BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.

Jaguar Land Rover to drop supercharged V8 for turbocharged BMW power

There are few things that sound as good as Jaguar's 5.0 liter supercharged V8. As great as it is when the supercharger whines or the exhaust cracks and pops on throttle lift-off as the air pressure equalizes, the basic design dates back to the '90s. Plainly, the engine isn't as efficient as it needs to be, but designing a new V8 from the ground up is an expensive proposition. Instead, Automobile reports that Jaguar Land Rover is set to use a twin-turbocharged V8s supplied by BMW. Scalable architecture is all the rage as automakers streamline designs in order to save costs. For example, Jaguar's current supercharged V6 is quite literally a V8 with two holes missing. They didn't even change the length of the block. It seems both of those designs are on their way out, with the V6 being replaced by a inline-six closely related to the company's inline four. It seems that rather than designing an new and expensive V8 for their top of the line models JLR, is sourcing from BMW. From 1994 to 2000, BMW owned Land Rover. A few models, including the Land Rover Range Rover, used BMW engines then and in the initial years of Ford's JLR stewardship. It seems things have now come full circle. BMW currently makes a twin-turbo 4.4 liter V8 that produces anywhere from 440 to 600 horsepower, depending on the application. Automobile says that a new 4.0 liter V8 is in the works and that it will most likely be the engine that JLR uses. Expect it to be more powerful, more fuel efficient, and lighter than what both BMW and JLR currently offer. This seems like a win for both companies. BMW gets to offset the cost of a new motor while JLR, a smaller company, doesn't have to invest in a whole new architecture. As automakers search for ways to cut costs, expect collaborations like this to continue. Infiniti and Mercedes-Benz both share a four-cylinder engine. Ford and GM have worked together to design a shared 10-speed automatic. While we may lament the loss of that wonderful Jaguar Land Rover engine, we can still be happy that they haven't abandoned the V8.

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. 0͖60 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.
