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.

2014 BMW 740Ld xDrive does diesel in a big way

Slowly but surely, BMW is expanding its lineup of diesel-powered models here in the United States. In addition to the 328d sedan and wagon, 535d sedan and X5 xDrive35d crossover, we now have this, the BMW 740Ld xDrive (not to mention the refreshed 2015 X3 xDrive28d that also makes its debut here in Chicago). As its name - and the photos above - suggest, this means BMW is offering diesel power in its flagship, long-wheelbase 7 Series sedan, set to directly compete with the likes of the excellent Audi A8 TDI.
Under the hood is BMW's familiar 3.0-liter turbocharged diesel inline-six, delivering 255 horsepower and 413 pound-feet of torque, all of which is sent to the road via the company's xDrive all-wheel-drive system and ZF eight-speed automatic transmission. That torque thrust is available straight away from 1,500 rpm, and BMW says the 740Ld xDrive will sprint to 60 miles per hour in a very respectable 6.1 seconds. Official fuel economy estimates haven't been released yet, but we expect the car to net highway fuel economy ratings in the mid-30 range.
The 740Ld xDrive arrives in BMW showrooms this spring, priced from $82,500, not including $925 for destination. We're pretty stoked to drive it. But in the meantime, have a look at fresh images of the big sedan live from the Chicago Auto Show, above.

BMW i3 gets official worldwide

Even though we recently drove a near-production version of the BMW i3, the car still wore light exterior and interior camouflage. Today, BMW took off that little bit of camo and made a big announcement: The i3 will go on sale in the US for $41,350 in the second quarter of 2014. That does not include any state or federal incentives that could lower the price or the $925 destination fee. The i3 will debut with three trim levels, which BMW is referring to as Worlds: Mega (standard in the US), Giga and Tera.
The BMW i3 is chock-full of new technology afforded by its design as an EV from the start of development, which has resulted in a vehicle layout unique to the i3. BMW has named it LifeDrive architecture, and it features the Life Module and the Drive Module. The Life Module is the i3's pillar-less passenger cell, which is the first mass-produced monocoque made of carbon fiber reinforced plastic (CFRP). The tougher-than-steel material is also 30-percent lighter than aluminum, which contributes to the i3's relatively light weight of 2,700 pounds (preliminary US figure) and, in turn, increases its energy efficiency. Expect more of this technology to find its way into future BMWs.
The Drive Module, a 100-percent aluminum chassis mounted under the Life Module, houses everything that makes the i3 go. It includes the 22-kilowatt, 450-pound lithium ion battery mounted as centrally as possible, and provides power to a rear-mounted electric motor that turns the rear wheels. With 170 horsepower and 184 pound-feet of torque from zero rpm, the single-gear i3 can accelerate from 0-30 miles per hour in 3.5 seconds and 0-60 mph in about 7.0 seconds, but it has a top speed of only 93 mph. BMW says the i3 has a real-world EV range of 80-100 miles, and the standard charger can fill the battery in three hours. Opt for the SAE DC Combo Fast Charger and 30 minutes is all it takes for a full charge; 20 minutes will bump the battery to 80 percent. For customers who have range anxiety, BMW gives them the option to install a 34-hp, 650cc two-cylinder generator as a range extender for the electric drive system.
