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.

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.

BMW 2 Series gets 3-cylinder Mini engine

BMW just keeps lopping off cylinders from its engines and sliding the ever-more-diminutive mills into its models. This spring, Europeans will get some of the automaker's smallest yet thanks to a new entry-level 2 Series that will share a powerplant with the Mini Cooper. The Bavarian company will also introduce a few other tweaks to the compact coupe across the pond. The 218i is the new 2 Series base model, and it shares its 1.5-liter turbocharged three-cylinder with the latest family of Minis. The engine makes the same 134 horsepower and 162 pound-feet of torque, but BMW does have some tiny changes for it. First, the orientation is swapped to fit lengthwise under the hood and drive the rear wheels. Just as importantly, buyers can order it with an eight-speed automatic, rather than the six-speed in the Minis. BMW claims that the little engine gives the 218i a 50:50 weight distribution, and it takes around 8.8 seconds to reach 62 miles per hour with the standard six-speed manual – tack on another tenth for the automatic. Either way, top speed is still a perfectly respectable 132 mph. Those acceleration numbers, incidentally, are over a second slower than what the latest Cooper is quoted at. Beyond this new base model, BMW will bring a few other additions to the 2 Series for Europe. The 220d oil burner will be available with xDrive all-wheel drive, and the company will introduce several new equipment bundles called Advantage, Luxury Line, Sport Line and M Sport. Each will bundle various options and trims together to appeal to buyers. No word yet on whether the 218i will eventually make it to North America, but we aren't holding our breath. Scroll down to read BMW's lengthy release about all of the changes set for the 2 Series. The BMW 2 Series Coupe: New entry-level engines, new model variants, even greater individuality. Premiere of the BMW 218i Coupe with 3-cylinder petrol engine from the new BMW Group engine portfolio and the BMW 220d xDrive Coupe – new and varied range of equipment features for model variants Advantage, Sport Line, Luxury Line and M Sport. Munich. From March 2015, new entry-level engines, a further four-wheel drive model and additional equipment options will increase the diversity of features available for the BMW 2 Series Coupe. With the market launch of the new BMW 218i Coupe, a three-cylinder petrol engine from the BMW Group's latest engine family will be featured for the first time in the brand's sporty and elegant compact model.
