The BMW M8 leads this month's list of discounts

Back in June of this year, the BMW 8 Series was the most heavily discounted vehicle in America. This month, it's the 617-horsepower M8. Midsummer buyers of the 2020 BMW M8, which is offered in hardtop, convertible and four-door Gran Coupe bodystyles, were seeing an average of $6,150 cut off the sticker; this month that figure has ballooned all the way to $16,864. That's more than 11% off the car's $150,000-plus retail price, and, according to data provided by TrueCar, it's the largest dollar amount sliced off the retail price of any car for the month of September. Next is the Maserati Quattroporte, buyers of which are saving $15,912 for an average transaction price of $99,763. If that's still too expensive, the smaller Ghibli's $70,030 average transaction price represents a huge 14.5% discount, earning the Italian sedan entry into our monthly top 10 best deals list.  The third largest monetary discount in September comes off the $131,066 sticker price of the lovely 2019 Mercedes-AMG GT. Take $15,473 off that sum for an average transaction price of $115,593.

Mercedes could make EV batteries with Audi, BMW

It's not a big leap from digital maps to batteries, it turns out.The head of Mercedes-Benz parent Daimler said recently that he envisions his company working together with German automotive competitors BMW and Volkswagen to further accelerate electric-vehicle battery technology. The three automakers recently worked together to enhance their in-car maps systems. Daimler CEO Dieter Zetsche talked about "commonalities" between automakers, not the least of which is the need for all of them to achieve increasingly stringent fuel-economy requirements in the European Union, at the Frankfurt Auto Show last week, according to Reuters. While these companies have made their own inroads as far as plug-in vehicles go, they are all behind the Renault-Nissan Alliance when it comes to public deployment of electric vehicles. This summer, Daimler, Audi and BMW hooked up to acquire the Nokia Here digital-mapping service for about $2.8 billion. The triad of automakers beat out companies such as Apple and Uber to buy the entity, which was founded in 1986 as Navteq. Nokia bought the company in 2007. The acquisition makes sense as the automakers work on improving their products with features like cloud-based data to warn drivers of icy roads and traffic jams. The technology will likely also eventually be used in autonomous vehicles. Automakers working together for a common goal of improved technology is nothing new, of course. General Motors and Honda agreed in 2013 to work together to accelerate hydrogen fuel-cell drivetrain development. Earlier that same year, Daimler said it would work with Ford and Nissan in a separate collaboration to speed up the development of hydrogen fuel-cell technology. Related Video:

2015 Mercedes-Benz S63 AMG Coupe

Conventional wisdom would dictate that adding more power and several key performance enhancements to an already very good car, like the 2015 Mercedes-Benz S550 Coupe, will end up equaling an even better car. In the case of the 2015 Mercedes-Benz S63 AMG Coupe, conventional wisdom sort of applies, but perhaps not as much as we'd have initially guessed. We'll get into the nitty gritty details in just a moment, but here's the most immediate takeaway we had in our minds as we walked away from this super coupe: The S63 AMG is excellent, but so is the slightly more mundane S550 Coupe on which it is based, and which is priced some $41,000 less expensive than its more powerful sibling. Chew on those figures while we examine what differentiates the two S-Class Coupes. Drive Notes As expected, the single greatest highlight of the 2015 S63 Coupe is its engine. As a powerplant, it's a gem. As a hand-built engineering exercise, its 577 horsepower and 664 pound-feet of torque are just as impressive in real life as they sound when recited from stat sheets. Not that the old CL63 AMG was lacking in power, but the new S63 AMG Coupe boasts 41 more horses and 74 more lb-ft than the outgoing engine. The run to 60 miles per hour takes a scant 3.9 seconds, according to M-B, aided in no small part by the car's 4Matic all-wheel-drive system and other assorted electronic brains deciding where, exactly, all those ponies should be sent. The rear-biased system is tuned to send two-thirds of the engine's power to the rear wheels in a bid to make the car feel more like what performance-minded drivers expect. Top speed is electronically limited to 186 miles per hour, which is plenty fast enough, even in the days of 200-plus-mph sedans from M-B's former corporate cousin Dodge. We didn't get anywhere near the car's maximum velocity, but our brief trips into triple-digit territory were quiet, comfortable and completely free of drama. The seven-speed automatic gearbox responds quickly to requests of your right foot, but the steering wheel-mounted paddles don't change gears as quickly as we'd like when in Manual mode. Controlled Efficiency (which we'd call Comfort) maximizes efficiency, keeping the transmission in higher gears and shifting earlier than when in Sport mode, and we didn't find much fault with the computer's shifting algorithms in either setting.
