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 i3 with range extender won't get all the EV tax benefits in NJ

Everyone loves that new-car smell, but not everyone loves that new-car tax. And whoever in New Jersey thought the extended-range version of the BMW i3 plug-in would be exempt from said tax was sorely mistaken, Green Car Reports says. To paraphrase the Garden State's favorite son, Bruce Springsteen, the first kick those drivers will take is when they hit the ground. BMW said last year that the BMW REx would qualify for new-car tax exemptions in New Jersey and in Washington State. The car's all-electric range was recently estimated at 72 miles and it has another 87 miles of gas-powered range-extended capability. Unfortunately, the range extender not only tacks on $3,850 to the car's sticker price but adds on almost that much again because New Jersey's seven-percent sales tax applies to all cars with any sort of gas-powered engine. BMW didn't respond to a request for comment about the New Jersey situation from AutoblogGreen. In other New Jersey electric vehicle news, the Consumer Affairs Committee of the New Jersey State Assembly will discuss the legality of Tesla selling directly to consumbers tomorrow. The extended-range i3 is involved in a different issue on the other side of the country. BMW said earlier this year that the REx would qualify for California's white zero-emission vehicle stickers that allow for solo access to high-occupancy vehicle (HOV) lanes. These unlimited white stickers can go on any EV, but the REx version only qualifies for the green stickers, which are designated for plug-in hybrids and extended-range plug-ins and the state has run out of those.

Cadillac ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.
