North American tuner Hennessey will produce 24 units of their upgraded 2010 HPE700 Camaro, which this time will be offered as a convertible.
The Hennessey Chevrolet Camaro Convertible will use a 6.2-litre LS9 V8 plant with power boosted to 755 bhp and 763 lb-ft of torque, figures that are enough to make it sprint from 0 to 60 mph in just 3.3 seconds.
The massive power increase results from a long list of modifications, which includes a supercharger upgrade, a custom cold air induction system, high flow fuel injectors plus an upgraded fuel system and intercooler.
At the exterior the Hennessey Chevrolet Camaro Convertible comes with carbon fiber components like front and rear bumpers, side skirts and rear diffuser plus 20 inch alloys, while the interior features leather seats, a limited edition plaque and embroidered head rests and floor matts.
Other upgrades like high performance brakes from Brembo, and a coilover suspension from KW have also been performed on the Hennessey Chevrolet Camaro Convertible.

LS9-Powered Camaro Goes Topless
New 2011 Hennessey HPE700 Camaro Gets Convertible Option and 755 Horsepower
SEALY, TEXAS – With the limited production run of Hennessey’s 2010 HPE700 Camaro long since sold-out, the company has announced they will build another 24 units for the 2011 model year. This latest run of HPE700’s will include the addition of the new convertible model (from Chevrolet) and an increase in power from its supercharged 6.2L LS9 V8 – the same engine found in the Corvette ZR1.
The 2011 HPE700 gets its additional power from revised boost levels and a more robust fuel system, delivering 755 bhp and 763 lb-ft of torque. This 30 horsepower increase over 2010 will also help move the convertible’s extra weight, while the large 15 inch brakes from last year remain to bring it back to a stop quickly.
As the Camaro convertible arrives in showrooms in the spring of 2011, the 6-speed manual SS model will become available alongside its hardtop brethren to become the basis for the HPE700 LS9 Camaro transformation.
HPE founder and president, John Hennessey said, "We have already sold a several of our 2011 HPE700’s in hardtop form, increasing the potential for the convertible LS9 Camaro to become an even rarer option than before". "I expect that we will sell all 24 units just as we did in 2010. However this time we will probably sell-out even sooner as the convertible option will certainly be attractive – especially with 755 horsepower".
In addition to the upgraded LS9 engine, the HPE700 also includes an adjustable coilover suspension, larger sway bars, HPE lightweight wheels, larger 15-inch brakes with 6-piston front calipers, stainless steel long tube headers, painted hockey stripe, Alcantara-wrapped steering wheel, CarbonAero™ carbon fiber body kit and more to complete the car’s distinct look and performance characteristics.
As with the 2010 model year, the 2011 HPE700 LS9 Camaro will be limited to just 24 units, with no set allocation between coupe and convertible. Pricing for the complete HPE700 upgrade, including the base vehicle, is $132,500 and can be ordered directly through HPE or one of Hennessey’s authorized Chevrolet dealers.
