Mercedes-AMG GT attacks Circuit of the Americas

Mercedes-Benz is having a banner year with its Formula One team. Through 2014, the constructor has 454 championship points; ahead of its nearest competitor (Red Bull-Renault) by a margin of 182 tally marks. We're sure they can almost taste the champagne.
It's fitting then, and a little big cocky in a good way, that Mercedes has released a video of its newest sports car at an F1 venue. In this case, the car is the lovely Mercedes-AMG GT S, and the racetrack is Austin's Circuit of the Americas.
Having seen the official photo set and scratched the surface of the technical specifications earlier this week, we're excited to finally hear the thing run. As you might guess, the deployment of 503 horsepower and 479 pound-feet of torque from the twin-turbo V8 is a motivating experience. Crank up your volume, and hit that play button. (Oh, and Mercedes shot the thing in 4K, too, so those of you with expensive televisions/monitors should take heed to the settings.)

Comparison test: 2019 Acura RDX vs. compact luxury SUV competitors

Truth be told, if we were to compare the all-new 2019 Acura RDX with those compact luxury crossover SUVs it would most likely be cross-shopped against, you'd be looking at a different list. Even Acura admits that Lexus and Infiniti are the most likely bogies, but with the 2019 RDX, Honda's luxury brand is attempting to attract those customers who think as much with their hearts as with their heads. And for the most part, those folks have been buying from German brands: the Audi Q5, BMW X3 and Mercedes-Benz GLC-Class. So, to show how the new RDX compares to them, Acura actually provided examples of each during the recent press drive along with a Volvo XC60. All were determined to have greater emotional appeal than the last RDX, and we would certainly agree. For, as much as the previous-generation RDX made sense on paper, it was really hard to get excited about it. And when you're paying extra for a luxury vehicle, shouldn't you get a little excited? Well, as luck would have it, Consumer Editor Jeremy Korzeniewski and I were on hand in Whistler, British Columbia, for the press launch. We didn't have an abundance of time in each RDX competitor, but in conjunction with our usual comparison chart, our impressions should provide a good first taste of how the new RDX compares. Performance and fuel economy Contributing Editor James Riswick: On paper at least, the RDX is gutsier than its comparably powered European rivals. It also weighs the same or less, which logically should mean it'll be the quickest in a straight line. During my brief drives, though, I'm not sure it really stood taller than the three Germans. It at least matches them for smoothness, which is something that can't be said about the Volvo. Fuel economy is lower than them all when you consider all but the Mercedes come standard with all-wheel drive. It's also worth noting that all the competitors are available with engine upgrades, and unless Acura's forthcoming resurrection of Type S models includes the RDX, it should stay that way. Consumer Editor Jeremy Korzeniewski: Line 'em all up in a drag race, and I have a feeling the Acura would squirt away to victory. A good bit of that, though, would be due to its 10-speed automatic transmission, which offers a huge spread of ratios and fires off extremely quick shifts. In the real world, I'd guess fuel economy will be similar across the board, so I'm willing to call that category a draw.

Lewis Hamilton needs to step up in his 200th F1 race

LONDON — Lewis Hamilton will start the 200th grand prix of his Formula One career in Belgium this weekend, but the triple world champion has smaller but more significant numbers on his mind. Refreshed from an August break in the Caribbean, including a trip to Cuba in his role as UNICEF ambassador, the Mercedes driver is 14 points behind championship leader Sebastian Vettel as he revs up for the second half of the season. A fifth victory of 2017 for the Briton would put the pressure back on Ferrari's Vettel, and Hamilton can celebrate another milestone by bagging pole position on Saturday at the long and fast Spa-Francorchamps circuit. That would see Hamilton, who sportingly relinquished third place to team mate Valtteri Bottas in Hungary before the summer shutdown, match the record of 68 poles set by Michael Schumacher with Ferrari in 2006. Mercedes has won the last two Belgian Grands Prix, with now-retired 2016 world champion Nico Rosberg triumphant from pole last year after Hamilton won in 2015. Nobody will be taking anything for granted, however, after Ferrari's one-two win in Budapest at the end of July. "On paper, people will assume that Spa should suit our car because it is a circuit where aerodynamic efficiency is extremely important," Mercedes team boss Toto Wolff said. "But assumptions are dangerous — we have seen too many times already this season that the form book can be rewritten from one weekend to the next. So we will be making no assumptions." Hamilton has won twice before at Spa, as has Vettel, but the track — a classic blast from the past — has not been particularly kind to him. In 2008, when he won his first title, the Briton was demoted from first to third after the race for cutting a chicane, with then Ferrari rival Felipe Massa savoring victory instead. Spa can often be a lottery, with its capricious weather, and rain could be a boon for Red Bull's Belgian-born Dutch teenager Max Verstappen, who can count on plenty of local support in what amounts to a home race. "I just love the track and it'll be nice seeing so many orange (Dutch) fans in the grandstands," he said. "Spa is my favorite track of the year. You have to get everything right but when you get a good lap it's very rewarding." Belgium could also be good for Ferrari's Kimi Raikkonen, who arrives with a new contract for 2018 in his pocket.
