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.

NHTSA expands new Takata probe to 4 more automakers

DETROIT — The U.S. government's highway safety agency has launched an investigation into four additional automakers that have a potentially deadly type of Takata air bag inflator in their vehicles but have yet to recall them. The National Highway Traffic Safety Administration said in documents posted Thursday that it is investigating Audi, Toyota, Honda and Mitsubishi in connection with a Takata recall involving 1.4 million inflators. This brings the total number of manufacturers potentially impacted to five, as BMW was connected to the issue when it was brought to light earlier in December. The inflators made by the now-bankrupt Takata have a distinct and separate problem that can cause them to blow apart a metal canister and spew shrapnel into people's faces and bodies. The problem killed a driver in Australia who was in an older 3-Series BMW, which has already recalled more than 116,000 vehicles. The problem is so dangerous that in some cases BMW has told drivers to park their vehicles until repairs can be made. The safety agency says in documents that Takata didn't provide details on the affected makes, models or model years of vehicles with the defective inflators. So it is telling the companies to recall them promptly. The agency says that based on when the faulty inflators were produced, it's likely that the vehicles to be recalled came from the 1995 through 2000 model years. In letters to all four automakers, NHTSA says they have five business days to notify the agency after finding out about a safety defect. “If your company has not yet gathered enough evidence to make a determination that the subject air bag inflators present an unreasonable risk to motor vehicle safety, reply with a detailed work plan including the benchmark dates required to make the determination,” the agency wrote in letters to all four automakers dated Wednesday. A Honda spokesman said Thursday it hasn't determined yet whether its vehicles are affected, but a decision should be made soon. Audi, Mitsubishi and Toyota said they are still investigating. NHTSA has told the companies to respond by Jan. 17. On Dec. 4, NHTSA posted documents from Takata and BMW detailing the problems. The documents said the Australian driver was killed, while another Australian driver and a driver in Cyprus were injured. Unlike previous recalls, the Takata non-azide inflators do not use volatile ammonium nitrate to fill the air bags in a crash.

BMW offering glitch fix for i3 with range extender

The BMW i3 has received quite a bit of acclaim since its release, with the electric powertrain grabbing a spot on Ward's 10 Best Engines list and the high-tech machine earning the nod as 2015 Green Car of the Year. However, Consumer Reports uncovered a vexing problem with the range-extended version of the hatchback that has plagued it until a recent software update. While CR was driving the range-extended i3 last year, it discovered that when the internal combustion engine was running during low states of charge, hard acceleration could suddenly cut back with no warning to the driver. This was especially problematic when passing. BMW knew about the issue and promised a software update in the spring. That improvement is now available. BMW spokesperson David Buchko tells Autoblog that the software update adds a percent-of-charge indicator to all models of the i3 to let drivers know just how much juice is left. For the range-extended model, it also provides a warning of possible power reduction when the charge reaches two percent. According to Consumer Reports, the revision lets the car anticipate needing more reserve power based on the topography from the navigation system, as well. For any i3 drivers who want the upgrade, they need to visit a dealer for installation, according to Buchko, but it should be come at no cost to owners. Related Video:
