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.

Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.

Recharge Wrap-up: BMW X5 PHEV debuting in Shanghai, Proterra sets up shop in CA

South Carolina-based Proterra has received funding to build electric buses in California. The California Energy Commission has awarded the company, which is headed by former Tesla executive Ryan Popple, a $3-million grant. Proterra will use the funds for a facility in the LA suburb the City of Industry, where its largest customer, Foothill Transit, also operates. Proterra has also opened an office in San Bruno, just south of San Francisco. Read more at SFGate or at ValueWalk. Despite its "urban mobility" design, the BMW i3 has become popular outside of large cities. Rather than singular urban centers, "The strongholds in this country are parts of California, Texas and southern Florida," said BMW North America CEO Ludwig Willisch. He also says the electric car hasn't been particularly successful in the Northeast, with cities like New York perhaps not being as mindful of sustainability as California. BMW is also nearing i3 sales of 12,000 a year, which Willisch calls "a sustainable rate." Read more at Automotive News. BMW will debut its X5 xDrive40e plug-in hybrid at the Shanghai Motor Show this month. It is the first PHEV from BMW's core brand (not from its i sub-brand). It uses a turbocharged four-cylinder engine and electric motor for a total of 313 horsepower, and a combined fuel economy of about 70 miles per gallon (according to the ECE test cycle). Press days for the Shanghai Motor Show are April 20-21. Read more in the press release below. BMW at Auto Shanghai 2015.
