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 Hardtop's next generation could be smaller, electric-only

Mini has started developing the fourth-generation Hardtop it will release in the early 2020s. Many aspects of the car aren't set in stone yet, but the company's chief executive revealed his team is considering making the hatchback smaller than the current model by offering it only as an electric car. The cheeky Hardtop has ballooned in size since the first-generation model arrived in 2000. The current, two-door variant of the car (pictured) is eight inches longer, two inches taller, and about 250 pounds heavier than the original BMW-developed hatchback. Company boss Bernd Koerber told British magazine Auto Express that he's pushing his team to make the next Mini small again. Going electric-only would allow engineers to get close to the original Hardtop's footprint. An electric motor is more compact than a comparable gasoline-powered engine, and the battery pack can be cleverly integrated in a part of the car that doesn't extend its length. Whether Mini will manage to integrate a bulky battery pack into the Hardtop while shaving 250 pounds remains to be seen. "I would love to see Mini move back to the essence of clever use of space. That means the outer proportions on the core Mini Hardtop could be reduced. I can see that happening," Koerber explained. He added shrinking the hatchback wouldn't make it less practical. Auto Express speculated Mini might sell the current, third-generation Hardtop alongside its replacement for several years to satisfy motorists not interested in going electric. This strategy will become increasingly common during the 2020s; the Fiat 500 will soldier on in Europe after the launch of its battery-powered successor, and Porsche confirmed it will manufacture the first- and second-generation variants of the Macan side by side to give customers exactly what they're looking for. Going electric-only wouldn't be the cheapest, easiest way to replace the Hardtop. The firm can't use the BMW-sourced platform that underpins the recently-released Cooper SE because it's too big, so it would need to develop a new architecture specifically for it. Engineers would also need to figure out how to develop an electric follow-up to the John Cooper Works-badged hot hatch. None of these problems are insurmountable, but they're expensive to solve, so Mini's executives are giving themselves time to weigh the pros and cons of reinventing the heritage-laced British icon yet again.

Mini launches electric conversion program for classic models

Mini unveiled an electric version of one of its classic models at the 2018 New York Auto Show. While the project was billed as a one-off at the time, the BMW-owned company announced it will begin making the conversion available to customers through a program called Recharged. Details about what's involved in the build are few and far between, beyond the obvious: The engine and transmission (which form one unit on these cars), the exhaust system, and the fuel tank are removed to make space for an electric motor, a battery pack, and the required electronics. The drivetrain is rated at 120 horsepower, which is nearly twice the 63-horse output of the final Mini models built in 2000, but the battery seemingly adds a tremendous amount of weight because performance isn't as impressive as you might think. Mini pegs the 0-to-60-mph time at 9 seconds (around 5 seconds less than a 2000 car), and it quotes 100 miles of range — 14 less than the Cooper SE. Several subtle visual details set the Recharged apart from a regular Mini. Look closely and you'll spot the Cooper SE's logo on the hood, on the trunk lid, and on the center caps. Some of the cars pictured in Mini's gallery also feature this logo on the quarter panels. Inside, there's a new-look analog instrument cluster, which — to Mini's credit — keeps a relatively period-correct design. It includes a speedometer, a temperature gauge, a range gauge, and a gauge that tells drivers which gear they're in. Speaking of, there's no longer a need for owners to argue about the merits of "magic wand," remote-shift, and rod-change gearboxes: The Recharged is exclusively offered with an automatic. Luckily, Mini isn't completely discarding its heritage. It stresses that all of the changes made during the EV conversion are reversible, and that the drivetrain that's removed from the car is labeled and stored in case the owner chooses to make the car original again. Pricing for the conversion hasn't been announced yet. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
