BMW M3 and M4 will rock 430 hp from twin-turbo six with standard manual [w/video]

We're not sure which spec we're most intrigued by for the new BMW M3 and M4: the twin-turbo six-cylinder with 430 horsepower and "far beyond" 369 pound-feet of torque, the 3,300-pound curb weight or the standard six-speed manual transmission with automatic throttle blipping on downshifts. That engine is fitted with both Valvetronic and Double-Vanos, twin-wire arc-spray coating in the cylinders instead of liners to save weight, a track-ready cooling system with additional radiators, a forged crankshaft, dry-sump lubrication and a magnesium oil sump. BMW says its "high revving concept" has a redline beyond 7,500 rpm.
In the M4, it will be pulling a coupe with "a weight of just under 1,500 kilograms," which is 3,300 pounds to you and me. That number is said to include no driver and 90 percent fuel, but we're still waiting on the exact number and specs. BMW says it's "around 80 kilograms lighter than a comparably equipped predecessor model," putting the power-to-weight ratio at something like 7.68 pounds per horsepower at the same time as it helps reduce fuel consumption by 25 percent. The use of carbon fiber reinforced plastics (CFRP) for the roof, drive shaft (with no center bearing), trunk and front strut brace, and forged aluminum for suspension components, have aided in the weight loss. This time around, the sedan - the M3 - will also get a CFRP roof.
The default option will be a six-speed manual.

Hamann BMW M6 Mirror can now cash the checks its body writes

Anyone remember the Hamann Mirror? Need a refresher? The Mirror is German tuning company Hamann's idea of a BMW M6. It was shown at the 2013 Frankfurt Motor Show as an M6 Gran Coupe, sporting a ridiculous paint job and some meaty, multi-spoke 21-inch wheels.
Consider this car the Mirror Mark 2. Based on the M6 Coupe, Hamann has applied a similar visual theme, using the same 21-inch wheels from 2013. Whereas the Gran Coupe rode around with a stock powertrain, though, there's been no such restraint with the two-door Mirror. A fine 620 horsepower is available from the 4.4-liter, biturbocharged V8, an increase of 60 horsepower. Torque is up as well, from 501 pound-feet to a whopping 560, meaning this M6 has speed to match its looks. Hamann claims the Mirror's newfound grunt allows it to hit 62 miles per hour faster than the standard M6 (we'd certainly hope so), although it won't mention a specific number.
The suspension, meanwhile, has been dropped 1.37 inches, or about a third of an inch lower than the Frankfurt Mirror. That drop is complemented by the Mirror's bodywork, including the exposed, carbon fiber hood and the flared fenders, which can now accommodate the enormous 305/25 rear rubber. Hamann has also paid some attention to the front and rear aerodynamics.

2015 BMW M3 and M4 priced at $62,000 and $64,200

When the BMW M3 and M4 debuted on Monday at the 2014 Detroit Auto Show, it was to much fanfare and excitement. At that time, though, we were missing a big piece of the M3/M4 puzzle - the price.
According to a report from our roundel-obsessed friends at Bimmerfest, the four-door M3 will star at $62,000, while the M4 Coupe is priced at $64,200. Those prices do not include a $925 destination charge. That's a pretty significant jump over the $56,275 starting price of the old M3 Sedan and $59,275 starting price of the last M3 Coupe, although we'd argue that these cars should easily outpace their V8 counterparts in terms of overall performance. In other news, a six-speed manual will come standard, while the seven-speed M DCT will be an optional extra.
Bimmerfest also came up with a timeline for the M3 and M4's arrival. We should expect the official announcement of pricing, along with the full order guides, released near the end of this month or in early February. Production will kick off in March, while customers will be able to begin placing orders in late April. We'll get our first crack at both cars in June, with deliveries beginning later that month.
