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.

France formally moves to ban Mercedes vehicles using contested refrigerant

That didn't take long. Shortly after a French administrative court gave the French government a ten-day window to reconsider its ban on registrations of Mercedes-Benz A-, B- and CLA-Class cars using the prohibited R134a refrigerant, the government cited an EU directive to formalize banning the sale of the cars. The country's environmental ministry said that registrations "will remain forbidden in France as long as the company does not to conform to European regulations," meaning so long as they do not use the approved R1234yf refrigerant.
Daimler had won the administrative court decision by challenging France's application of a "safeguard" provision in which the EU allows a country to block sales of cars that would "seriously harm the environment." In spite of Daimler's victory, France has cited that very provision as basis for the continuation of the ban.
Daimler got permission from Germany's KBA federal motor authority to keep selling cars with the coolant banned by EU politicians, and is using that national permission as the right to sell the cars throughout Europe. Meanwhile, above that battle, German politicians are asking the EU to let Mercedes sell the cars in France while the KBA does more testing, at the same time as the EU is threatening Germany with repercussions if it doesn't bring the KBA and Daimler into line.

Hamilton wins at Monza, takes Formula One lead from Vettel

MONZA, Italy (Reuters) - Lewis Hamilton won the Italian Grand Prix for Mercedes on Sunday with an utterly dominant drive that sent the Briton clear at the top of the Formula One world championship for the first time in a year. The triple champion, who started the last race of the European season from a record 69th career pole position, led Finnish team mate Valtteri Bottas to a runaway one-two finish at Ferrari's home track. "I love it here in Italy and I love the passion of the fans," Hamilton declared on the podium jutting out over a sea of red-shirted Ferrari fans, with plenty of boos coming his way amid the cheers. "We did a great job, the team did an exceptional job this weekend," he added. "Mercedes power is definitely better than Ferrari power." Ferrari's Sebastian Vettel, who had led the standings since he won the Australian season-opener in March, finished third in the final race of the European season and 36.3 seconds behind the winner. Bottas was 4.4 adrift of Hamilton. "It was a difficult day, a difficult start," said Vettel. "My race was fairly isolated, we tried to keep as close as possible but we simply didn't have the pace... You could say it's a bad day but I know the team is on the right way... so I am in a very positive mood despite the numbers." Hamilton is now three points clear of the German, with seven races remaining. Mercedes are 62 points clear of Ferrari in the constructors' standings. The first driver to win two races in a row this season, with Monza following on from Belgium a week ago, Hamilton now leads Vettel 6-4 on victories in 2017. He has 238 points to Vettel's 235. The last time Hamilton led the standings on his own was at Monza a year ago, with now-retired team mate Nico Rosberg emerging as the eventual champion. FEW THRILLS Hamilton and four-times champion Vettel were level on points this year after China in April, with one win and one second place each. If Sunday's race was a dull affair, there was at least plenty of sunshine in marked contrast to the steady rain that drenched fans and delayed qualifying for hours on Saturday. Hamilton pulled away cleanly from his historic pole, and fourth in a row at Monza, and was never challenged as he drove to the chequered flag with the minimum of fuss. It was his third Italian Grand Prix win in four years and 59th career victory – only Michael Schumacher, whose pole record he beat, can boast more – and few have been more straightforward.
