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.

Mercedes-AMG once again joins forces with Cigarette Racing

Any time there's a new loins-quaking Mercedes-AMG introduced, you need to keep your eye on the aquatic horizon around the time of the Miami International Boat Show for the Cigarette tie-in to come roaring into port. The SLS AMG had its 2,700-horsepower, 46-foot Rider, the C63 AMG Black Series got a 1,350-hp, 50-foot Marauder, the G63 AMG got a 1,750-hp, 43-foot Huntress, and the SLS AMG E-Cell got a matching wild yellow 2,200-hp, 38-foot electric concept boat. Now that we're in 2015 with another AMG and another boat show, we have another Cigarette. Mercedes hasn't dropped the goods on this one yet, but it will be twins with the AMG GT. After that, we're guessing it will have a can't-miss-it paint job, be in the 40-foot range, and have something like 2,000 hp. The show is February 12-16, we'll have all the info for you then.

2017 Infiniti QX30 First Drive

If you've heard anything before about this car, the 2017 Infiniti QX30, it probably has to do with its corporate parents, an odd couple if there ever was one. Renault-Nissan, Infiniti's corporate overlords, inked a deal with Mercedes-Benz to share some mechanical components and platforms. That deal put a new, very modern 2.0-liter turbocharged inline-four under the hood of the Q50 and was the genesis of what you're looking at here. What are you looking at here? We drove this car in 2015, when it was called a Q30 – originally it was going to be the lower-riding counterpart to the slightly jacked-up QX30. Then Infiniti decided it'd make more sense to sell all variants of this vehicle as CUVs in the US, so we have three slightly different flavors of the QX30 instead. There's the normal version; the Sport, which is 0.6 inches lower; and the AWD, which is 1.2 inches higher. Infiniti brought us to Seattle to sample the Sport and AWD flavors on a semi-circumnavigation of the Puget Sound. It didn't rain a drop, thanks for asking, and instead was sunny and mild the whole time. It's easy to make the QX30 sound more confusing than it actually is. This is essentially a Mercedes-Benz GLA250 with full exterior styling and partial interior design by Infiniti, built in the UK alongside several other Nissans. The powertrain and chassis, including the optional AWD system, were all "co-developed" with partner Daimler, with final calibration and tuning by Infiniti engineers. Here's another way of explaining it: Infiniti needs an entry-level car to appeal to new premium car shoppers, and the QX30 is the prescription. It's a hatchback that's been given the mildest of CUV treatments and a lot of marketing descriptors. That's because hatchbacks are sales death in America. In Europe, they'll see right through the CUV posturing and realize it's just a hatchback offered in three different suspension heights. Whatever you call it to make it palatable to Americans, it's a useful little vehicle. This car is mechanically identical to the Q30, so there are some things we can gloss over. Both are powered by a transverse-mounted 2.0-liter Mercedes inline-four. It's a turbocharged, direct-injection gasoline engine, and it sure feels like one. It sounds like a rock tumbler full of nickels and runs out of breath at about 5,000 rpm. All versions make 208 hp at 5,500 rpm and 258 lb-ft of torque between 1,200 and 4,400 rpm – more than adequate but less than thrilling.
