2014 Mercedes-Benz SLS AMG Black Series [w/video]

The biggest misconception about the Mercedes-Benz SLS AMG Black Series is that it's simply a higher-performing version of the SLS GT - a closer look, or better yet, a few hot laps on a high-speed racing circuit, reveals that is anything but the case.
Launched in the States in mid-2011, the standard SLS GT is a 583-horsepower, all-aluminum, gull-wing coupe with performance that positions it near the top of the exotic segment. While the AMG team at Mercedes-Benz could have left it alone, their experience with the SLS AMG GT3 race car said there was room for improvement, so they devised the SLS Black Series. The transformation from SLS GT to SLS Black Series is extensive, with no fewer than 17 different significant enhancements.
The engine mapping, crankshaft, connecting rods, valve-train, intake, exhaust and cooling are all modified and the engine's redline bumps up from 7,200 to 8,000 rpm, which pushes output of the hand-built 6.3-liter V8 to 622 horsepower. The power steering receives a new ratio, a coil-over AMG Adaptive Performance suspension is installed along with underbody braces, the track is widened, two-piece carbon-ceramic brakes replace iron rotors at each corner and a lightweight titanium exhaust is fitted beneath. The AMG Speedshift seven-speed dual-clutch gearbox is modified and an electronically controlled AMG rear differential lock ensures the power goes to the pavement. Last on the mechanical upgrades are new lightweight forged wheels (10x19 inches front and 12x20 inches rear) wrapped in special R-compound Michelin Pilot Sport Cup tires.

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.

Mercedes-Benz GLE gets official before NY Show

Hot off the debut of the GLE-Class Coupe just a few months ago at the Detroit Auto Show, Mercedes-Benz is now all set to unveil that SUV's more utilitarian sibling. The new GLE-Class will offers buyers a model that's a little more traditional looking, while still bringing heaps of available power and luxury to the table. The new GLE-Class replaces the ML-Class in Mercedes' newly renamed lineup. At the front, there's a new nose with a clear family resemblance to the Coupe. It sports big openings all over, and standard models wear an attractive two-bar grille or a just a single crosspiece for AMG trims. Once your eye moves past the A-pillar, the design becomes more of an evolution of the current ML. The prominent C-pillar and wraparound rear glass are still present, while the creases running down the profile appear a little sharper and more pronounced. As you might expect, the interior for the GLE-Class is practically identical to its Coupe counterpart. That means drivers get a thick, multi-function steering wheel to hang on to, and there's a large infotainment display poking up above the dashboard in the center. A center-console-mounted dial controller is found below. When it comes time for buyers to pick their GLE-Class, they're going to have a long list of powertrains to choose from. Lowest in terms of horsepower is the GLE300d 4MATIC with a 2.1-liter, four-cylinder diesel making 201 hp and 369 pound-feet of torque. Next, there is the gasoline-fueled GLE350 with a 3.5-liter V6 making 302 hp and 273 lb-ft, and it's also available with 4Matic. The GLE400 4Matic uses a twin-turbo 3.0-liter V6 to make 329 hp and 354 lb-ft of twist, and the GLE550e 4Matic adds a plug-in hybrid to that mill to bring total output to 436 hp and 479 lb-ft. Finally, for those that really want some power underfoot, the Mercedes-AMG GLE63 and GLE63 S boast twin-turbo 5.5-liter V8s putting down 550 hp and 577 hp, respectively. The standard models all use versions of the 7G-tronic gearbox, and AMG models get the Speedshift MCT seven-speed. We look forward to getting a good look at the GLE-Class at its grand unveiling at the New York Auto Show on April 1. The posh SUVs start arriving at dealers a few months later in August. Buyers wanting the GLE550e 4Matic have to wait just a little longer until it comes along in mid-September.
