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.

Comparison test: 2019 Acura RDX vs. compact luxury SUV competitors

Truth be told, if we were to compare the all-new 2019 Acura RDX with those compact luxury crossover SUVs it would most likely be cross-shopped against, you'd be looking at a different list. Even Acura admits that Lexus and Infiniti are the most likely bogies, but with the 2019 RDX, Honda's luxury brand is attempting to attract those customers who think as much with their hearts as with their heads. And for the most part, those folks have been buying from German brands: the Audi Q5, BMW X3 and Mercedes-Benz GLC-Class. So, to show how the new RDX compares to them, Acura actually provided examples of each during the recent press drive along with a Volvo XC60. All were determined to have greater emotional appeal than the last RDX, and we would certainly agree. For, as much as the previous-generation RDX made sense on paper, it was really hard to get excited about it. And when you're paying extra for a luxury vehicle, shouldn't you get a little excited? Well, as luck would have it, Consumer Editor Jeremy Korzeniewski and I were on hand in Whistler, British Columbia, for the press launch. We didn't have an abundance of time in each RDX competitor, but in conjunction with our usual comparison chart, our impressions should provide a good first taste of how the new RDX compares. Performance and fuel economy Contributing Editor James Riswick: On paper at least, the RDX is gutsier than its comparably powered European rivals. It also weighs the same or less, which logically should mean it'll be the quickest in a straight line. During my brief drives, though, I'm not sure it really stood taller than the three Germans. It at least matches them for smoothness, which is something that can't be said about the Volvo. Fuel economy is lower than them all when you consider all but the Mercedes come standard with all-wheel drive. It's also worth noting that all the competitors are available with engine upgrades, and unless Acura's forthcoming resurrection of Type S models includes the RDX, it should stay that way. Consumer Editor Jeremy Korzeniewski: Line 'em all up in a drag race, and I have a feeling the Acura would squirt away to victory. A good bit of that, though, would be due to its 10-speed automatic transmission, which offers a huge spread of ratios and fires off extremely quick shifts. In the real world, I'd guess fuel economy will be similar across the board, so I'm willing to call that category a draw.

Jay Leno puts focus on some retro-inspired BMW bikes

Jay Leno puts eight wheels on display this week for Jay Leno's Garage from a quartet of retro-inspired BMW motorcycles. They are the creations of husband and wife team Larry and Carol Romestant, who build each one in their home garage.
Larry is a former aerospace engineer who loves BMW bikes, especially the K models. Now, he's combining his passion with a real talent for fabrication to build his own cycles with his wife. With Larry and Carol the only ones working on these projects, it takes them six to nine months to build each one. In addition to the old-school looks, the motorcycles are supposed to be a bit more user friendly than stock. For example, one of them ditches the standard five-speed gearbox in favor of a six-speed unit to be a little more comfy when cruising at high speeds.
Since there isn't enough time to take all four of them for a ride, Jay picks his favorite to test out on the open road. Scroll down to see which one he chooses.
