M-fographic breaks down the history of BMW performance machinery

Few characters carry the kind of clout among performance enthusiasts as the letter M. For 35 years now, that one letter has adorned over 300,000 BMWs, each tuned to deliver a higher degree of performance than the stock models on which they're based.
The M division has worked up nearly 100 different models over the past third of a century, which can leave even the most expert among Bimmer fanatics bewildered. Fortunately British auto loan service Carfinance247 has commissioned this handy infographic to make sense of it all, and you can check it out below to see what the letter M really stands for.

EVO takes flight in BMW's sultry i8

Electric cars and hybrids are here to stay, much to the apparent dismay of some auto enthusiasts, but that doesn't mean they have to represent the death of enjoyable driving. Granted, the initial run of hybrids in the US like the Honda Insight and Toyota Prius weren't exactly tailor-made for aggressive folks behind the wheel, but things are clearly changing. In its latest video, Evo takes a look at three examples from Europe's new crop of electrified vehicles to show that the future of fun motoring is safe and sound.
Evo editor Henry Catchpole kicks things off with one of the most bizarre EVs of the bunch, the tiny Renault Twizy. Its low power and 50-mile-per-hour top speed might make it miles away from a hot hatch, but there's still fun to be had in extracting the most from this little city car. Next up is the Audi A3 E-Tron, which isn't technically available yet. It's a step in the right direction of eventually creating an affordable, fun-to-drive hybrid hot hatch.
However, the main event is Catchpole getting some seat time in the BMW i8. The Bimmer can really fly -literally in this case - and the butterfly-door coupe offers a clear look at the prospects for electrified sports cars. It might not have the power of hybrid supercar contemporaries like the LaFerrari or Porsche 918 Spyder, but the BMW doesn't cost nearly as much, either. See? Improved efficiency doesn't have to mean boring.

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.
