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.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.

U.S. tariff threat hits European automakers' stocks

FRANKFURT, Germany — A U.S. warning that it may introduce tariffs on foreign auto imports hit shares in German carmakers BMW, Daimler and Volkswagen on Thursday, which together have a more than 90 percent share of North America's premium car market. Washington said on Wednesday it had launched an investigation into whether car and truck imports are a national security issue due to signs they had damaged the U.S. auto industry. That could lead to new U.S. tariffs — up to 25 percent — similar to those imposed on imported steel and aluminum in March. BMW and Daimler shares fell as much as 3.1 percent in early Thursday trading, while Volkswagen's dropped as much as 2.5 percent. "(U.S. President) Donald Trump is obviously not thinking about how to prevent a trade war. Import duties on cars would be a nightmare for the German auto industry and would lead to a massive sales impact," said Thomas Altmann at Frankfurt-based asset manager QC Partners. BMW on Thursday condemned the move to consider tariffs. "The BMW Group is committed to free trade worldwide. Barrier-free access to markets is therefore a key factor not only for our business model, but also for growth welfare and employment throughout the global economy," it said. Daimler, which makes Mercedes-Benz cars, and Volkswagen, which makes upmarket Audis and Porsches, were not immediately available for comment. German carmakers produced 804,000 cars at local factories in the United States and exported 657,000 German-made cars into North America last year, according to German auto industry association VDA. China took pains on Thursday to welcome German firms and investments, with Premier Li Keqiang talking up relations after a meeting with German Chancellor Angela Merkel. BMW and Mercedes have expanded production capacity in the United States, but BMW, Audi, Volkswagen and Daimler have also invested billions to build new factories in Mexico in the hope of selling locally produced cars into the United States. German carmakers hiked vehicle production in Mexico by 46 percent to 620,000 cars last year, while production levels inside the United States fell by 6 percent to 804,000 cars because of a shift to Mexico, according to the VDA. BMW has its biggest factory worldwide in Spartanburg, South Carolina, and is the largest vehicle exporter among all the carmakers in the United States measured by value of goods exported. More than 70 percent of BMW's U.S.-made cars are exported.
