2019 BMW M850i xDrive: How it compares on paper with other GT coupes

Although the hot new vehicles for the rich seem to mainly comprise SUVs and supercars, the neglected luxury GT coupe segment is starting to see some life again. The latest to add a spark to this set is the 2019 BMW M850i xDrive. It goes on sale later this year, and revives the 8 Series that's been dead since the 1990s. The first version available to Americans will be one with a twin-turbo 4.4-liter V8, with other versions likely following. Before it launches, we wanted to get a lay of the grand-touring land and see how the new BMW stacks up to the competition in performance, practicality and price. While some of these models have higher-performance or more-affordable iterations, we picked the versions that would be the closest match to this 8 Series model. They include the 2019 Lexus LC 500, 2018 Mercedes-Benz SL 550, 2018 Mercedes-Benz S 560 Coupe and the 2018 Maserati GranTurismo. We will also provide some short summaries on our experiences with these cars, but to get a full picture of each model, be sure to check out their full reviews.

Engines, transmissions and performance On paper, the BMW M850i xDrive is clearly the performer of the group. It has the most power and torque at 523 horsepower and 553 pound-feet. Coupled with all-wheel-drive and an eight-speed automatic, the car is able to overcome its relatively portly 4,478-pound curb weight to hit 60 mph in a scant 3.6 seconds. That's more than half a second quicker than the lightest car in the group, the Mercedes-Benz SL550, which weighs 4,012 pounds. The other three vehicles are in the low- to mid-4-second range to 60 mph. Though the Maserati is the slowest to 60 mph, it does boast the highest top speed of 186 mph. The M850i and SL 550 are electronically limited to 155 mph, while the Lexus is limited to 168 mph. The Mercedes S 560 has the lowest top speed at an electronically limited 130 mph.

The BMW and Mercedes resort to forced induction, whereas the Lexus and Maserati choose to stay naturally aspirated. This is likely why the Germans break 500 pound-feet of torque, while the others don't make it to 400. Also interesting is the spread of gear quantity. The Maserati has just six ratios to choose from, and the Lexus has a whopping 10.

AC Schnitzer packs 400-hp, tri-turbo diesel into 1 Series

At first blush, this might look like your run-of-the-mill BMW 1 Series, maybe with a few modifications. What you're actually looking at is a monster hot hatch with 400 horsepower and 590 lb-ft of torque. From a diesel. For this year's Essen Motor Show – Germany's equivalent to SEMA – the Bimmer specialists at AC Schnitzer prepared the ACS1 5.0d concept you see here. Its selling point (if only it were for sale) is the combination of BMW's most powerful diesel engine and its smallest model. It utilizes the 3.0-liter triple-turbocharged inline-six diesel engine from the M50d versions of the 5 Series, X5, and X6 sold in Europe. That engine is normally rated at 376 hp and 545 lb-ft, which is already a ton of muscle. But Schnitzer has bumped up the output on both counts, and slotted it into a 1 Series hatchback. The result is a 0-62 time of just 4.5 seconds, leaving the M135i and M235i in a cloud of diesel soot. Of course, Schnitzer has plenty more to showcase at Essen this year, including modifications for the 3 Series, X6 M, and Mini JCW. And you can bet all the other major European tuners will be on hand at the expo to show their wares, too. But as far as outlandish creations go, this monster diesel hot hatch is what's caught our attention. Compact and incredibly powerful The 1-series by AC Schnitzer with impressive motorsport quality At first sight, you do not expect brute force from the BMW 1-series. So the performance of the compact Bavarian after the AC Schnitzer tuning experts have equipped it with the M50d power plant and impressive performance upgrade, is even more incredible. Originally designed for the 5-series, the "Diesel M-Technik" pack propels the 1-series a long way forward. The smallest BMW series now has an impressive drive concept from AC Schnitzer. After the performance upgrade, the concept engine of the ACS1 5.0d delivers 294 kW/400 hp and 800 Nm torque for generous thrust. Equipped in this way, it takes just 4.5 seconds to sprint from 0-100 km/h. The acceleration from 80-180 km/h is even more impressive: the ACS1 5.0d takes just 7.9 second for this. The smallest of the compacts, the 114i, is already impressive thanks to a power increase by 52 hp to 154 hp. The four-cylinder petrol engine of the 116i, thanks to motorsport technology, now delivers 204 hp instead of 136 hp. The same figure is also achieved by the 118i, which previously had 170 horses under the bonnet.

BMW X4 reclaims dash of utility with Clemson student project [w/videos]

BMW seems willing to exploit every automotive niche it can find with creations like the four-door, 'crossover coupe' X4 and X6. Of course, these designs come with a compromise. That svelte fastback means that they just can't haul as much cargo as a more traditional, boxier hatchback. Fortunately, students at Clemson University's International Center for Automotive Research might have a novel solution: the engineering graduate program has turned the crossover into a unique pickup.
Dubbed Deep Orange 4 concept, this functional prototype has an enclosed cargo area with a sliding glass panel that opens up to expose a pickup bed if more room is needed. Think of it as the GMC Envoy XUV of German crossovers. This isn't just an X4 with its roof hacked off, though. The students actually started with an X3 and grafted on this top later in addition to the two barn doors for access to the bed.
To make this project even more impressive, this pickup-crossover could conceivably be produced. The graduate students conducted an in-plant analysis of BMW's manufacturing abilities and went back to the university to create a plan for a low-volume vehicle that could actually be built. "The students working on this phase of the project did an excellent job of keeping costs down while finding optimal integration opportunities," said Rich Morris, vice president of assembly at BMW Manufacturing, in the university's release.
