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.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

Toyota GT86 engineers explored shooting brake and sedan variants, are they still in the cards?

According to the Toyota UK blog, engineers for the automaker were so excited developing the GT86 coupe that they investigated producing a whole family of models based on the rear-wheel drive sports car. And at least one engineer - product chief Tetsuya Tada - still hopes it can happen, even if not everyone at Toyota is onboard. Tada: "Actually we tried to do this secretly but the executives found us out. They said: 'What are you doing? Will you please focus on the coupe.'"
Those mooted variants included both a four-door sedan and a shooting brake. Why? Aside from the pure excellence of a lightweight, brilliantly handling hatchback, Toyota was keenly aware of the fact that it may need to spread the cost of development out across several models. Tada says that's part of the reason why it was so easy to create the convertible. The company knew from the outset that a softtop version was in the cards, and built the machine's structure to accommodate having the roof sliced off.
Tada also made mention of the already-announced collaboration between Toyota and BMW. The engineer said that the GT86 was particularly helpful because it demonstrated just how successful a product conceived and designed by two different companies can be. While he didn't say exactly what Toyota and BMW are up to, it's clear the two are looking into a number of possibilities. It's an interesting read with a lot of
