2017 Mercedes-AMG C63 Cabriolet Lets You Do 186 MPH with the Top Down


http://st.automobilemag.com/uploads/sites/11/2016/03/2017-Mercedes-AMG-C63-S-Cabriolet-front-in-motion-02.jpg?interpolation=lanczos-none&fit=inside%7C820%3A471&crop=820%3A471%3B%2A%2C%2AThere’s just something special about top-down motoring, especially when you have a high-performance V-8 to motivate your convertible. At the New York auto show, Mercedes-AMG is upping the ante on its C-Class Cabriolet with a new C63 version that promises as much as 186 mph of hair-rustling fun.
The 2017 Mercedes-AMG C63 Cabriolet follows the same basic strategy as the sedan and coupe versions. There’s a 3.0-liter twin-turbo V-8 engine up front, a seven-speed automatic in the middle, and a limited-slip differential putting power to the rear tires. In the standard C63, the engine makes 469 hp and 479 lb-ft of torque, sending the droptop to 60 mph in 4.1 seconds and on to an electronically limited top speed of 155 mph. Upgrade to the C63 S and those figures become 503 hp, 516 lb-ft, 4.0 seconds, and 186 mph.
Besides the engine, the 2017 Mercedes-AMG C63 Cabriolet also scores an upgraded chassis, with wider front and rear tracks beneath flared fenders, unique suspension components, three-mode adaptive dampers, and 18- or 19-inch wheels, depending on model. The C63 comes with a mechanical limited-slip diff while the S gets an electronically controlled unit that is said to provide “even more sensitive and faster control.” The S also receives dynamic engine mounts that can soften during cruising to improve comfort, or stiffen during aggressive driving for more precision.
With all that power on tap, serious brakes are needed to haul the C63 Cabriolet back down to a stop. C63 models get 14.2-inch front discs and the S models get 15.4-inch front discs; an optional carbon-ceramic setup has 15.8-inch front stoppers, which also have half the unsprung weight of the standard brakes. Options include an AMG Performance two-mode exhaust, carbon-fiber exterior trim pieces, a head-up display, and a safety package that includes features like pre-collision braking and lane-keep assist.
To help launch the 2017 Mercedes-AMG C63 Cabriolet, there will also be an Edition 1 version painted in Cashmere White Magno, with the rear lip spoiler and exhaust tips finish in gloss-black. Inside, the Edition 1 treatment entails Nappa leather seats with brown/black design and gray stitching, as well as a flat-bottom steering wheel wrapped in black Nappa leather.
Within the C Cabrio lineup, the C63 fits above the base 241-hp C300 and the 362-hp AMG C43. Based on how much you’ll pay for other versions of the C63, the Cabriolet won’t come cheap. Expect a sticker somewhere close to $70,000 when the car hits U.S. dealers this fall.

Godzilla by the Numbers: 2009-2017 Nissan GT-R

A look at the ever-evolving Japanese supercar

Since it arrived on the U.S. scene for the 2009 model year, the Nissan GT-R has seen continual improvements. For 2017, the Japanese supercar gets even more updates. While most updates focus on aesthetics and comfort, Godzilla also gets another power boost for its latest refresh. Here is a look at the Nissan GT-R’s performance evolution through the years.
When the R35-generation Nissan GT-R arrived in 2009, its twin-turbocharged 3.8-liter VR V-6 was rated 480 hp and 434 lb-ft of torque. A six-speed dual-clutch transmission combined with the automaker’s ATTESSA E-TS all-wheel-drive system and advanced electronics routed power to all four wheels. The first R35 Nissan GT-R we tested hit 60 mph in 3.2 seconds and finished the quarter mile in 11.6 seconds at 120.0 mph. More than a one-trick-pony, the GT-R lapped the figure-eight in 24.3 seconds and pulled 0.97 g average around the skidpad. Those numbers were mighty impressive for its day, but the GT-R wouldn’t stop there.
The GT-R received its first power boost in 2010 and now made 485 hp. In 2011, Nissan also added a new transmission control unit and updated the suspension tuning, which made a noticeable difference in handling. The figure-eight lap dropped to 23.7 seconds, while the skidpad number climbed to 1.03 g. In 2012, the GT-R got a massive power boost, which increased horsepower by 45 and torque by 14 for totals of 530 hp and 448 lb-ft, respectively. Acceleration and handling both improved, as did handling.
2011-nissan-GT-R-front-end
Not about to leave well enough alone, Nissan increased horsepower another 15 to 545 hp and torque by 15 to 463 lb-ft for the 2013 model year. The GT-R also gained revised suspension tuning. Our long-term 2013 Nissan GT-R Black Edition now accelerated to 60 in 2.8 seconds. The figure-eight time dropped to 23.0 seconds flat.
A new Track Edition was introduced in 2014 and ditched the rear seats in search of weight reduction. The new model featured a stiffer suspension and new Dunlop SP Sport Maxx summer tires. In 2015, Nissan introduced the hardcore GT-R NISMO model with even more power and wilder aerodynamics. While lesser GT-R models still make 545 hp and 463 lb-ft, the GT-R NISMO makes an astounding 600 hp and 481 lb-ft. That’s an increase of 55 hp and 18 lb-ft. In testing, the 2015 Nissan GT-R NISMO posted a best acceleration run of 0-60 mph in 2.9 seconds and a quarter mile in 11 seconds flat at 126.6 mph. The figure-eight time dropped to just 22.9 seconds.
The last example we tested was a 2016 Nissan GT-R 45th Anniversary model (545 hp and 463 lb-ft) that felt much softer than early models. That model came in last place in a comparison against the Mercedes-AMG GT S and Porsche 911 Turbo S.
Performance updates to the 2017 Nissan GT-R include a boost in power to 565 hp and 467 lb-ft (increases of 20 hp and 4 lb-ft). Additionally, power under the curve is also said to be stronger. Nissan also revised the transmission for smoother shifting in normal driving, while still being aggressive during performance situations. Other updates include a stiffer frame and revised suspension. These changes apply to the standard 2017 GT-R. Only time will tell if Nissan will also update the hardcore GT-R NISMO model.
While we won’t know how the newest model performs until we can test an example at the track, we suspect it will continue the GT-R’s history of gradual performance increases. Until we get our hands on a 2017 model, take a look at how the GT-R has performed in testing in this chart.
Model HP Torque 0-60 1/4 mile Trap Speed 60-0 Skidpad Figure-eight time
2009 Nissan GT-R 480 434 3.2 11.6 120.0 105 0.97 24.3 sec @ 0.81 g

2016 Nissan GT-R 45th Anniversary 545 463 2.9 11.2 122.0 103 1.0 23.5 sec @ 0.90 g
So how has the Nissan GT-R stacked up against other supercars? Going by just the stats from our first five World’s Greatest Drag Races (spun off from 2011-2015 Best Driver’s Car competition), the Nissan GT-R has had a strong showing. Godzilla has claimed four spots on our list of the top 10 quickest cars from the past five drag races. In fact, that’s one for each of the four years the GT-R has participated in the competition. See where the GT-R stands in terms of acceleration in the chart below.
Finishing Order Competition Year Vehicle Elapsed Time Trap Speed
1st 2012 Lamborghini Aventador LP 700-4 10.8 seconds 132.3 mph
2nd 2012 McLaren MP4-12C 10.8 seconds 130.7 mph
3rd 2014 Porsche 911 Turbo S 10.9 seconds 126.0 mph
4th 2013 Nissan GT-R Track Edition 11.0 seconds 125.1 mph
5th 2013 Mercedes-Benz SLS Black Series 11.1 seconds 129.8 mph
6th 2014 Nissan GT-R Nismo 11.1 seconds 125.3 mph
7th 2012 Nissan GT-R Black Editon 11.1 seconds 124.8 mph
8th 2011 Nissan GT-R 11.2 seconds 121.8 mph
9th 2013 Audi R8 V10 Plus 11.3 seconds 125.8 mph
10th 2011 Ferrari 458 Italia 11.3 seconds 125.6 mph
Of course, we can’t mention the Nissan GT-R without talking about its not-for-U.S.-consumption forebears. To many car fans, the Nissan Skyline GT-R has been the sweetest kind of forbidden fruit, with its turbocharged straight-six power and performance-oriented all-wheel-drive grip. Though we in the U.S. never got the chance to experience the Skyline GT-R, Nissan recognizes its contribution to the GT-R we know today, and is displaying every generation of GT-R at its New York auto show booth. Check out the photos below.
