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.

2015 BMW 740Ld xDrive

When it first came stateside in 1978, choosing a BMW 7 Series was a simple process. With one engine and one wheelbase, you could just pick what color you want and be on your merry way. Today there are ten different models, forcing drivers to choose among four engines (plus a hybrid), rear- or all-wheel-drive, and two different wheelbase lengths. As if this isn't tricky enough, the options list has more custom choices than the Taco Bell app. Do you want standard paint and upholstery, or something from the pricey BMW Individual collection? What about the headlights: Do you want LEDs, or are the standard xenons just fine? Need a head-up display? Night vision? Adaptive dampers? The list goes on and on. After a week with a new version of BMW's flagship sedan, we've sorted out which model you actually want, although it's still up to you whether or not to order a ceramic-glazed iDrive knob. Our favorite 7 Series is now the 740Ld Xdrive, a conclusion we came to after a week at the helm of the smooth, torquey land yacht. Driving Notes When the diesel 7 first arrived at the 2014 Chicago Auto Show, its engine was already familiar to American consumers. It's the same 3.0-liter, turbodiesel inline-six found in everything from the E90 3 Series to the past two generations of X5, as well as the current 5 Series. A robust 413 pound-feet of torque lathered across the rev range, with peak twist available between 1,500 and 3,000 rpm, and the corresponding horsepower tops out at 255. 0Í–60 happens in a sedate 6.1 seconds, and for those with autobahn dreams the top speed is a modest 130 mph. While those figures aren't terribly impressive, as is often the case with diesels, the real-world application of the engine's power is far more dramatic. Even small throttle inputs produce a smooth surge of acceleration, making the 740Ld feel a lot quicker than the performance metrics might indicate. Even with the current cheap price of gas, the superior fuel efficiency of a diesel engine is worth noting, especially as this model only costs $1500 more than a 740Li xDrive. The diesel tips the scales at nearly 4,700 pounds, yet it boasts a 31-mile-per-gallon highway rating. It's rated at 23 mpg in the city, while our real-world testing saw returns in the mid-to-high 20s. Simple anecdotes about acceleration and fuel economy figures only convey a small part of the 740Ld's goodness.

Fore! Pro golfers race BMW i8 against a golf cart

You wouldn't think a couple of pro golfers racing a golf cart along a nice green course would get the blood pumping. But throw in a BMW i8 plug-in hybrid and things get at least a little more interesting. At least, that's what the German automaker is hoping for. Bimmer is swinging big with a cross-promotional video featuring two pairs of golfers racing plug-in vehicles at the 2014 BMW International Open golf tournament in Koln, Germany. Two of the golfers take your run-of-the-mill golf cart while the other two take a slightly more powerful BMW i8, with the goal to get to the course's "halfway house" first. The race, among other things, sends jackrabbits scurrying and shows off the i8's really cool doors and racy styling. The odd part – "spoiler" alert – is that the golf cart wins the race by taking a short cut through the course despite the fact that the i8 pairs a 231-horsepower turbocharged engine with a 131-horsepower electric motor. It's probably not exactly the message of high-speed performance BMW wants to convey but it would raise eyebrows if this weren't all a silly stunt.
