BMW M4 vs. Lexus RC F in Head 2 Head sports coupe showdown

It's the showdown everyone's been looking forward to, the East versus West grudge match of the year. We're talking, of course, about the BMW M4 versus the Lexus RC F.
Although BMW uses a twin-turbo straight-six and the Lexus uses a free-breathing V8, the two are pretty closely matched on paper: a luxury coupe with over 400 horsepower channeled to the rear wheels.
The BMW has been doing these cars for longer, and the M4 boasts a higher power-to-weight ratio. But then the RC F has more power - and without forced induction to break up the rev range. So which is the better luxury muscle coupe? Watch the latest episode of Motor Trend Head 2 Head to find out.

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.

2015 BMW i8 offers you a fast ride to the future for $135,700* [w/video]

BMW's long-form teasing and rollout of its incredibly cool i8 has put us in a unique position to report from its world debut here in Frankfurt. Typically, an auto show debut marks just the start of the information dump about a new vehicle. The i8, however, is a car that we've already driven and reviewed, so perhaps the biggest news from the show floor is the official price of the thing, as well as getting to see it live and in person, of course.
Arriving in US showrooms in the spring of 2014, the i8 performance plug-in hybrid will carry a price tag of $135,700 (*not including $925 for destination and handling charges). That kind of cash puts the i8 near the very top of the BMW range (slotting just under the top-trim 7-Series models), and will buy a massive amount of new technology.
The four-seat i8 has the look of a true supercar, and its new-tech drivetrain will offer up the performance of a stirring sports car, at least. A TwinPower Turbo, three-cylinder, 1.5-liter engine will make 231 horsepower and 236 pound-feet of torque that's gets sent to the rear wheels, while a 96-kilowatt electric motor doles out 131 hp and 184 lb-ft of maximum torque to the fronts. Total system output of 362 hp and 420 lb-ft allows the i8 to sprint to 62 miles per hour in 4.4 seconds with all-wheels-driven handling, and it still returns an astonishing 94 miles per gallon US.
