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.

Why this could be the perfect time for Apple to make a car play

While the automotive and technology worlds have been pouring billions into autonomous vehicles (AVs) and preparing to bring them to market soon as shared robo-taxis, Apple has mostly sat on the sidelines. Of course, Apple is the last company to ever make its intentions known, and the super-secret tech cult giant hasn't been totally out of the AV game based on the clues that have slipped out of its Cupertino, Calif., citadel over the past few years. Related: Apple self-driving cars are real — one was just in an accident News first broke in 2015 that it had assembled an automotive development team, in part by poaching high-profile talent from car companies, to work on a top-secret self-driving vehicle project code-named Titan. (Thank you very much, Nissan.) Apple also subsequently broke cover by making inquiries into using a Northern California AV testing facility and receiving a permit to test AVs on public roads in California. But then as the AV race started to heat up in the last few years, Apple reportedly began scaling back its car activities by downsizing team Titan. More recently, Apple's car project has shown signs of life with the hiring a high-level engineer away from Waymo and luring one Tesla's top engineers and a former employee back to Apple. It also inked a deal with Volkswagen to provide a technology platform and software to convert the automaker's new T6 Transporter vans into autonomous shuttles for employees at tech company's new campus. That is a far cry from giving rides to Wal-Mart shoppers, like Waymo is doing as part of its AV testing in Phoenix. But this could be the perfect time for Apple to enter the AV market now that ride-sharing is reaching critical mass and automakers and others are planning to deploy fleets of robo-taxis. Apple could easily establish a niche as a high-end ride-sharing service – and charge a premium – given its cult-like brand loyalty and design savvy. The growth of car subscription models could also play in Apple's favor since is already has many people hooked on paying for phones in monthly installments – and eager to upgrade when a new and better model becomes available. To achieve this, some believe Apple will fulfill co-founder and CEO Steve Job's dream of building a car. And as the world's first and only $1 trillion company it's sitting on a mountain of cash that certainly gives it the means. But other tech darlings like Tesla and Google have discovered how difficult it can be to build cars at scale.

BMW X4 tunes up its crossover game in Germany

Except for the fancy wheels and the overly expressive fascias, the production version of the BMW X4 looks like it will carry over practically untouched from what we saw in the X4 Concept several months back. With the same fastback roofline as the concept, these spy shots show that the X4 is taking shape to be a baby version of the BMW X6.
Sharing the same platform as the X3, the lower and wider X4 will be positioned slightly more upmarket - as is the case with the X5 and X6. We hear that this could mean that the X4 will ditch the X3's base engine to give an even sportier feel right out of the gate, but word has it that an M version will being showing up down the road as well.
BMW has already revealed what it plans to show off at the Frankfurt Motor Show (i3, 4 Series Coupe, next-gen X5, refreshed 5 Series, X5 Concept eDrive plug-in hybrid and Concept Active Tourer Outdoor), so barring any surprised we definitely won't be seeing the X4 there. At this point, with as close to production as these images would have us believe, our best guess would be that we'll see the X4's official unveiling happen either at LA or Detroit.
