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. The facilities are part of joint ventures with the city of Tianjin and State Research Information Technology (SRIT). In addition to investments of over $190 million from SRIT and Teamsun, NEVS has received $1.6 billion in credit from the Bank of China to develop its business there. The new Tianjin factory will have a capacity of 200,000 new energy vehicles per year. The facility in Trollhattan, Sweden will provide manufacturing planning, training, and product supply for the Tianjin plant. Read more at Green Car Congress, and in the press release from NEVS. 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. Read more about the plant and the production process the press release below. NEW ELECTRIC MOTOR STRENGTHENS POWERTRAIN EXPERTISE AT CLEON ZOE's new electric motor, unveiled at the Geneva Motor Show, is a 100% Renault motor manufactured at the French site of Cleon, already specialized in highly technical powertrain production. Until now, the flagship of the Cleon plant was the Energy dCi (130, 140, 160) internal-combustion engine. The diesel unit with advanced technological content has made a name for itself at Groupe Renault, the Alliance and with our partners.

2014 BMW 328d ready to burn oil in just four cylinders

Despite showing off the new 328d sedan in New Jersey yesterday, BMW though it only fair to bring the first four-cylinder diesel it will ever sell in the US to the New York Auto Show today as well. Unfortunately, the company remains vague about pertinent details like fuel economy and price, but we did hear again that the oil-burner will be capable of getting 45 miles per gallon on the highway. BMW's Oliver Ganser told AutoblogGreen, "We do not want to give out" the city or combined mpg ratings quite yet, but The New York Times got someone to estimate a fuel economy of mid-30s in the city.
The two-liter TwinPower turbocharged and direct injected engine and eight-speed automatic transmission (sorry, no manual will be available) put out 180 horsepower and 280 pound-feet of torque and should get the 328d up to 60 miles per hour in just over seven seconds. As we noted earlier, the 328d will be available with every option and trim level - like all-wheel drive - that other 3 Series models have in the US (transmission excepted) and should start at under $40,000 when it goes on sale this fall.
Officially, the 328b will be able to accept biodiesel blends up to B5 (or, just maybe B7), which is standard diesel with five (seven) percent biofuel. Read more about that and other aspects of the 328d here.

BMW replaces tri-turbo diesel with a quad turbo

Quad turbos have until now been the stuff of Bugattis. BMW is introducing a quad turbo diesel for the 7 Series, with nearly one hundred horsepower per turbo. It's all about making the six-cylinder 3.0-liter turbodiesel all as enticing a proposition as possible, and it faces strong competition from Audi's new twin-turbo V8 diesel available in the SQ7 TDI. The earlier, N57S engine (pictured above) utilized a triple-turbo setup good for 381 horsepower and 546 lb-ft. The new B57 version, confirmed by BMW at the 37th International Vienna Motor Symposium, adds yet another turbo for 394 hp and 561 lb-ft, and that massive torque is available from 2,000 to 3,000 rpm. It means the 7 Series gets from 0-60 mph in a snappy 4.5 seconds. The engine could produce even more torque, but 561 lb-ft is all the ZF 8HP 8-speed automatic transmission can handle. The N57S engine's dual-stage turbocharging setup consisted of one low-pressure turbocharger to take care of low-end torque, and two high-pressure turbos for the higher rev range. In the new B57 engine, the big turbo is now replaced with two smaller units on a common exhaust, to benefit from lower costs and smaller unit weight. In addition to the gains in power and torque, fuel economy has reportedly been improved by 5 percent. There are no reports yet whether the B57 TOP quad-turbo will make it to the US market, but customers in the European high end diesel saloon market will probably be very excited. Initially it will be available in the 750d xDrive version, and other top-end models like the 5 Series and the X5 will follow later on.
