BMW preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.

2015 BMW i8 configurator is ready to show the future

Good news if you're one of the lucky few that can afford the new BMW i8. The high-performance hybrid's configurator has gone live on BMW USA's consumer website, meaning you can head in and customize till you drop.
If you've ever played with a BMW configurator, you'll instantly feel at home with the i8's. You have the choice of four trim packages (your author refuses to use BMW's pretentious "World" trim names), followed by wheel and exterior paint options. The interior choices are fixed to the trim level, so aside from trim, color and the choice of two wheel options, there isn't a lot to pick out on the i8.
Head on over and take a look.

Next BMW M3 sedan to be plug-in hybrid?

BMW has a lot in mind for the next-generation 3 Series and 4 Series cars, and we're hearing about it now even though they're not expected for another three or four years. The sedan is expected to be lighter, wider, with a longer wheelbase and a lower center of gravity. Rumored tech updates include the water injection system debuted in production on the BMW 1 Series, and the 4 Series convertible might go back to a fabric top. Now The Detroit Bureau reports BMW insiders have revealed that the next M3 will get a plug-in hybrid drivetrain. We've heard about plug-in variants in the mix for the G20 3 Series using a small displacement four-cylinder, but not on the M3 and possibly M4. The goal is familiar, according to the "several senior company officials:" to improve the performance while reducing the emissions footprint. Apparently, the power unit being worked on uses a "similar engine" to the 425-horsepower, 3.0-liter inline six employed at the moment, with power sent to the rear wheels. Electric assistance would come from a KERS-like unit that would also - and only - send power to the rear wheels. Torque is said to go up at least 73 pound-feet from the 406 lb-ft available currently, and all-electric range might be as much as 20 miles. Plenty of carbon fiber will help offset the weight of the lithium-ion batteries. Despite company obfuscations, we know BMW is working on a hybrid powertrain for a vehicle rumored to be called either i5 or i7, and would use one or two electric motors to drive the front wheels while the traditional ICE drives the rear wheels. This potential M3 and M4 powertrain would be an offshoot of that engineering. Automobile speculates there will be electric turbochargers and a horsepower number around 500. Related Video:
