Mercedes-AMG planning hybrid hypercar?

It used to be that, a few overlapping two-door models aside, Mercedes-Benz and Porsche didn't really compete with one another. That's how the two ended up collaborating on projects like the Mercedes 500 E that put it on the performance sedan map without fear of stepping on each other's toes. But Porsche has grown considerably since then, challenging its Stuttgart neighbor with four-door sedans and crossovers, as well as sports coupes and convertibles. Little wonder, then, that Mercedes has hit back at Porsche with the AMG GT, and there will be many more versions to follow in 911 style. But that may not be the final salvo the Silver Star marque launches at Zuffenhausen. According to the latest bit of speculation and deduction from our friends at Motor Trend, Mercedes-AMG may be planning a hybrid hypercar of its own to take on the Porsche 918 Spyder – not to mention the McLaren P1 and LaFerrari. Solid information is sparse at this point, but after speaking to AMG chief Tobias Moers, MT speculates that the new flagship will likely be mid-engined, with a boosted version of the company's 4.0-liter twin-turbo V8 kicking out between 650 and 700 horsepower, working with a pair of electric motors at the front to deliver tenacious through-the-road all-wheel traction and a combined output in the thousand-horsepower range. There is the possibility, though, that Mercedes could go after the latest hybrid hypercars with a flagship version of its just-launched AMG GT, packing a similar powertrain setup as the ultimate evolution of the breed. Other GT versions will likely soon include a GT3 racing model, a Black Series version and a roadster – following a similar path taken not only by the 911, but also by Benz's previous halo supercars like the SLR McLaren and SLS AMG.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

Cadillac ATS-V and Mercedes-AMG C63 S pitted Head to Head

Our favorite (and only) Autoblog-alum-turned-Motor Trend staffer is back with another Head to Head video, this time pitting the Cadillac ATS-V with the Mercedes-AMG C63 S. This performance machine shootout is ostensibly a way to figure out which of these new super sedans will earn the right to go toe-to-toe with the undisputed champion of its segment, the BMW M3. In reality, it's just a really good excuse to put three of the hottest sedans on the market on video at the same time... and there's certainly nothing wrong with that. Jonny Lieberman spends time in each of the two new challengers on the road, picking apart their powertrains, chassis and driving dynamics on the kinds of twisty roads drivers of these cars will relish. Then, he hands the keys off to Randy Pobst, who sort of acts as an unmasked version of a certain tame racing driver, except that he talks and has a personality. 0-60 and quarter-mile times are equated, braking performance is measured and scores are tallied before the two sport sedans end up at Willow Springs raceway. Interestingly enough, the car that proves (just slightly) faster at the race track isn't the car that wins the comparison. Curious? We're not going to spoil it for you. Check out the video, above. Then, for more action of these two machines, check out the videos just below.
