BMW i8 and M1 reunited in mid-engined Bavarian retrospective

The BMW i8 may be the cutting edge today – it did, after all, just win our Technology of the Year award – but as rare an event as it is, it's not the first time that BMW has put out an extreme mid-engined supercar. The last time was in the late 1970s with the M1, a Giugiaro-designed, (partially) Lamborghini-developed piece of exotic machinery. The better part of four decades later, Auto Express has brought together an original M1 with its spiritual (if much more advanced) successor for the video comparison that was bound to happen. The question we can't help but ponder, initial sales success aside, is whether the i8 will mature into a classic in the same way the M1 has.

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 Shadow Sport limited edition opens a moon roof on US

Here's a bit of news for a quarter-million dollars. BMW is bringing a special edition i3 called Shadow Sport to the US for the 2016 model year. That tag refers to the special-edition Bimmers that come equipped with a moon roof, which before this was unavailable in the US. But only 50 lucky folks will get them. The Shadow Sport edition comes with a few other goodies, too, including "fluid" black paint, 19-inch alloy wheels, custom-trim interior and sport-tuned suspension, though there are no changes in the electric motor or performance. That means the same single-charge range of 81 miles, the same 0-60 miles per hour acceleration time of seven seconds flat and the same top speed of 93 miles per hour. If you experience a little slower speed and a little shorter single-charge range because you're spending too much time looking out of the moon roof, that's on you. The catch is that the model won't be available for the i3 vehicles with the gas-powered range extender, i.e. the i3 REx. The Shadow Sport will also have a price of $47,400, or $5,000 more than the base model i3. BMW's Dave Buchko told AutoblogGreen that all 50 Shadow Sports have been sold, with the first 40 selling out in the first hour or so of availability. The Shadow Sport is on display at the Los Angeles Auto Show this week. Through the first 10 months of the year, BMW sold 8,879 i3 vehicles, which was double year-earlier figures. Last month alone, though, things weren't as rosy, as October i3 sales declined 15 percent from a year earlier to 986 units. There's more information at the bottom of BMW's LA Show press release, below.
