Chevrolet Camaro Z/28 is one of the best cars to drive nowadays. But what happens when it is equipped with Hennessey Performance HPE650 Upgrade? Unexpectedly OnStar calls you. Or at least this has happened to tuning company's owner John Hennessey, while he was testing the uprated Z/28 Camaro.
The people at OnStar gave him a call to make sure that everything was alright and he was safe. And he describes the experience: "No, I didn't crash while testing the car but I was pulling around 1.1 g's going around the sweeper turn at the end of our test track at Lonestar Motorsports Park. I guess they just wanted to check on me and make sure I was alright".
By the way, this doesn't happen for the first time, but he has already experience the same thing a few years ago. The difference was that he was test-driving the 700 HP Cadillac.
Now that's a very persuasive method to consider the HPE650 upgrade for the 2014/2015 Chevrolet Camaro Z/28, isn't it? If you have already decided that you want it then you should know that it will give your Camaro an output of 667 bhp (490 lb-ft) at 7,000 rpm!
To go into details, the upgrade includes the following: ported cylinder heads, upgraded valvetrain parts, HPE650 camshaft, stainless steel longtube headers, premium floor mats, serial-numbered dash and engine plaques, and Hennessey exterior badging.
