BMW brings first diesel 7 Series to US with $82,500* 740Ld xDrive

After almost 40 years on the market, there are probably few things the BMW 7 Series hasn't offered, but when it comes to the US market, one of those things just happens to be a diesel engine. That is all about to change, however, as BMW announced that it will unveil the 2014 740Ld xDrive at the Chicago Auto Show before sales commence later in the spring.
Offered only on long-wheelbase models with standard all-wheel drive, the new diesel 7 is powered by BMW's 3.0-liter inline-six producing 255 horsepower and a stout 413 pound-feet of torque peaking between 1,500 and 3,000 rpm. While BMW has yet to release any type of fuel economy figures, it did say that its diesel technology is usually good for an improvement of 25 to 30 percent over the gas models - just for fun, that means that the 740 Ld xDrive could get as much as 24.7 miles per gallon in the city and 36.4 mpg on the highway, but that's just doing the math and there is nothing official behind those numbers. Acceleration will take a little longer than in the 740Li xDrive (shown above) with BMW stating 6.1 seconds from 0-60 compared to 5.4 seconds for the gas model.
Another small increase over the gas version will be in price, with the 740Ld xDrive getting a starting MSRP of $82,500 (*not including $925 for destination), which is just a $1,500 bump over the 740Li xDrive. For comparison, the Audi A8L TDI starts at $78,800, while the previous-gen Mercedes S350 Bluetec was priced at $93,000. Scroll down for more info on the new diesel-powered 7 Series, and stay tuned to our live coverage from Chicago in a couple weeks as we'll have live images and hopefully more info.

Lexus to use BMW 3.0-liter straight-six in next-gen IS sedan?

Here's a rumor so wild it needs a U.S. Fish and Wildlife permit. Japan's Best Car magazine reports that the next-generation Lexus IS will offer BMW's B58 3.0-liter inline-six as one of four powertrain options. That's the same engine found in the new Toyota Supra with 335 horsepower and 365 pound-feet of torque. What's more, the fourth-gen IS will resurrect the IS F model gone AWOL during the current third generation, and do it with the twin-turbo V6 from the Lexus LS 500. The current TTV6 makes the same 416 hp in the LS 500 as the 5.0-liter V8 did in the first Lexus IS F 12 years ago. According to the magazine, the other engine options would be Toyota's 2.0-liter turbocharged four-cylinder, a 2.5-liter for a hybrid model, and a 2.4-liter turbo. We don't know where that last engine fits in. BMW doesn't make a 2.4-liter, and Toyota appears to have retired all of its 2.4-liter applications. Ignoring that, the 3.0-liter straight-six looks like it would replace the current 3.5-liter V6 rated at 311 hp and 280 lb-ft. This wouldn't be the first time the Supra's engine has been ported to the IS. Lexus mavens will remember that two years after the introduction of the original IS in 1998, Lexus put the Supra's 2JZ 3.0-liter straight-six engine in the IS 300 — without the turbochargers, thank you. But Best Car's prediction would have zero relation to history. Those were both Toyota engines back in 2000, and even ignoring the power differential, the IS didn't compete with the Supra. Putting BMW's 3.0-liter in the Z4 and the Supra works because they are the same car. And again, even ignoring the power differential, the more powerful Z4 doesn't compete with the Supra. Best Car's scenario has BMW selling one of its best engines for use in a direct competitor to the 3 Series. Lexus would need to design an engine bay long enough to swallow an inline-six, not a bread-and-butter engine for the brand, yet still be sensible for three more compact powerplants. Then, assuming BMW and Toyota made the same deal as with the Z4 and Supra, the Lexus would be down by a healthy double-digit horsepower margin on its German foe. The new Supra gives up 47 hp to the roadster. Where's the upside? It's said the trim sedan will stay about the same size, on a wheelbase roughly four centimeters longer, but lose a substantial chunk of weight.

Recharge Wrap-up: Houston's bus revival, autonomous trucks on the Autobahn

A documentary shows how Houston, Texas significantly improved its outdated bus system. Called High Frequency: Why Houston is Back on the Bus, the short film describes how the city reimagined its bus system to become more efficient, more useful and more popular. Despite some opposition, the change has proven to be effective, with bus ridership up eight percent in three months, and light rail ridership up due to complementary bus routes. See the video above, and read more at CityLab. Automakers sent autonomous semi trucks on the German Autobahn as part of the European Truck Platooning Challenge of 2016. Mercedes-Benz, Volvo and Scania, among other groups, sent platoons of trucks between Stuttgart, Germany, and Rotterdam, Holland. In Mercedes's platoon of three trucks, the lead truck was fitted with lasers and other sensors to guide the convoy down the road. The two following trucks relied on vehicle-to-vehicle communication to trail 50 feet behind the lead, making room for cars to come between them and closing the gaps when able. The close following distance provides fuel economy gains of up to 10 percent in the rearward trucks on account of the reduction in drag. Read more at Hybrid Cars. Renault has reduced NOx emissions in its Euro 6b diesel vehicles in real world driving conditions. By improving its exhaust gas recirculation systems and NOx traps, nitrogen oxide emissions are cut in half on average, under certain driving conditions. The improvements will be included in vehicles leaving the factory beginning in July of 2016. Beginning in October, owners of Renault Euro 6b diesels can have the modifications added to their cars for free. Read more from Renault. Tata Technologies is creating an innovation lab in California to partner with EV technology companies. Having a tech center in California allows Tata to work on technologies that will largely be deployed in the company's main market of Asia. "Today, we are partnering with companies and startups who have aspirations to sell in China, but a lot of what they do is in California," says Samir Yajnik of Tata Technologies.
