The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed

The BMW specialists at Alpina know how to exploit a niche when they see one. With the BMW M4 still not technically official, it saw the need for a higher performance four-seat convertible than the 435i 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the Geneva Motor Show.
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).

2015 BMW 1 Series facelift revealed [w/video]

While we don't get the BMW 1 Series at all in the US anymore, European buyers are getting a refresh of the luxury compact hatchback for the new year. Unlike the German brand's recent work on the 6 Series, the work is actually noticeable and improves things nicely. Up front, BMW keeps the changes subtle. The lower airdam is tweaked with larger air intakes and less chrome than before. The redesign and better sealing around the reshaped, narrower headlights also help optimize airflow and – in our eyes – improve aesthetics. LED running lights are standard now, and full LED units are optional. The more striking changes come at the back, where the 1 Series now wears the Bavarian brand's latest L-shaped taillights. The lights wrap around the sides and cut into the hatch to create a much more visually interesting look. The lower apron gets some small changes as well, and it all works together to create a more cohesive look. The BMW hatchback also gets some engine tweaks to go with its updated style. A new 2.0-liter four-cylinder is offered in 150-, 190- and 224-horsepower tunes. For those who want the best fuel economy, the 116d EfficientDynamics Plus makes 116 hp from a 1.5-liter turbo diesel and features active air flaps and redesigned kidney grille bars for better aero. The top-spec M135i with its 3.0-liter turbocharged inline-six gets a six-hp boost to 326 hp, too. Updates to the eight-speed automatic give it longer gearing and predictive shifting based on the vehicle's navigation system data. All of the new models hit the market in Europe later this year, specifically in late March for the UK. Read below for BMW's full list of tweaks and changes and to see it in motion on video. The BMW 1 Series for 2015 16.01.2015 Nearly two million 1 Series models have been sold since the introduction of the first 1 Series generation ten years ago. This latest incarnation builds on the winning formula of these three- and five-door predecessors with new power units from the latest BMW engine family, additional EfficientDynamics technologies fitted as standard, and careful enhancements to the exterior and interior design. The level of standard equipment is now even higher, new options have been added and with new mobility services from BMW ConnectedDrive, there are even more ways to increase the functionality and personalisation of the new 1 Series.

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.
