Recharge Wrap-up: Renault's electric motors, BMW i3 is AM free

Why isn't AM radio offered in the BMW i3? Some drivers – particularly those interested in local traffic reports – have noticed its absence. BMW says that the electromagnetic interference from the electric drivetrain caused poor performance, and that while reception wasn't always terrible, it wasn't up to their standards. Rather than have customers complain to their dealers, who would be unable to do anything for them, BMW has disabled AM reception in the i3. Some customers have hacked their cars in order to enable the AM radio, despite possible warranty issues, and have found the reception to be acceptable. Read more at Green Car Reports. Saab's current parent company, National Electric Vehicle Sweden (NEVS), broke ground for production and R&D facilities in Tianjin, China.

Renault is building the new R240 electric motor for the Zoe at its Cleon plant. The plant and its employees, which specialize in the Energy dCi diesel engine, have adapted to produce high volumes of the electric motor as well, including a 6,000 hours of training for the staff and millions of dollars in investments. "We aim to become the leading powertrain plant for the Alliance," says Cleon plant director Mendi Ammad. The plant is capable of producing 50,000 units of the R240 motor per year, with that number expected to double in the future.

Evo pits BMW M3 against Porsche Macan in drag battle

If you want to move five passengers in very rapid fashion and you've got a $75,000 budget, two newly introduced four-door models immediately come to mind - both are the highest performing vehicles in their respective segments. But which is faster off the line, to the 60-mile-per-hour benchmark or flat-out over an even longer run? Evo took both to paved aircraft runway to find out.
In lane one we've got the all-new Porsche Macan Turbo, which boasts a twin-turbocharged, 3.6-liter V6 rated at 400 horsepower and 406 pound-feet of torque. The Porsche is fitted with a seven-speed, dual-clutch gearbox, and the 4,244-pound crossover has the traction advantage of standard all-wheel drive. In lane two is the all-new BMW M3, powered by a twin-turbo 3.0-liter inline-six rated at 425 horsepower and 406 pound-feet of torque. It is also equipped with a seven-speed, dual-clutch gearbox, but only the rear wheels of the 3,595-pound sedan are driven. Both the BMW and Porsche arrive with launch control, which helps to remove driver error off the line.
Which automaker's launch control system is better off the line? Does all-wheel-drive grip give the crossover the advantage it needs to overcome its adversary's power-to-weight advantage? Will aerodynamics factor into the results? Which would you put in your garage, and why? The video may surprise you.

Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.
