This BMW i8 gains Alpina V8 power thanks to tuner

German engineering firm Gabura Racing Technologies will strip out everything that makes a BMW i8 green in an effort to create a much wilder machine. Rather than a plug-in hybrid with a turbocharged three-cylinder, the company will cram in a twin-turbo V8. The firm even intends to produce a limited run of these insane conversions for customers. Gabura hasn't actually built one of these beasts yet, but it provided several glimpses of how it would work at the 2015 Professional MotorSport World Expo in Cologne, Germany. The company stuffs the engine under the front end in what looks like a quite snug fit. In several of the photos, the top of the valve covers even appears to be above the base of the windshield. According to BBC Autos, this mill is the S63 4.4-liter turbocharged V8 from the M5 and M6. Additional tuning with some help from Alpina allegedly pushes output to around 760 horsepower – more than double the i8's stock figure. One of Gabura's own six-speed sequential gearboxes reportedly transfers the power to the wheels. Gabura recently posted on Facebook that the engineers are now ready for the first conversion. They promised to "completely rebuild it inside-out, fueled with racing technology." We're very curious to see how an i8 looks and sounds after such a significant transformation.

2015 BMW M4 Coupe ditches some doors, gains some grunt

If you saw our earlier post about the hot new BMW M3 Sedan and were about to call blasphemy for no coupe version, just settle down, silly. Remember: BMW now badges its two-door 3 Series models with the number four, and thus, meet the 2015 M4 Coupe. Looks hot, right?
So yeah, it's pretty much just the M3 with two less doors, but that doesn't make it any less important - or potent. Power comes from a turbocharged, 3.0-liter inline six-cylinder engine, sending 425 horsepower and 406 pound-feet of torque to the rear wheels via either a six-speed manual or seven-speed dual-clutch transmission. You know, the usual.
Not only is the M4 more powerful than the M3 Coupe it replaces, it's a good deal lighter, too. BMW has managed to cut 176 pounds of weight out of the M4, and that means, with the increased output numbers, that the M4 will scoot to 60 miles per hour in 3.9 seconds with the DCT or 4.1 seconds with the do-it-yourself tranny. Either way, that's not what we'd call slow.

BMW 7 Series iPerformance hybrid priced at $90,095

We've known that a new flagship plug-in hybrid from BMW was coming, but the German automaker hadn't revealed any details or exactly when it would be coming. Now we know both. Today BMW released detailed information on the electrified 7 Series. The new plug-in hybrids will be available in both short- and long-wheelbase variants, with xDrive all-wheel-drive available on the long-wheelbase model. The new model will carry the 740e (or 740Le for the stretched version) iPerformance moniker. BMW also confirmed to Autoblog that the models will be available in August starting at $90,095. Drivers concerned about letting everyone know they have the most high-tech and environmentally friendly 7 Series will be happy to know that BMW has visually distinguished the hybrid. The car will carry eDrive and i badges as well as exclusive blue grille bars and hub covers. And for potential owners wishing to make a personal statement, all the other styling kits available on the normal 7 Series are also available on the hybrid. Speaking of the exterior, know that the laser headlights available in Europe will not make the trip here. Mechanically, the big Bimmer is propelled by a 2.0-liter inline four coupled to an electric motor to make a combined 326 horsepower and 369 lb-ft of torque. Power is transferred through an 8-speed automatic to either the rear wheels or all four. The electric motor, depending on configuration, can provide between 25 and 30 miles of driving on a full charge. That full charge also comes in under four hours using the standard wall charger, and under three when using the BMW i Wallbox accessory charger. When performance trumps frugality, the quickest 740Le xDrive iPerformance can hit 62 miles per hour in a claimed 5.3 seconds while it's two-wheel-drive counterparts are only 1 to 2 tenths slower. Drivers will also have a remarkable amount of control in how the drivetrain doles out power. An eDrive button will allow the driver to choose between Auto and Max settings. The former is the default setting that attempts to maximize range, but will engage the gasoline engine at 50 mph or under heavy throttle usage. The latter shifts to electric-only mode and can remain a pure EV up to 87 mph. It will still engage the combustion engine if the driver floors the throttle. Other features that control power usage are the new Adaptive driving mode and Battery Control function.
