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.

BMW planning six-cylinder i9 hybrid to celebrate centenary?

On the prospect of a new BMW M1 based on the company's new i8 hybrid, the jury has been in and out so much that we can't even tell which way it's likely to go. However, the latest reports coming in from Germany suggest that BMW may have something else up its sleeves. Rather than make a conventional gas-powered version of the i8, Germany's Auto Motor und Sport says BMW will make a more powerful one.
Tentatively dubbed i9, the hybrid sports car is rumored to pack a six-cylinder internal-combustion engine instead of the i8's turbo three. Coupled to more potent electric motors, it would figure to produce even more than the 357 horsepower and 420 pound-feet of torque already on tap in the i8, with further weight reductions to offset the bulkier engine.
Auto Motor und Sport says the mooted model will be produced to celebrate the Bavarian automaker's 100th anniversary and eclipse the i8's performance, with a projected 0-60 run in under four seconds en-route to taking the gloves off to crunch the Autobahn in electric bliss. The new i flagship would be another member of the company's growing electrified family, joining the existing i3 hatchback, upcoming i5 minivan and possible i8 Spyder down the line.

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.
