BMW plugs in new X5 xDrive40e PHEV crossover

BMW broke with its own convention when it rolled out the original X5 back in 1999, and did it again when it launched the i3 and i8 plug-in hybrids in 2013. Now it's bringing the two together with the reveal of the new X5 xDrive40e. Based on the third-generation F15 model and previewed by the X5 eDrive concept at the 2013 Frankfurt Motor Show, the X5 xDrive40e is the first PHEV from the core BMW brand. Its hybrid powertrain pairs a 2.0-liter turbo four (itself good for 245 horsepower and 258 pound-feet of torque) to an electric motor integrated into the eight-speed automatic transmission (contributing another 113 hp and 184 lb-ft) for a total combined output of 313 hp and 332 lb-ft. That makes it more powerful by both counts than the six-cylinder X5 xDrive35i (though considerably less so than the V8-powered xDrive50i), giving it a quoted 0-62 time of 6.8 seconds and an electronically limited top speed of 130 mph. But it can travel up to 19 miles on electric power alone, at which top speed is limited to 75 mph. BMW has mounted the 9-kWh lithium-ion battery pack underneath the luggage floor, limiting cargo capacity to between 17.65 and 60.7 cubic feet, depending on how you set up the rear seats. An adaptive suspension keeps it all on an even keel, with power transmitted to all four wheels through a permanent all-wheel-drive system. An M model it is not, but the Bavarian automaker will offer it with an M Sport package. Full details on pricing and availability have yet to be announced, but the X5 xDrive40e is set to hit European dealers in the fall. The BMW X5 xDrive40e The first plug-in hybrid production car from the BMW core brand is a Sports Activity Vehicle. Permanent all-wheel drive and the BMW EfficientDynamics eDrive technology endow the BMW X5 xDrive40e with sensational sportiness and supreme poise on the one hand and outstanding efficiency on the other. With a total system output of 230 kW/313 hp generated by a four-cylinder petrol engine with BMW TwinPower Turbo technology and a synchronous electric motor, the BMW X5 xDrive40e achieves a combined fuel consumption of 3.4 – 3.3 litres per 100 kilometres (83.1 – 85.6 mpg imp) and a combined electricity consumption of 15.4 – 15.3 kWh over the same distance. CO2 emissions come in at 78 – 77 grams per kilometre (figures according to EU test cycle for plug-in hybrid vehicles, may vary depending on the tyre format specified).

BMW i8's three-cylinder sounds like it's shaping up quite nicely

We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.
Judging by the lovely noise coming from the engine compartment of the i8 in the video, BMW's expertise in tuning high-strung, small-bore engines - remember, BMW Motorrad has quite the penchant for well-conceived motorcycle engines - has come through loud and clear. Now, it's worth mentioning that BMW's controversial Active Sound technology will be included with the i8, so the production car may not sound exactly like this version, which is running with the tech disabled. Owners won't have the ability to disable Active Sound on production i8s.
In related news, Bimmerpost reports that BMW will equip the i8 with an external Active Sound Design system to go along with its Pedestrian Protection System. That means those on the outside will likely hear piped engine recordings from the rear and a sort of "howl" from the front in order to warn pedestrians that the otherwise quiet (when running on electricity, that is) car is approaching. It will also feature technology that can stop the car before contacting a pedestrian.

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.
