  • American Favorite Sports Cars to Pace Belle Isle Grand Prix

    This weekend, two sporting events will come to Detroit – the Chevrolet Grand-Am 200 at Belle Isle on Saturday and the Chevrolet Indy Grad Prix on Sunday. The former will have a Chevrolet Camaro ZL1 pacing the contenders while the latter will get the Chevrolet Corvette 427 Convertible.

    “With Corvette and Camaro, Chevrolet has two of the most popular, and most iconic, performance cars in the industry,” said Chris Perry, vice president, Chevrolet Global Marketing. “It will be very exciting to see them leading the field as racing returns to Detroit.”

    Looking at the statistics, its clear that those two are the right choice – back in 2011, every third supercar sold in the US was either a Camaro or Corvette. This year, that trend is still up as total sales for Camaro lead its nearest competitor, the Ford Mustang, by 13 percent through April. For the same period, Corvette sales are 39 percent higher than its nearest competitor, the Porsche 911

    But we need other numbers to be convinced that the Camaro and Corvette are as appealing as they say. Fortunately, those numbers are present as well: The 2012 Camaro ZL1 Coupe which will have the job to pace the Grand Am is the most powerful one up to date – 6.2 liters of displacement, V8 cylinders, supercharged, it’s engine develops 580 hp and 556 lb-ft. of torque. It sounds raw, but it isn’t. The magnetic suspension is looked after by a sophisticated Performance Traction Management so that you have infinite amounts of grip. Then, even when the infinite comes to an end, the six-piston Brembo brakes to keep you out of trouble. As a result of all that, the Camaro ZL1 goes from 0 to 60 mph in 3.9 seconds and has a top speed of 184 mph. It’s current record at the Nürburgring stands at 7:41:27.

    Similarly to the Camaro, the 2013 Corvette 427 is the most powerful convertible Chevrolet out on the markets. In fact it’s one of the most powerful convertibles in general. It has an engine from the Corvette Z06 which erupts with 505 hp and 470 lb-ft. of torque every time you step on it. Because of extensive use of carbon fiber, the 427 is lightweight as well – 3,355 pounds. (for a convertible). That means a power-to-weight ratio of 6.64 – or one horsepower for every 6.64 pounds of vehicle mass. That puts to shame well-established brands such as Audi, Aston Martin, Ferrari and their respective convertibles. For the Chevrolet Corvette 427 to do a 0 to 60 mph run it takes 3.8 seconds and the top speed boarders 190 mph.

  • 2013 Corvette 427 Convertible – Rare and Commemorating

    Chevrolet have announced that a 2013 Corvette 427 Convertible Collector Edition will make it’s debut on January the 21st and will go on sale this summer. This is big news for we are talking about the first Chevy ever, that can be both a collector and a commemorative edition at the same time Yes, Chevrolet are celebrating their 60th birthday this year and what better way to mark the occasion than producing a convertible, more powerful than the gravity of Jupiter.

    Under the hood one can find an LS7, 7.0 liter (427 cubic-inches) engine, rated at 505 horsepower (377 kW) which sends 470 lb.-ft. of torque (637 Nm) trough a compulsory 6-speed manual. The connecting rods in the LS7 are all titanium and so are the intake valves while high-flow cylinder heads and a dry-sump oil pump add to the performance. The 427 is rear-wheel driven just like the Z06, the battery is at the back for better weight distribution and it comes with a Magnetic Selective Ride Control so the suspension is clever too. The front 19-inch and back 20-inch machine-face Cup wheels (ZR1 Black Cup or chromed also available) are fitted with ZR1 Michelin PS2 tires. To save weight, the hood, fenders and floor panels are all made from carbon fiber. That diet has resulted in the Corvette weighing only 3,355 pounds (1,522 kg) which by itself means a power-to-weight ratio of 6.64 – or one horsepower for every 6.64 pounds of vehicle mass. That’s more power than any other convertible can offer including the Ferrari California Convertible, the Audi R8 5.2 RSI Spyder, the Aston Martin DBS Volante Convertible and even the Porsche 911 Turbo S Cabriolet. Predictions suggest a 0 to 60 mph sprint time of just 3.8 second and top speeds exceeding 190 mph.

    For the commemorative spec on any Chevrolet, one does need to opt for the 60th Anniversary Package which includes a color theme of “Arctic White” on the outside with Blue Diamond leather seats inside and gray-painted brake calipers. Convertibles will also get a blue rooftop. Other enhancements include a ZR1 rear spoiler, a “CFZ” carbon fiber front splitter and rocker panels and branding on various places to let you know you are driving a novelty. If one feels the need to spend even more money a graphics package includes racing stripes that slice trough the whole car while a Build Experience option allows customer participation in the construction process of the vehicle… which, doesn’t make any sense if the customer is as inapt as me when it comes to technology.
