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.

Why are all US-bound BMW i3 EVs with range extenders stuck at port?

The first BMW i3 EVs have been delivered in the US, but in a quirk of the rules, none of them have been the range-extended versions. Long-time BMW electric vehicle driver Tom Moloughney discovered this fact the hard way. His i3 REx has been sitting at a New Jersey port for over a week and he's getting impatient. The problem is something Moloughney calls a "Monroney Hold." So, instead of sitting there fuming, Moloughney did a bit of research and discovered that the problem is something he calls a "Monroney Hold." He says that "the EPA certification has not been completed so BMW doesn't have a Monroney label (window sticker) to post in the window before the car leaves the port, which is required by law. The range extender option changes (shortens) the car's electric range, and also requires an official MPG rating so BMW couldn't use the same Monroney label as they did for the all electric i3." You can read more on his website, but it turns out that the story isn't so simple. For one thing, the EPA testing has been finished. Washington State representative Chad Magendaz told Moloughney that he asked the EPA for an official statement and got the following from Linc Wehrly, Director of the Light-Duty Vehicle Center Compliance Division: "EPA tested the i3 REx and provided the results of that testing to BMW on May 13th. EPA is not aware of anything that would prevent BMW from importing the vehicles since May 13th." Then there's the official word from BMW. Spokesman Dave Buchko told AutoblogGreen that: We are moving as quickly as possible to release the first BMW i3 Range-Extender models to BMW i Centers. Receipt of test data from the EPA is one step, but not the final step, in the process of receiving certification from the EPA. Rules do not permit the release of vehicles for sale until EPA labels are finalized, produced and affixed to any vehicle. Barring any unforeseen delays, we expect that to happen by the end of this week. We have never certified a vehicle like this before. We are taking every precaution to make sure that everything is done in a timely, but more importantly correct manner. In that Monroney labels cannot be produced until the EPA certification process is complete, the characterization [of a "Monroney Hold"] is not technically incorrect, but there is more to it than that, as is often true in life. On a lighter note, BMW donated a loaded i3 to Brad Pitt's Make It Right charity foundation as a fundraiser. Read about that below.

BMW can't build enough M3 wagons, but the U.S. won't see any

Why, oh why, won’t the automobile companies that supposedly cater to Americans give us a viable touring wagon? Seems that BMW is one manufacturer thatÂ’s aware of the question, but skirts the answer. WhatÂ’s more frustrating is that the German company, and others, have for years been off-handedly tossing out the same refrain: “Maybe weÂ’ll bring a wagon back to the U.S.” Not. All the more irritating then is the news that the Bavarians have increased production in Munich of its M3 Touring longroof version to keep up with demand. The information comes via Bimmer Today, which spoke with BMW M CEO Frank van Meel. He said that the company was surprised by the amount of interest in the M3 Touring since its debut during last year's Goodwood Festival of Speed. In fact, he said, the company had to facilitate a production ramp-up within its Munich facility. Despite that increased production, the backlog of orders means that customers are still on wait lists, he said. Last year, van Peel admitted that demand for M-wagons in the U.S. has been steadily increasing, and exporting a touring example was a concept BMW was "taking into consideration.” Crossovers certainly are this decadeÂ’s version of the wagon, which leaves American enthusiasts will few choices: only expensive versions from Audi, Volvo and Mercedes-Benz and a couple of others. Details that were announced last year — a few months before the wagon went into production for sale in Europe, the U.K. and elsewhere — noted that the M3 Touring was only available in Competition spec with xDrive all-wheel drive and a 3.0-liter twin-turbo inline-six with 503 horsepower and 479 pound-feet of torque. Pricing started at GBP80,550 ($105,000 U.S.) More data on the M3Â’s intro here. Related video:
