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.

Mini Vision Next 100 concept invokes an alternate universe

Sir Alec Issigonis, designer of the 1959 Mini, would probably find Mini's new Vision Next 100 concept amusing. The original Mini was largely an exercise in efficient packaging and clever engineering. That it was handsome, and became iconic, was more a product of its wild success than an intentional product of its exterior styling. While the Mini concept is undoubtedly cleverly packaged, it's almost purely a styling exercise, no matter what sort of futuristic connected/autonomous functionality Mini says it'll have. Mini doesn't seem able to move past the Mini as a caricature of itself. The heavy, floating roof, the vestigial round and friendly "headlamps", the oversized gauge pod. This seems very German, the inability to communicate essential brand attributes without using cliches. Mini is in a styling rut, trying to evolve the same basic styling language with each new generation, stretching it over larger hard points. The Vision Next 100 program would have been a great time to communicate to the public that Mini is more than just styling tropes: it's an attitude, a way of thinking, a connectedness to the driver. More than a badge or bug-eyed headlights. To its credit, the interior is massively decluttered. That's in part to the rear-engine layout, but more on that in a follow-up piece. The comparatively vast footwell and ultra-minimalist dash pair well with the giant windscreen. It feels light, airy, and authentic to the ideals of the originally Mini in terms of space efficiency, without being overly sentimental. Futurism is a thankless profession, and we can't take this concept literally as a vision of what the brand will be in 100 years. We can say this: it doesn't seem that Mini will be able to transcend the styling tropes that currently define Mini. Let's hope they find a way out of their rut.

BMW i8's three-cylinder sounds like it's shaping up quite nicely

We've run across some rather interesting news... or perhaps we should say interesting sounds. The folks from Bimmerpost have scrounged up a short video showing a preproduction BMW i8 running through a few gears in Sport mode at a quick pace, and if you were concerned that the somewhat eco-friendly nature of the upcoming German sports car would neuter its ability to stir the aural senses, fret not.
Judging by the lovely noise coming from the engine compartment of the i8 in the video, BMW's expertise in tuning high-strung, small-bore engines - remember, BMW Motorrad has quite the penchant for well-conceived motorcycle engines - has come through loud and clear. Now, it's worth mentioning that BMW's controversial Active Sound technology will be included with the i8, so the production car may not sound exactly like this version, which is running with the tech disabled. Owners won't have the ability to disable Active Sound on production i8s.
In related news, Bimmerpost reports that BMW will equip the i8 with an external Active Sound Design system to go along with its Pedestrian Protection System. That means those on the outside will likely hear piped engine recordings from the rear and a sort of "howl" from the front in order to warn pedestrians that the otherwise quiet (when running on electricity, that is) car is approaching. It will also feature technology that can stop the car before contacting a pedestrian.
