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.

Weekly Recap: Ferrari plans to gradually increase production by 2019

Ferrari has long been known for the exclusivity of its performance machines. It's on a different level than Porsche, BMW, and Mercedes. But as it transitions to a new era of independence from Fiat Chrysler, Ferrari is going to get a little less exclusive. It's by design, and it means a subtle, slow ramp-up of production – a move Ferrari believes will ensure its future by meeting growing demand in new markets. The strategy was detailed in SEC documents filed this month as part of the company's pending stock offering. The files reveal Ferrari will gradually increase shipments to about 9,000 units per year by 2019. This is a reversal of Ferrari's 2013 plans to cap production at 7,000 cars annually, which it hit on the nose that year. Ferrari shipments inched up to 7,255 in 2014, though that's down from 2012's record tally of 7,405. Ferrari is a vastly different operation than it was in 2013. Longtime chairman Luca di Montezemolo stepped down last fall, and FCA chief executive Sergio Marchionne has been overseeing the company since then. Its IPO has attracted high levels of attention from enthusiasts and investors. As expected, demand has reportedly outstripped the availability of the stock, which has an estimated offering price of $48 to $52 a share. Speaking of more Ferraris, the company revealed a limited-edition model this week called the F12tdf (shown above). Based on the F12 Berlinetta, the car is a salute to the Tour de France endurance auto race that Ferrari dominated in the 1950s and '60s. The V12 engine's output increases to 769 horsepower, while weight is cut by 243 pounds – allowing for a sprint to 60 mph in 2.9 seconds. Dramatic carbon-fiber elements and a radical redesign of the body panels give the F12 a more dramatic look. It will be limited to 799 units over the life of the car. If this is how Ferrari is increasing production, we're more than okay with the company's new strategy.

Weekly Recap: Toyota wants cars to be your 'close friends' around 2020

Toyota confirmed plans this week to launch autonomous technology in its production cars around 2020. The automaker's version is called Highway Teammate, and it's one element of a broader mobility strategy that includes vehicles communicating with each other and the grid. "Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out," the company said in a statement. That sounds utopian, and perhaps a bit cheesy, but it's an acknowledgment that autonomous driving requires more than technology developed in a vacuum. Toyota is looking at its research in a broader context, and dubs its overall strategy the Mobility Teammate Concept. Highway Teammate is the first step. Its test vehicle is a modified Lexus GS, which uses road-mapping data and external sensors to merge or exit highways, change lanes, and maintain safe distances during driving. It's operated on the Shuto Expressway in Tokyo. Toyota has been working on autonomous tech since the 1990s, with the goal of providing mobility for older people and the disabled, as well as lowering the frequency of traffic accidents. Toyota's push comes as an early adopter, Nissan, is hedging on its own deadline to implement the autonomous tech by 2020 due to a lack of firm laws governing self-driving cars around the world. Conversely, Volvo took the landmark step of being the first automaker to accept liability for when its cars will operate in autonomous mode, and urged the US government to set federal guidelines to regulate the technology. OTHER NEWS & NOTES 2016 BMW M4 GTS: Your water-injected, turbo-boosted demon BMW is unleashing its most powerful M4 ever, a 493-horsepower special edition that's road legal yet bred for the track. The company is making 700 copies for sale around the world, and 300 of them will come to the United States. The twin-turbocharged 3.0-liter six-cylinder revs to 7,600 rpm and uses a water-injection technology to cool the intake air and lower the compression temperature. BMW says this allows it to wring more power out of the inline six. The car also uses carbon-fiber reinforced plastic for the roof, hood, engine compartment strut brace, drive shaft, and rear spoiler to reduce weight. The M4 features BMW's organic light-emitting diode taillights, which are said to be an industry first.
