BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

BMW i3 REx rated at 117 MPGe, 39 mpg with 72-mile EV range

The numbers haven't made their digital way to the EPA's website yet, but we can now confirm that the BMW i3 with range extender will be officially rated at a combined 117 MPGe with 39 mpg once the battery runs out. That puts the amazing little city car just ahead of the pure-electric Fiat 500e (116 MPGE, combined) and behind the Honda Fit EV (118) and the Chevy Spark EV (119). In the plug-in hybrid category, it's at the top of the class, beating out the Honda Accord PHEV, which is rated at 115 MPGe but is also a much bigger vehicle. The i3 REx also has an official all-electric range of 72 miles and can go another 78 on gas (for a total of 150). When it's not carrying around the extra fuel tank and engine, the all-electric i3 gets 124 MPGe (combined), which is the currently the highest in the US. The i3 EV also has an all-electric range of 81 miles. BMW expects to deliver the first i3 REx in the US this week and delivered the first all-electric version earlier this month. There was a bit of a hold-up on the range-extender version thanks to a delay with getting these EPA numbers. Now that all the bureaucratic boxes have been checked, it's off to customer driveways they go.

2015 BMW X4 is a budget X6

We won't argue that crossovers are hugely successful vehicles, with automakers working to provide functional CUVs in a wide range of sizes. But over at BMW, things are just getting out of hand, as evidenced by this new X4 "Sports Activity Coupe" that debuts here at the 2014 New York Auto Show.
BMW is seeing fit to offer vehicles in even the most niche of niches, and the X4 is no exception. Want proof? Have a look at the X4, and the compare it to the X3, the 3 Series Gran Turismo, the 3 Series Sport Wagon, and the 4 Series Gran Coupe. Aside from marginal differences in things like ground clearance and the exact slope of the hatchback, what, exactly, is the difference?
Like the other models we just mentioned, the X4 is powered by either a 2.0-liter turbo-four with 240 horsepower or a more powerful, 3.0-liter turbo-six with 300 horsepower, and unsurprisingly, power is sent to the ground exclusively via the company's xDrive all-wheel-drive system. An eight-speed automatic transmission is the sole gearbox available with either engine. All sounds very familiar, right?
