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.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

BMW readies EV, hydrogen updates for 2015 Detroit Auto Show

BMW's stand at the 2015 Detroit Auto Show will be the place to go for updates. News about advances in electric vehicle infrastructure, hydrogen fuel cells (maybe) and BMW's suite of connected vehicles app things will all make an appearance at the show next month. Let's start with what we know for sure. Both the i3 and i8 plug-in vehicles are supremely connected cars. A new announcement from BMW (available below) says that the suite of "Now" – ChargeNow, ParkNow and DriveNow – apps will be extended and available internationally. The updates include things like being able to find new new fast-charging stations and ParkNow LongTerm, which will let drivers find a permanent parking space where they can fill up their batteries. As Jacob Harb, BMW of North America's head of electric vehicle sales and strategy, told AutoGuide, "2015 is the year of infrastructure." While there is no official mention of a fuel cell stack in the official release (and we've asked BMW to see if there's anything to this news), Inside EVs says that BMW will also show off its new fuel cell stack in Detroit. That's the one that Toyota and BMW are working on together, as announced back in January 2013. If it makes an appearance, then it'll be our first look at the powertrain that's one generation beyond what Toyota has now in the Mirai. BMW at the North American International Auto Show (NAIAS) 2015 in Detroit. On 12 January 2015, BMW will welcome in the new car year by unveiling a raft of new products at the North American International Auto Show (NAIAS) in Detroit. A fixture on the calendar since 1907, the event originally known as the Detroit Auto Show has a long tradition in the USA. This year will be the 27th time it has been held on an international stage, and more than 200 exhibitors will gather at the COBO Center on the Detroit River to present their latest offerings to a large audience. More than 18 million people have visited the show since 1989. The public days take place from 17 – 25 January. Celebrating their world premieres in Detroit are the new BMW 6 Series Convertible, Coupe and Gran Coupe, as well as the new BMW M6 Coupe, BMW M6 Convertible and BMW M6 Gran Coupe high-performance models. They will be joined at the NAIAS by the cutting-edge BMW i models and innovative services encompassing the world of electric mobility. And BMW ConnectedDrive will be showcasing its over-the-air regular automatic map updating technology.
