BMW celebrates 30 years of M5 with 600-hp super sedan

It's been 30 years since BMW rolled out the first M5, and while displacement and cylinder count may have fluctuated over those past three decades, output has only increased. The first-generation E28 M5 packed a 3.5-liter inline-six with 252 horsepower and 243 lb-ft of torque. The second-gen E34 model that followed added an extra 100 cc (and later 200 more) to produce 310 hp and 266 lb-ft. The E39 followed with a 4.9-liter V8 churning out 394 hp and 369 lb-ft, replaced by the award-winning 5.0-liter V10 in the E60 with its 500 hp and 380 lb-ft before BMW rolled out the latest model with a 4.4-liter V8, its twin turbos making up for the two dropped cylinders and 600 cc of displacement to produce 560 hp and 502 lb-ft of torque. But even that's being left in the dust by the new special edition you see here.
The 30th Anniversary Edition BMW M5 packs that same 4.4-liter twin-turbo V8, but cranks the output up to a nice, round 600 horsepower and a solid 516 lb-ft of torque to go with it. That makes it more powerful, not only than any M5 that's come before it, but also any of its rivals. The Jaguar XFR-S and Audi RS6 Avant (the latter only available as a wagon and not in North America) both lag behind this ultimate of Ultimate Driving Machines; only the Mercedes-Benz E63 AMG trumps it on torque (but not on power), with 531 lb-ft in stock form and 590 in the S-Model.
As a result, the 0-60 time drops from a quoted 4.2 seconds in the stock M5 to a scant 3.7 in the 30th Anniversary edition (just one tick behind that twistier E63 S). The special M5 also comes with the Competition Package as standard, as well as a dedicated control module for the Active M Differential, a special Frozen Dark Silver matte finish, 20-inch alloys and black chrome badges. Special badges abound inside as well, where you'll also find black leather and Alcantara upholstery and aluminum trim. There'll even be a dedicated one-day course offered to owners at The Thermal Club in Palm Springs, CA, to further sweeten the deal.

BMW i8 with 500+ horsepower in the cards?

While BMW makes plenty of machinery to keep enthusiasts interested, its most enticing models are often based on more ordinary ones. That's what made the arrival of the i8 so captivating, emerging as the first stand-alone BMW sports coupe since the M1. But if its dual purpose - trying its best to both embrace the earth and traverse it rapidly - somehow left you disappointed, the next development could prove to fix that.
According to Automobile, BMW is working on a more potent i8S model. The hardcore version of the hybrid sports car would offer more power and a stiffened chassis to make it that much more aggressive. The Bavarian automaker is reportedly still evaluating two potential powertrain options: The first would pair a 2.0-liter twin-turbo four-cylinder good for 320 horsepower to an electric motor with another 204 hp. The second would use a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Both would be mated to a nine-speed dual-clutch transmission and an integrated starter motor packing an extra 27 hp.
Either way, we'd be looking at a combined output well in excess of 500 horsepower - far more than the existing i8's 228-hp turbo three and 129-hp electric motor - dropping the 0-62 time down from 4.1 seconds to an estimated 3.5. Couple that to a more advanced carbon chassis, wider tires and other goodies, and the i8 would be transformed into a far more capable performance machine than it already is.

2016 BMW M4 GTS: More power, less weight, ready for the track

BMW calls its new M4 GTS the "most agile, radical, and powerful M4 ever." It's got 493 horsepower, a slick new water injection system, a three-way adjustable coilover suspension, and a weight reduction of roughly 200 pounds compared to a stock M4. Only 700 will be built, with 300 allocated for the United States. And did we mention it looks absolutely killer? Let's talk about that water injection system for a moment, because it's the first time this technology is being used on [an intercooled - Ed.] production road car. Basically, water absorbs heat from surrounding air, so a fine mist is sprayed into the intake manifold where it evaporates, lowering the temperature of the intake air. BMW says this reduces final compression temperature, allowing the turbochargers to operate with increased boost pressure and better spark timing. The end result is increased output – 493 horsepower and 442 pound-feet of torque from the same twin-turbo, 3.0-liter straight-six as the standard M4. That's an increase of 68 hp and 36 lb-ft. But the GTS isn't just about increased power. In fact, the bigger story is its weight reduction. BMW incorporated the use of aluminum and carbon fiber throughout the M4's construction, and DIN curb weight is listed as 3,329 pounds. It's unclear if that's the exact US measurement, and BMW couldn't comment on that as of this writing, but compared to our 3,530-pound stock M4, that represents some 200 fewer pounds of heft. Carbon fiber reinforced plastic (CFRP) is used in the hood, making that part some 25 percent lighter than the stock piece. CFRP is also used for the driveshaft, making it 40-percent lighter than the standard setup. Even inside the car, the new center console is 30-percent lighter than what you'd find in a normal M4. The rear seats are gone, and we're sorry to say that the cool racing buckets pictured here won't be available in the US. Making this thing super capable at the track is a three-way M coilover suspension, combined with upgraded carbon ceramic brakes, set behind staggered wheels and tires. Up front, the GTS rides on 19-inch rollers wrapped in 265/35-series Michelin Pilot Sport Cup 2 tires, and out back, 20-inch wheels are fitted inside 285/30-series rubber. The only transmission available is the seven-speed, M DCT dual-clutch unit, and when all is said in done, BMW says the M4 GTS will run the infamous Nurburgring Nordschleife in 7 minutes and 28 seconds. Another cool feature: organic LED technology.
