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 M2, we're happy to see you

I recently spent some time behind the wheel of the BMW M235i and, well, I didn't love it. Sure, it's a great car, but I just didn't truly bond with it the way I have with previous M cars. What I had hoped for was a proper successor to the 1 Series M Coupe I fell in love with in 2011, but what I got instead was just a sporty 2 Series that didn't exactly stir my emotions in the same way.
But now there's this: the honest-to-goodness BMW M2. Previously, spy photographers captured a development-mule M2, but this is the real thing, in its full prototype body. Notice the aggressive front fascia that mimics the M3/M4, the more more robust wheel/tire package, and the M-standard quad exhaust outlets around back. This thing sure does look the business.
Details are slim as of this writing, but rumors suggest power will come from BMW's now-ubiquitous N55 turbocharged 3.0-liter six, with output somewhere in the 360- to 380-horspower range. The seven-speed M dual-clutch transmission seems like a good fit here, too. As does a six-speed manual transmission (here's hoping).

The Bilenkin Vintage is a retro-Russian coachbuilt BMW

If you want to add some retro Russian style to your E92 BMW 3 Series, the coachbuilt Vintage by Bilenkin Classic Cars is probably your best (and only) option. The coupe's shape takes inspiration from vehicles of the Communist era, but this bespoke machine's design gets even crazier on the inside. The company's website shows that Bilenkin already has experience restoring classic cars, but this design. That experience is on display here. The stylists do a masterful job of hiding the BMW donor at the front, and the two big headlights and low-mounted, chrome bumper seem to take inspiration from old Volgas. In a fantastic touch, lengths of chrome also run through the door handles down the side to accentuate the rear. The back might be the styling's best angle because of the way the fins step down over two tiers to create the taillights. While the exterior focuses on mixing vintage looks with modern underpinnings, the interior cossets the occupants in opulent trim that features gold and diamonds. Bilenkin upholsters one example in its photos (above right) with paisley fabric, teal trim, and a frosted gearshift. The company also has one with a more traditional look that combines brown leather, wood, and crimson carpets. The Vintage recently debuted at the 2015 Dubai International Motor Show, but Bilenkin doesn't go into much detail about the vehicle's mechanical specs. According to the company's site, "it is intended to embody elegance and style along with the principle 'Sheer Driving Pleasure.'" The retro design certainly achieves the first part of that goal, while the BMW bones probably deliver the latter as well.
