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 i8: Jaw-dropping style and green performance, but why?

Why is there a BMW i8? Given the relative simplicity, affordability, practicality and energy efficiency of BMW's i3 sedan – available as a $42,000 all-electric or $46,000 extended-range EV – why design, engineer and build the much more complex and expensive ($137,450) but much less practical, exotic plug-in hybrid i8 2+2 sports car? Are i8 sales really worth BMW's huge investment of engineering effort and dollars? In 2015, BMW sold 2,265 i8s in the US, or about 189 a month. That compares to 11,024 (919 a month) for BMW's own i3, an estimated 27,840 (2,320 a month) for Tesla's battery-only EV Model S sedan and 1,024 (85 a month) for Cadillac's handsome, more practical and less expensive (but ridiculously overpriced and dismal-selling) ELR extended-range-EV luxury coupe. Are such sales really worth BMW's huge investment of engineering effort and dollars? The i8's lightweight Carbon Fiber Reinforced Plastic (CFRP) "Life Module" passenger cell rides on an aluminum "Drive Module" chassis that houses its complex propulsion system – a 228-horsepower, 1.5-liter turbocharged gas 3-cylinder (half of BMW's 3.0-liter twin-turbo straight six) driving its rear wheels through a six-speed automatic and a 129-hp electric motor twisting its front wheels through a "two-stage" automatic – and a 5-kWh lithium-ion battery. Its drag coefficient (Cd) is an aero-slick 0.26, and BMW says it can run on battery energy alone for up to 22 miles. Its total system output is a healthy 337 horses, and its EPA economy is 76 miles per gallon equivalent in gas-electric mode, but just 28 mpg when it's gas-only. A Driver Experience Control and an eDrive button offer EV and Comfort modes, plus Eco Pro (12 percent more range) and Eco Pro+ (12 more). So what is this gorgeous plug-in hybrid sports car like to drive and live with? I missed its press launch so have been hoping for some quality time with one ever since. Production has been limited, and US press cars are few, but BMW said I would eventually get my chance. It finally happened. If the unlovely i3 is a green technology revelation, this supermodel-sexy i8 is a green styling and performance revolution. If the i3 is the practical soccer mom of battery BMWs, the i8 might be the ultimate Teutonic trophy wife. But really, why do it? For starters, just look at it. Some might see a new, high-tech take on the Giugiaro-designed BMW M1 mid-engine sports car. Just 453 of those were built from 1979 to 1981.

Hamann M6 Gran Coupe is all flared and shiny

Oh, Hamann. After rolling out the ridiculously pink Mystère at this year's Geneva Motor Show, the tuning company has worked its mirror-finishing magic on the BMW M6 Gran Coupe, debuting this, the aptly named "Mirror" at the Frankfurt Motor Show. It sure is shiny, and a full 40 millimeters wider than the standard M6 GC.
Hamann says that the, um, "tailor-made suit" exterior treatment is made up of a new front bumper spoiler with large air intakes, side skirts, a new rear spoiler, and wing extensions out back. And the end result is... well, let's just call it noticeable. The special BMW rides on unique 21-inch wheels and sits a full 25 millimeters closer to the ground, as well.
As far as we can tell, Hamann hasn't upgraded the M6's 4.4-liter twin-turbo V8 at all, though there's a new sport exhaust system that "depending on the application area, either noisily announce its presence or purr sportily." Sounds like it's as loud as its newfound appearance.
