BMW M3 driving off cliff is a chilling PSA

We're a little shocked that the unnamed owner of this cliff-diving E46 BMW M3 would upload the in-car footage of his accident to YouTube. Not only that, he uploaded two videos: raw footage of his roll down the cliff (it looks like somewhere in the Southwest, maybe Arizona) and a tribute video for his BMW that suffered the most severe consequences of understeer. Not only does uploading the videos leave him wide open for judgment by fellow enthusiasts (just read the YouTube comments), but we imagine if the police and his insurance company somehow don't know about the incident already, they will shortly. Scroll below to view for yourself.
The raw footage shows the sort of driving that led to the M3's violent tumble, and it serves as a good public service announcement reminder for everyone out there: Just like the Spengler's streams, double yellow lines aren't meant to be crossed. Also, hard driving is one thing, but hammering on public roads at speeds clearly above your skill levels as a driver is not only a recipe for legal trouble, it's a script for ruining your car at the very least, if not your life.

BMW announces M235i xDrive, 7 Series Exclusive among summer upgrades

Like any automaker worth its lug-nuts, BMW is constantly striving to improve its products. And so it has announced a series of upgrades for the summer - none of them revolutionary, but a couple of them notable.
For one, the Bavarian automaker has announced that is is offering xDrive traction on the M235i coupe, a model that has been available until now only in rear-drive configuration. The all-wheel drive version comes with the same 3.0-liter twin-turbo inline-six with 326 horsepower (320 in the US market) and eight-speed automatic transmission as the rear-drive version, but now channels that power to all four wheels for a 0-62 time quoted at 4.6 seconds - two little ticks quicker than the existing version. It's the first time that all-wheel drive is being offered on the 2 Series, and will also be fitted on the convertible - at least, that is, in Europe. We're waiting on confirmation of North American availability.
Among the other announcements is a special edition of BMW's flagship luxury sedan. The 7 Series Exclusive Edition upgrades with metallic paint, 19-inch V-spoke alloys, Nappa leather upholstery and a leather-trimmed instrument panel. Buyers will also be able to opt for the Merino fine grain leather and Alcantara roof lining from the BMW Individual catalog, and choose between any available engine or either wheelbase lengths.

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.
