Chris Harris and David Coulthard wring out a Mercedes Fintail at the N"urburgring

If there's one thing we've learned from the latest video from Drive, it's that the combination of Chris Harris and David Coulthard will produce some very quotable moments. Take this exchange, for example.
DC: "We are by some way the slowest."
CH: "But we're in a class of three cars, apparently."

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

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. And if you want to compare any of these cars with models you don't see here, be sure to try out our car comparison tool. 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.
