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.

Junkyard Gem: 1982 BMW 633CSi

The E24 6 Series was one of the best-looking cars ever to grace a BMW showroom, and it was the car for successful Californians with a sense of style— whether boardroom heroes or purveyors of not-so-legal substances— to show off their wealth and taste. The E24 is quite collectible now, but the cost of restoration for a worn-out one is so high that many solid examples end up here. I spotted this '82 in a San Francisco Bay Area self-service yard last week. The 3.2-liter straight-six engine in this car was rated at 181 horsepower, which was quite a bit in a year when a new Cadillac Eldorado had just 120hp and a Datsun 280ZX Turbo a mere 180. There wasn't much serious competition in 1982 for a powerful imported luxury coupe with gangsterish overtones. If you were a bent banker treating your savings-and-loan as a personal cash machine in 1982, your mainstream choices were limited to this car, a Mercedes-Benz 380SLC, or a Jaguar XJ-S. For those who hit the big time, the Ferrari 400i and Rolls-Royce Camargue were available... but you'd see a hundred 633CSis for each of those in the wild. What time is it? Time for The Crusher!

Upcoming new Alpina B7 teased

BMW does not make an M7. It never has, despite rumors, trademark filings, and the actual desires of the people that would build such a car. That means that while we're stuck waiting for BMW to see how foolish not building an M is, the most potent 7 Series you can get wears an Alpina badge on the nose. Meet the newest version of that car... sort of. BMW and Alpina haven't taken the wraps off the next B7 just yet, opting instead for an opera-accompanied teaser of the new car undergoing track testing. The car is lightly camouflaged – there's enough to make it clear it's a 7 Series, but not so undisguised as to reveal too much of the Alpina bodywork. There's a more aggressive bumper, a meaty rear spoiler, and sharper side sills, along with what are probably Alpina-specific wheels, but more precise details are hard to discern. What isn't difficult to pick out, though, is ear-tingling exhaust note. The last two Alpina B7s have built on the standard 7 Series' engine, and this new model likely won't be any different. That should mean a breathed upon 4.4-liter, twin-turbocharged V8 which goes well above the unfettled car's 445 horsepower and 480 pound-feet of torque. The extra power, along with the donor car's new lightweight carbon-fiber passenger cell, should make for tantalizing performance capabilities. The current 750i xDrive takes 4.3 seconds to make the sprint, and the B7 model that this new machine will replace hits 62 in 4.6. We'd expect the upcoming B7 will do better. The teaser from BMW and Alpina doesn't indicate when the new model will debut, but we'll eat our proverbial hat if it doesn't happen in Geneva. Related Video:
