Mercedes-AMG could use electric turbos

Mercedes-Benz is joining Audi in analyzing electric turbochargers for its production cars. But while Ingolstadt will roll out its first e-turbo in its A8 luxury sedan, Stuttgart is studying the technology for use in small performance cars, like the A45, CLA45, and GLA45 AMG models. Auto Express spoke to Mercedes-AMG compact car boss Steffen Jastrow about the cutting-edge tech, which reduces turbo lag, improves fuel economy, and occupies less space under the hood than a standard turbo. "Of course we need more power for the next-generation of cars, but electrification does not mean we have to use an electric drivetrain." Jastrow said. "They have to be faster and e-turbos are an option. We use them in motorsport, but the technology has to be payable for the customer." As AE tells it, bringing the price of e-turbos down from the A8's luxury car level to the relatively affordable sums demanded by compact AMG models will still take some time. So don't count on seeing a Mercedes with an electric turbocharger until the new A-Class arrives in 2017, at the earliest. Related Video:

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.

Geely wants to be a tech-sharing 'friend' of Daimler in $9B bet

Chinese carmaker Geely has built up an almost 10-percent stake in Daimler in a $9 billion bet by its chairman that he can access the Mercedes-Benz owner's technology in the growing battle for the future of automotives. The purchase by Li Shufu, Geely's founder and main owner, means China's largest privately-owned automaker is now the biggest shareholder in Germany's Daimler. Geely said on Saturday there were no plans "for the time being" to raise the stake further. Instead, it will seek to forge an alliance with Daimler, which is developing electric and self-driving vehicles, to respond to the challenge from new competitors such as Tesla, Google and Uber. "No current car industry player is likely to win this battle against the invaders from outside without friends. To achieve and assert technological leadership, one has to adapt a new way of thinking in terms of sharing and combining strength. My investment in Daimler reflects this vision," Li said. "Daimler is pleased to announce that with Li Shufu it could win another long-term orientated shareholder, which is convinced by Daimler's innovation strength, strategy and future potential," the German company said in a statement. Geely officials plan to travel to Stuttgart to meet Daimler executives early next week and also hope to meet top German government officials in Berlin, two sources familiar with the matter told Reuters. The Chinese firm plans to use the meetings to underline that it intends to be a supportive long-term investor, they said. Daimler had no immediate comment on any meetings. Geely and the German economy ministry declined to comment. Chinese investors in German technology companies have tended to take a consensual approach, buying incremental stakes in companies such as robotics firms Kuka and Kion, typically after long consultation with management and other stakeholders. In November, Geely asked Daimler to issue new shares so it could buy a stake, as a way to access Mercedes-Benz technology for electric cars and trucks, including battery technology, to help Geely comply with a Chinese crackdown on pollution. But the German company turned down the offer saying it did not want to dilute existing shareholders, sources at the time told Reuters. Li changed tactics, and quietly amassed a stake of 9.69 percent worth $9 billion at Daimler's current share price.
