Hennessey Performance Reviews


Unbelievable! I couldn’t anticipate the power! It really is a fun car. I told you I live in a small town.., policeman pulled me over to see it and took a pic with him standing next to it.


I’ve been invited to the Corvette Roundup they do annually with neighboring cities, Cool Dessert Nights -which is a parade of cars with streets blocked off for classic cars to modern cars. I didn’t allow local tv station interviews lol


It’s a head turner! The day it arrived, it had to be delivered in a grocery store parking lot. There had to be 100 by-standers filming. I don’t have Facebook but it’s all over it.


My best feature is having the car in “rev” mode so when you downshift, it revs up the engine and that blowoff valve is my favorite sound!


Super happy! Thanks for additional goodies.


Best car ever!


Dear Hennessey, Can’t tell you how thrilled I am with the 750 build on my Camaro. You were completely right about it being the perfect balance between a driver and a beast. As I told you on the phone, on our way home, with the cruise control on and in Touring mode at 75 mph I was clocking 24 mpg. I was really surprised! It just glides down the road. It’s a wonderful road car when I’m cruising and a rocket ship when I get on it. Feels like the front end is lifting off! It was truly great to meet the crew at HPE and we enjoyed every minute of it. Please share this with:Dorothy, Jennifer, Kenzie, Mike, Donovan – for excellent work on the motor, and Alex for the GREAT – HOLY SHIT RIDE!!!! I plan to stop and see al of you next time I’m South.


Regards and my most sincere THANKS!!!


You have assembled an amazing team and I wouldn’t have considered this with any other shop. I have been reading all about your creations, on-line, and it’s obvious we share the same passions. If only I had your skill. Your team made my lifetime dream – of having the perfect car for me – come true. I couldn’t love it more. Keep up the great work and “BE SAFE, HAVE FUN AND GO FAST!!”

Customer Review: 2017 Mustang SS HPE750 - Hennessey Performance
Larry G and his 2012 Cadillac CTS-V Coupe HPE800 Upgrad

Dear Hennessey ,
I hope this email finds your business doing great . I know that people are quick to complain and very slow to say thank you , I choose not to be one of them . I dreamed all of my adult life to have a Hennessey product before I was to old to enjoy it and thanks to your staff it became possible . Two years ago today I received through all the snow storms in Texas and Georgia my 2011 CTSV as it arrived in Loganville . After starting in early 2013 looking at your website and then getting the nerve to call we found the car in Texas and bought it sight unseen and your team even went and picked it up . I flew down in June and agreed on the plan of attack and then it seemed that you contacted me in about August and gave me the unbelievable chance to be serial number 001 for the HPE800 supercharged unit and have my dash signed by you . I came down in late December to ride along with one of your drivers and my mind was blown away by the HPE800 performance and all the work and cost just seemed to be necessary in order to get that amazing product . I drive it often and never seem to get over loving it when someone looks in awe and ask is that really a Hennessey and I smile with humble pride and say yes it is and it was built just for me . THANK YOU . I have had little to no trouble now for two years with my car and may be a bigger fan than ever . Many/most people will talk about a dream car but you my friend turned my dream into a reality . I wish you much success .


Forever grateful

The car is awesome and the power is unbelievable. Hennessey did an outstanding job on turning my Camaro SS into a real hot rod. I have had people flag me down to look and take pictures of the car and engine then begging to go for a ride. It should be against the the law to have this much fun. Again an OUTSTANDING JOB!!

You guys did a great job. I just can’t get enough of driving my Vette. It attracts a lot of attention. People are always taking pictures and video of my car…it makes me feel like a celebrity!
