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:

2014 Mini Cooper

If I had a dollar for every time I heard someone from Mini refer to 'go-kart-like handling,' I'd be retired, living on a beautiful piece of coastline somewhere in the Caribbean. Perhaps even on the shores of Puerto Rico, where Mini chose to launch its latest Cooper and Cooper S hatchbacks. As with so many frequently used phrases, though, there is indeed some truth to the cliché - while the Mini Cooper has never actually handled quite like a go kart, it has always had a certain directness in its movements, reacting to steering inputs with an immediacy and fervor unlike most any other automobile meant primarily for the street.
Combine those unique driving dynamics with a sense of fun that permeates the entire brand from pre-sales marketing to the actual sales process itself and you end up with a marketplace success. As an ex-Mini owner myself (a 2009 Cooper S Convertible), I can attest to the kinship felt between fellow Mini drivers who share in the knowledge that they are having more fun than the poor appliance-driving masses sharing the highways and byways of these United States. It's no surprise that the style-conscious US continues to be the marque's single largest market year after year.
This enviable brand perception hasn't been attained without its own fair share of flaws, however. Though the quirky design and massively customizable bits and pieces that have made up the Mini brand's interior philosophy since it was reborn in 2001 have proven somewhat endearing, the Cooper Hardtop's ergonomics have always been an unmitigated disaster. Plus, this is a very small car, with a rear seat that's practically uninhabitable by adult-size occupants. While that adjective seemingly goes hand-in-hand with the brand's name, the modern Cooper has never been as ingeniously packaged as its 1959 forbearer, which offered up as much interior space as possible through innovative engineering and minimalist design. Further, parent company BMW has positioned Mini as a premium brand, so the Cooper's diminutive size has never equated to low prices. And for being such a small car, the Cooper historically hasn't been well-known for its fuel efficiency.

David Brown's most powerful Mini Remastered has racing in its genes

David Brown Automotive detailed its latest Remastered build, which explores the Mini's vast racing heritage. Created jointly with Oselli, the resto-modded city car gains a more powerful engine, a long list of updates that racers in the 1960s could only dream of, and a handful of styling tweaks that set it apart from an unmodified Mini. Most of David Brown's builds have focused on adding luxury, comfort, and convenience to one of England's best-known cars. With decades of experience in building race cars, Oselli brings a healthy dose of performance. The transformation starts under the hood, where power comes from a twin-carbureted, 1.5-liter four-cylinder tuned to develop 125 horsepower and 113 pound-feet of torque. David Brown quotes a 7.8-second sprint to 62 mph. Context is useful: the original Mini retired in 2000 with a fuel-injected, 1.3-liter version of this engine (called A Series) rated at 62 horsepower and 70 pound-feet of torque. Many examples built in the 1960s and the 1970s got an 848cc four rated at a measly 34 horsepower, and the modern-day Hardtop's entry-level engine is a 1.5-liter turbocharged triple that puts 134 horses under the driver's right foot. Put another way, 125 is a lot of horsepower for an old Mini. Oselli dropped the 1.5-liter engine on top of (and not next to; it's one of the Mini's quirks) a redesigned five-speed manual transmission that spins the front wheels. AP Racing four-piston front brake calipers and aluminum rear drums keep the power in check, while Bilstein struts amplify the go-kart like handling the old Mini is known for. Subtlety isn't part of the Oselli's vocabulary. Its free-flowing exhaust system makes it louder than a standard Mini, and it turns heads with black exterior accents, racing stripes, LED headlights, and a mesh grille with integrated driving lights. 13-inch alloy wheels come standard; they're available in either graphite or gold. Inside, David Brown added sport seats for the front passengers, an Alcantara-upholstered Sabelt steering wheel, and a Pioneer infotainment system with Bluetooth connectivity. Power steering, USB ports, air conditioning (which, oddly, blows through vents that look like they're from a Mercedes-Benz), and power-operated windows are standard.  David Brown will make only 60 numbered units of the Oselli Edition, and deliveries are scheduled to start in early 2022.
