Alpina XD3 Bi-Turbo offers facelifted looks, diesel-powered 4.9-sec 0-62 sprint [w/video]

I've always thought it would be fascinating to look at the psychographic data of Alpina's customer base. While the company's high-zoot rendition of BMW 7 and 5 Series sedans makes plenty of sense, I don't quite understand the appeal of the still-expensive tunes, further down the range. Enter the European-only Alpina XD3 Bi-Turbo, which made its debut here in Geneva today. The XD3 has been around for a bit, but this year it's refreshed to coincide with the BMW X3's own nip-tuck. The result is essentially a new front and back fascia on the same, ginormous Alpina wheels that make the brand's products instantly recognizable. For anyone that covets huge diesel performance in a small SUV-shaped package, that's a good thing. The XD3 pushes a whopping 516 pound-feet of torque and 345 horsepower out of its 3.0-liter, biturbo sixer, all good for a 0-62-mile-per-hour sprint of just 4.9 seconds. Which is quick by any measure. Still, the privilege of driving the fast, high-center-of-gravity Bimmer doesn't come cheaply – Alpina would like just over 69,000 euro ($77,000 by today's rates) for each example. That kind of coin will buy a European equal performance in the form of a Porsche Macan diesel, or any number of non-SUV performance rides, too. It takes a special mind, I suppose... Related Video:

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.
