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:

Mini Electric Pacesetter will lead Formula E, hints at future JCW cars

Just a few days ago, Mini teased a wild electric hatchback with pace car-style lights. And just as we expected, it's the new safety car for Formula E. It's called the Mini Electric Pacesetter inspired by JCW, which is a mighty long name for such a little car. It looks like a blast, and although it's not exactly a production car or the direct forebear of a car that will be offered, it does hint that there will be high-performance electric Minis. Don't just take it from us, take it from the man in charge of Mini, Bernd Korber: "But it does reveal one of the directions we could take with the electrification of the JCW brand. For me, the message is clear: Electrification and John Cooper Works are a good fit." Mini made some major modifications to the Pacesetter to get it ready to lead race cars. It weighs 287 pounds less than the Mini Cooper SE that it's based on, giving it a total weight of 2,712 pounds. Much of that weight loss comes from the gutted interior, which now has a welded-in roll cage, race seats and six-point harnesses. While not particularly related to weight saving, the seats also have a neat 3D-printed material for the cushions that can be made in different colors and densities. The electric motor and battery are unchanged at 181 horsepower and 199 pound-feet of torque, but the weight loss means that it hits 62 mph in 6.7 seconds, an improvement of 0.6 over the road car. Handling and braking are upgraded with racing coilovers that have adjustments for compression, rebound, camber and ride height, as well as four-piston brake calipers. Mini John Cooper Works GP forged four-spoke wheels are fitted with 245-mm Michelin Pilot Sport tires. The wider track from the wheels necessitated the unique 3D-printed carbon fiber fender flares. The rear wing, which is similar but not identical to the GP unit, is also made of 3D-printed carbon fiber material. Splitters, side skirts and a large rear diffuser round out the aerodynamic tweaks. The car will make its racing debut at the Formula E event in Rome on April 10. And we hope we won't have to wait too long for an electric John Cooper Works model to reach the public.

The electric Mini SE crushes its EPA range estimate in our real-world test

The range meter of my fully charged 2020 Mini Cooper SE reads 110 miles as I fasten my seatbelt, which is hardly a surprise because that number matches the official EPA-certified range of this all-new electric car. But then I turn on the climate control system, at which point the range prediction promptly falls to 103 miles. “Uh-oh. This could get interesting,” I say to myself. My range test course, you see, is a vast loop that measures about 105 miles around. I donÂ’t really think IÂ’ll end up walking, though. I remind myself that most electric cars IÂ’ve tested — the Porsche Taycan among them — routinely outperform their rated range. But “most” is the operative word in this train of thought, so I ease out of my driveway to begin the test under a tiny cloud of uncertainty. Will the Mini Cooper SE prove to be one of the outliers? Will I encounter any low battery warnings? All will become clear in the next three and half hours. None of my initial hand-wringing should be taken to mean the MiniÂ’s rated range of 110 miles is somehow insufficient. ItÂ’s not, in my view. The length of my course has no special meaning. It doesnÂ’t represent the “right” number of miles. How the test was run My loop in Orange County, Calif., represents what I call typical suburban city driving. ItÂ’s not as dense as the notorious gridlocked areas found in West Los Angeles or certain big-city downtown environs, so itÂ’s applicable to the vast majority of drivers. It features suburban residential and arterial streets, with speed limits that range from 25 mph to as much as 60 mph. But thereÂ’s no pure freeway mileage, and the entire route is peppered with more than 310 signals. As for elevation, it ranges from sea level to just over 600 feet. I run with the automatic climate control system set within the range of 72 to 75 degrees, aiming to settle on one specific setting throughout that delivers adequate comfort. IÂ’ll try whatever Eco drive mode there is, but if throttle response is anemic IÂ’ll use the normal setting. Here, the default mode is the “green” mode, and IÂ’m sticking with it because the SEÂ’s driveability is totally agreeable. As for speed, IÂ’m running mid-pack between the leadfoots and the slowpokes. I wonÂ’t try to out-drag anyone leaving signals, and I look far enough ahead that I can choose the best lane and anticipate when the next signal is going to change. In short, IÂ’m aiming to land halfway between hypermiling and hyperactive.
