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.

2017 BMW Alpina B7 xDrive is an M7 by any other name

Have you been waiting for BMW to release a more potent version of the new 7 Series? Try 600 horsepower on for size and forget all about the famous M badge. The new flagship performance sedan from Munich is the 2017 BMW Alpina B7 xDrive. Alpina is Bimmer's tuner of choice, and it designs customized features to integrate precisely with the factory build. The B7's 4.4-liter twin-turbocharged V8 is massaged to deliver a nice, round 600 horsepower, and a torque figure nearly as impressive at 590 pound-feet available from just 3,000 rpm. All that muscle is channeled through an eight-speed automatic to all four wheels (as you might have guessed from the new xDrive handle). The result is an Autobahn-blitzing 0-60 time quoted at just 3.6 seconds – 0.8 seconds quicker than its predecessor – and a top speed estimated at 193 miles per hour. Those would have been considered supercar figures not that long ago, but are delivered here in a luxury sedan as big as they come. They also stand up pretty well to the forced-induction eight-cylinder competition in the Audi S8 Plus, Jaguar XJR, Maserati Quattroporte GTS, and Mercedes-AMG S63. The Audi produces a bit more power but less torque, the Mercedes does the opposite, and the Jaguar and Maserati are left in the dust. Only the S8 Plus dares claim a quicker 0-60 time, and even then it's only said to be a tenth quicker. (The Mercedes-AMG S65 boasts much higher output from its V12, but without an all-wheel drive system capable of handling all its muscle, it's a fair bit slower off the line.) Keeping all that momentum under control is an air suspension with adaptive dampers, active roll bars, and four-wheel steering. It's all mounted to 20-inch wheels wearing Michelin Pilot Super Sport rubber and packing oversized brakes measuring 15.5 inches at the front (with four-piston fixed calipers) and 14.5 inches (with floating calipers) at the back. Of course it also benefits from all the advancements that the Bavarian automaker developed for the latest 7 Series, but takes things a step further with a specific aero kit and an interior decked out in even more upscale leather and trim. The finished product may not wear an M7 badge as so many have called for from BMW's flagship sedan series over the years. But the Alpina name carries a cachet all its own and has for the past 50 years now – which is a few years longer than BMW M GmbH has been around.

Land Rover could build a baby Defender on a platform sourced from BMW

The collaboration between BMW and Jaguar-Land Rover started out small, it was originally limited to motors for electric cars, but it might not stay that way for long. The Tata-owned British sister companies will allegedly rummage through Munich's sizable parts bin to build nearly half a dozen cars scheduled to come out during the 2020s. According to a report by British magazine Autocar, Jaguar has started designing two small cars that will join its growing family of Pace-badged soft-roaders. They'll be new additions to the firm's portfolio, not replacements for existing cars. One will be a regular crossover, while the other will be a swoopier, form-over-function four-door model ostensibly marketed as a coupe. Both will slot at the very bottom of the Jaguar portfolio, below the already pretty small E-Pace, in a growing market segment where the competition is fierce, and profit margins are thinner than an i3's tires. Here's where BMW apparently comes in. Instead of developing a platform from scratch, the two crossovers could ride on the hybrid-ready, front-wheel drive FAAR architecture found under the third-generation 1 Series hatchback and the upcoming 2 Series Gran Coupe. If we believe an earlier report claiming Jaguar and BMW will also share engines, most of the hardware found under the sheet metal will have German genes. All-wheel drive will certainly be available, and it could also come from BMW. The same platform -- and, presumably, the same engines -- would provide the basis for a Land Rover-badged model positioned in the same segment. Autocar learned it will be to the next-generation Defender (pictured) what the Mercedes-Benz GLB is to the G-Class. Some key design cues will carry over, but the two models will share absolutely nothing under the sheet metal. The soft-roader could resurrect the Freelander nameplate when it goes on sale during the 2020s. Looking even further ahead, the front-wheel-drive platform the next Mini Countryman and X1 will utilize could find its way under the replacements for the next Range Rover Evoque and Discovery Sport. These plans could very well change; the Evoque and the Disco Sport barely entered their second generation, so they're not due for a replacement until the second half of the coming decade. While neither company has confirmed or denied the report, the partnership makes sense from a business standpoint.
