-wheelbase version with a 12-cylinder engine even if a 760i model joins the lineup. The long-wheelbase 760Li, however, would also get a 12-cylinder motor. This week, BMW Blog published what it says is an accidentally leaked image from the German BMW configurator (pictured) that shows an M760i badge. The actual model doesn't appear, but the configurator places the badge over the 7 Series model you choose to configure. This will be the second 7 series to wear an M badge, and whenever we see it, we're told it will get the M Sport Package and Ferric Grey accents. The first M-badged 7 Series was a limited edition for the Middle East sold two years ago. Both the M760Li and 760Li are tipped to use the 6.6-liter V12 found in the Rolls-Royce Ghost and Wraith - that engine being an evolution of the V12 that powered the last-generation 760Li - but their outputs will vary. The long-wheelbase 7 is expected to get 600 horsepower. The M760i is said to get 624 hp, matching the output of the Wraith, and maybe some handling refinements to make it a proper competitor for counterparts from Mercedes-AMG, Audi, and Jaguar. On top of all that there will still be an Alpina B7, rumored to have 600 horses of its own. Introduction of the range could take place at the 2016 Geneva Motor Show.
