2015 BMW i8 [w/video]

The most important thing to keep in mind while driving BMW's all-new i8 is that it's not a product of the company's vaunted M division.
Sleek sports-coupe design, carbon-fiber construction and blistering acceleration may cause automotive enthusiasts to drool, but the i8 has not been conceptualized, engineered or assembled to be another one of BMW's world-class track stars. Instead, the i8 has been hatched as a progressive sports car from the Bavarian outfit's new i division, which "represents visionary electric vehicles and mobility services, inspiring design and a new understanding of premium that is strongly defined by sustainability." Think of it as thrilling, but with an engaging environmental twist.
It's nearly impossible to walk up to the i8 with stopping twenty feet short and taking in its styling. There's no other production car as visually fascinating - this BMW is showroom-ready sculpture that captures all of the essence of the Vision Efficient Dynamics Concept that wowed crowds at the 2009 Frankfurt Motor Show. The wind sees it as a 0.26 drag coefficient, but humans will study its beautifully crafted carbon fiber and glass panels and realize they're in the presence of the future.

2013 Dinan S3 BMW 550i

Steve Dinan has been enhancing BMW models since 1979. But don't throw his company into the ring with the dozen or so other tuners who tweak, tinker and piggyback upgrades on the famed German marque. Dinan is a tuner, but it's also an engineering firm that writes its own software, builds its own parts and then backs everything it does with a factory-grade warranty. That sort of fastidiousness comes at a price, but most of its customers - including the powerhouse of BMW Motorsport - rely on Dinan to help them come out on top.
In stock form, BMW's 550i is a formidable four-door with a twin-turbocharged 4.4-liter V8 rated at 400 horsepower and 450 pound-feet of torque. While those figures allow it to run with quick company (0-60 in 5.0 seconds, according to the automaker), Dinan puts the sedan's kettle on full boil with its S3 package. Starting with the engine, the performance engineering firm bolts on larger turbochargers, air-to-water intercoolers, a trick strut tower brace cold air intake, a quad-pipe free flow exhaust and its own engine management software. Pump in some premium fuel, and the result is 542 horsepower and 587 pound-feet of torque. Power is sent through the stock eight-speed automatic to a limited slip rear differential (Dinan will upgrade xDrive all-wheel drive models, too).
The Dinan S3 also features and extensive suspension upgrade that includes new front camber arms and low compliance rear control arms (engineered to reduce understeer and improve turn-in). The stock dampers are retained, but new bump stops are installed along with new springs. Overall, the car rides about a half-inch lower than stock to improve roll rate. To reduce unsprung weight, forged 20-inch HRE Performance wheels are fitted at all four corners (wearing Michelin Pilot Super Sport tires - 275/35ZR20 up front and 295/35ZR20 in the rear). Lastly, the company remaps the factory Electronic Damper Control (EDC) software with its own Dinan Shockware to work in conjunction with the new enhancements.

BMW planning plug-in hybrid versions of core models

To the casual observer, there's a sort of schism in the world of fuel sipping. The Japanese, Koreans and Americans have embraced electrification by way of hybrid powertrains, while our German friends lean towards diesel technology. BMW is actively pushing to change that impression, as it's announced that it will take a break from niche-busting MPVs and lifted, four-door coupes to produce plug-in hybrid versions of some of its "core-brand" models. This charge will be led by a 3 Series eDrive, whose innards are shown above, with BMW fitting a version of its turbocharged four-cylinder and an electric motor to its popular sedan. This, it should be noted, is quite a departure from the ActiveHybrid 3, which relies on a thirstier 3.0-liter, turbocharged six-cylinder. More specific details, such as the total system output, the electric range of the plug-in system or the amount of time it will take to charge, aren't yet available. BMW has, however, said the eDrive 3's systems are "directly based" on those used in the i3 and i8, and that includes larger components, like the lithium-ion battery and electric motor. "All BMW Group models benefit from BMW i. The fundamental technology involved in battery cells, electric motors and the power electronics will be used in our upcoming plug-in hybrid models," said BMW board member Herbert Diess. "When it comes to the electrification of the drivetrain, we are deliberately developing a wide-ranging expertise in order to offer our customers worldwide the ideal solution." BMW will unveil a prototype of the 3 Series eDrive in Miramas, France, although it's not clear when either it, or the X5 eDrive the company mentioned in its attached press release, will arrive to market. New generation of plug-in hybrid models Munich/Miramas. The BMW Group is preparing to follow up its innovative and revolutionary BMW i models with plug-in hybrid versions of the core-brand models. In Miramas, France, it will present a BMW 3 Series plug-in hybrid prototype and a new generation of hybrid vehicle concepts incorporating technology already used in BMW i models. Long term, the BMW Group is planning to offer plug-in hybrid versions of all its core-brand models. Herbert Diess, Member of the Board of Management BMW AG, Development, said: "All BMW Group models benefit from BMW i. The fundamental technology involved in battery cells, electric motors and the power electronics will be used in our upcoming plug-in hybrid models.
