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.

Tesla only 8th greenest automaker, BMW is best, says Newsweek

We imagine some readers will be surprised by this. Newsweek has just put out its rankings for the top "green" companies in the world, and while Tesla Motors chief Elon Musk can crow about how green his electric vehicles are, the company as a whole apparently falls behind some traditional automakers. Quite a few of them, actually. In Newsweek's Global 500 list of the greenest 500 largest publicly-traded companies in the world, BMW ranked best among automakers at Number 26. Not surprisingly, Toyota was close behind at 35, while Nissan came in at 152. What's a little more puzzling is that Tesla fell behind Ford (178), and General Motors (289). That's a lot of pickups versus a few Model S EVs. Go figure. Then came Hyundai (306) and Honda (316), which are a little more palatable. Tesla? It came in at 431. Newsweek's measurement standards include eight categories that include a lot of verbiage and involve things like energy productivity (which is defined as revenue in US dollars divided by total energy consumption), greenhouse-gas emissions productivity (revenue divided by GHG emissions), water usage, waste levels and something called "green revenue" (revenue derived from products that "contribute positively" to the environment). Newsweek says that its results are reproducable by a third party. Take a look at the list here and find the details on how the numbers are compiled here.

Editors' Picks June 2023: BMW 3 Series and more luxury sport sedans

This month sees a number of luxury sport sedans gain Editors' Pick status thanks to updated or recently-all-new models coming out. The BMW 3 Series is a longtime favorite, and so is the Alfa Romeo Giulia at this point. Just like the electric version of the G80, though, the gasoline version is also an Editors' Pick this month. In case you missed our 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. The list that youÂ’ll find below consists of every car we rated in May that earned an EditorsÂ’ Pick. 2023 BMW 3 Series 2023 BMW 3 Series View 15 Photos Quick take: The 3 Series may not be the standard anymore, but it's still a superb luxury sport sedan with powerful engines, great handling, impressive tech and tons of space. Score: 7.5 What it competes with: Mercedes-Benz C-Class, Audi A4, Alfa Romeo Giulia, Cadillac CT4, Acura TLX, Lexus IS, Infiniti Q50, Genesis G70, Volvo S60 Pros: Enjoyable and powerful engines; fun handling; lots of space in rear seat and cargo area; attractive design inside and out Cons: Infotainment is frustrating to use sometimes; value isn't the best From the editors: Road Test Editor Zac Palmer — "The 3 Series ticks all the boxes that a top-shelf luxury sport sedan should. It's attractive but not gaudy. The driving dynamics leave me grinning at the end of a fun road, but don't beat me up on the highway. Any and all modern tech is present and accounted for. And while the price is high, it's not so bad for what you get. I'm an especially big fan of the M340i with its inline-six, but the four-cylinder in the 330i is an excellent option if you don't want to spend as much." In-depth analysis: 2023 BMW 3 Series gets fresh styling and infotainment   2023 Genesis G80 2022 Genesis G80 Sport Prestige View 61 Photos Quick take: The G80 has looks to kill, and it backs that design up with a functional and also-gorgeous interior. There's a lot of value to be had with this nice-to-drive luxury sedan.
