BMW i3s traction control tech going in all BMW, Mini cars

The BMW i3s is essentially a warmed-up version of the i3 electric car we all know and love. The performance boost isn't huge — just 14 horsepower and 15 pound-feet of torque — but it also gets a new suspension, wheels and tires as well as an improved traction control system. We found the car to benefit from all the updates when we drove it for our First Drive Review, but now BMW has offered up more details on just how the traction control system of the i3s helps make it better to drive. The company says it'll expand the technology to all future BMW and Mini models as well. The i3s's system is calibrated to help it to pull away quickly from a stop, making full use of the instantaneous torque offered by the electric motor. It also improves stability when accelerating out of corners, when using regenerative braking and, of course, when the road conditions are less than ideal. The results are palpable, and with the other improvements the i3s definitely feels stronger off the line, as we found on our drive. It's also about a half-second quicker to 60 miles per hour, at 6.8 seconds. The secret is in the response time of the stability control, which BMW claims is 50 times faster than the conventional system. This is made possible by moving the control process into the powertrain itself, rather than a remote unit. This reduces the signal path and, thus, the response time of the traction control system. BMW's Head of Chassis Development, Peter Langen, said of it, "With their high levels of torque and instantaneous responses to every movement of the accelerator, electric motors already make significantly higher demands on driving stability systems than conventional power units." While engineered to make the most of the electric motor, BMW says the shorter cycles of this traction control system show promise for internal combustion vehicles as well. As such, we'll begin to see the improved technology applied across the BMW and Mini lineups going forward. Related Video:

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 i3 with range extender won't get all the EV tax benefits in NJ

Everyone loves that new-car smell, but not everyone loves that new-car tax. And whoever in New Jersey thought the extended-range version of the BMW i3 plug-in would be exempt from said tax was sorely mistaken, Green Car Reports says. To paraphrase the Garden State's favorite son, Bruce Springsteen, the first kick those drivers will take is when they hit the ground. BMW said last year that the BMW REx would qualify for new-car tax exemptions in New Jersey and in Washington State. The car's all-electric range was recently estimated at 72 miles and it has another 87 miles of gas-powered range-extended capability. Unfortunately, the range extender not only tacks on $3,850 to the car's sticker price but adds on almost that much again because New Jersey's seven-percent sales tax applies to all cars with any sort of gas-powered engine. BMW didn't respond to a request for comment about the New Jersey situation from AutoblogGreen. In other New Jersey electric vehicle news, the Consumer Affairs Committee of the New Jersey State Assembly will discuss the legality of Tesla selling directly to consumbers tomorrow. The extended-range i3 is involved in a different issue on the other side of the country. BMW said earlier this year that the REx would qualify for California's white zero-emission vehicle stickers that allow for solo access to high-occupancy vehicle (HOV) lanes. These unlimited white stickers can go on any EV, but the REx version only qualifies for the green stickers, which are designated for plug-in hybrids and extended-range plug-ins and the state has run out of those.
