2015 BMW i8 Prototype

M Meets Edison
The real telling moment for the new BMW i division will be seeing how the recently tested 2014 i3 sells in its various markets, since that is the car that changes how we perceive our expectations of the brand. But this 2015 BMW i8 green supercar has all the earmarks of a slam-dunk project, we just needed to drive it and make sure for ourselves.
BMW has a spectacular test facility in southern France, called Miramas, and that's where we just had our first brief go behind the wheel of the i8. There were three cars for us there and they were dressed up in exactly the same paisley camo that we've all seen in the spy photos published everywhere for the past year. The interiors, though swathed in masking to hide all the details, varied in their color.

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.

Even 'Ring taxi drivers need to respect the Green Hell

The Nürburgring Nordschleife has the reputation as one of the most difficult tracks in the world to master - deservedly so. With 14 miles of roadway and about 160 corners over a massive amount of elevation change, the amount of grip can change from turn to turn. As the driver of the famous BMW Ring Taxi learned this weekend after a shunt into the barricades, the 'Ring can bite unsuspecting pros just as easily as amateurs.
The video of the incident below shows the M5 oversteering right into the wall as a phalanx of Porsche models arrive behind it. According to Bridge to Gantry, a website that specializes in news about the 'Ring, the taxi's passengers were picked up by another Ring Taxi and driven off with a fantastic story to tell their friends back home. "The accident happened at low speed, there were two passengers in the car, but no one had at any injuries," said BMW spokesperson Cypselus von Frankenberg to Autoblog via email.
The crash also closed track for over an hour to clean up and to haul the stricken BMW away. When a driver making a living from driving lap after lap at the Nordschleife has a crash even as seemingly minor as this one, it just goes to show why the course has the nickname 'The Green Hell.'
