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.

Editors' Picks June 2024: Some German SUVs and an excellent sports car

This month sees some recently-refreshed luxury SUVs join the list of Editors' Picks. Both the BMW X5 and Porsche Cayenne are fresh for 2024, and both are extremely tempting luxury performance SUVs for the well-off buyer. The vast array of powertrains available for both of them ensure there's a version for all comers, and any enthusiast would adore the extra-high-performance versions of both. Of course, enthusiasts will enjoy the last car on this month's list the most with the Lotus Emira. It's simply spectacular to drive, and we can't recommend it enough to the hardcore driver. In case you missed previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get an EditorsÂ’ Pick designation. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. You'll find the entire list of Editors' Picks at this link here, which we keep updated as cars are either added or dropped from the list. The vehicles youÂ’ll find below consist of every car we rated in June that earned an EditorsÂ’ Pick. 2024 BMW X5 2024 BMW X5 M Competition View 41 Photos Quick take: The X5 is most desirable in its PHEV and M60i V8 trims, but the whole lineup is extremely competent and brings together excellent performance, excess luxury and cutting-edge tech for its segment. Score: 7.5 What it competes with: Mercedes-Benz GLE, Porsche Cayenne, Range Rover Sport, Maserati Levante, Genesis GV80, Audi Q8 Pros: Superb to drive with knockout powertrains; excellent utility and creative features; styling is sporty and attractive but not over the top Cons: Infotainment system can be a pain; M Competition model is a little over the top; gets pricey quick with options From the editors:  Senior Editor, Electric John Beltz Snyder — "I really like the dual-opening liftgate/tailgate combo. The liftgate portion up top opens quickly, allowing you to throw something inside or grab something out of the back. Flipping down the lower tailgate part gives you a nice place to sit and change shoes. Another benefit is that you can open the liftgate without unsecured items immediately falling out. And with the way the X5 M Competition encourages you to drive it hard, you will end up shifting loose cargo around at some point." Road Test Editor Zac Palmer — "I'd snag the X5 M60i out of all the various X5 variants.

BMW 2 Series specs leaked?

Thanks to spy shots from earlier in the year, we already know what the new BMW 2 Series will look like, but now we know a lot more about the coupe courtesy of an apparent BMW South Africa error and some quick-clicking enthusiasts. Though the information no longer appears to be posted on BMW's South African website, 2addicts.com managed to grab most of the details for the new coupe, including the model lineup, specs and most (if not all) of the options list for the upcoming replacement for the 1 Series.
Just like the latest 3 Series, the 2 Series model lineup starts at the 220i powered by a 2.0-liter inline four-cylinder, but the more exciting BMW figures to be the M235i with its 320-hp, 3.0-liter straight-six. With the automatic transmission, the info says that the M235i weights 3,240 pounds and will be able to accelerate from 0-62 miles per hour in 4.8 seconds - making it both lighter and quicker than the 135is currently offered in the US. The base 220i coupe should also be fun to drive with its 180 horsepower and sub-3,000 pound curb weight.
A quick side-by-side comparison of the dimensions for the base 220i with our current base 128i shows that the new coupe rides on a longer wheelbase (105.9 in. vs. 104.7 in.), is about two inches longer (174.4 in. vs. 172.2 in.) and is an inch wider (69.8 in. vs. 68.8 in.). 2addicts.com even shows available paint colors, interior trim options and lists pricing for South African-spec models. Head on over to the forum to check out all the info they have posted, but we expect the 2 Series to be unveiled at the Detroit Auto Show early next year.
