Coming soon, ask Freaky parts if you want to buy one of these as it is his project. I don't know the all up weight but it is definitely going to be a lot less than 1/2 a ton inc batteries. Alloy brakes on order from FreakyParts Alloy shocks from Protech, no MX5 subframes, tubular wishbones for front and rear. Battery pack is 120 KWH Lithium Yttrium, our own BMS and charger, AC induction motor 4-1 diff. Looks like and Exocet but is actually very different, longer wheel base, lower front end, lower rear cover. No grille in the nose required as there is nothing to cool down!  |

Will the ac motor have a regen brake system that puts charge back into the battery like other electric cars ? I have put the link below on Teslas system in case nobody knows what it is. Most electric vehicles have the system, but as you probably know, is only found on A.C motors. www.tesla.com/en_GB/blog/magic-tesla-roadster-regenerative-braking%20Nottingham university also make the fastest electric super bike, this thing is a beast around the isle of Man |

To make this machine as efficient as possible I will be... Fitting a windscreen to aid aerodynamics. It makes a huge difference.  When we were in the wind tunnel we also swapped 225 tyres to 195's, a huge drag reduction. I have gone for 155's with low rolling resistance. Looking at the charts the Kumho's I have ordered got a C rating for efficiency. The wheels are 14" and are only 5" wide too so every little helps and they are light. The controller is fully programmable for regen when coasting. I can have a brake pot to save on brake pad wear and charge instead of waste when you use the middle pedal. Actually it only has 2 pedals so I mean the left pedal. I have exposed rear bones which don't look great as I don't have silencer to hide them. I made a make shift jig from an old wishbone, they look OK and the saving is a huge 2kg per side.  The jig is not exactly up to production standards but the clamps hold all parts tight during welding and the accuracy is OK considering we have rear track adjustment. Tube is 1"3/4 CDS with a 3 mm wall and 1" with a 3 mm wall, then a piece of 2"x1" to mount the shock plates and a piece of 20mm round as a bridge. |

Progress has been made on my "Evocet", but it has taken a few years to get to this stage! I have been toying with electric cars since I was about 10 and that was 50 years ago! Me and my Dad made a soap box cart with a lorry starter motor and 2 12v car batteries back in 1969, I remember riding it just after watching the news of a guy putting his foot on the moon! In fact Concord took it's inaugural flight about the same time as I took my first powered ride in my cart! Mine didn't make mach 3 though. If I had an MP3 player at the time I would have been listening to Mick Jagger singing Honky Tonk Women..... Now a days it seems the big boys are concentrating on providing customers with all the creature comforts they have become accustomed to but using batteries to power heated seats and A/C is a huge range buster. Tesla appear on face value to have it right, BUT they use over 7000 little (18650) batteries all linked together (same sort you have in your battery drill) powering a very heavy car. Then again if they didn't have heated seats and A/C they may not attract buyers. Add in the Tesla "ludicrous mode" and the car becomes great fun but hugely heavy on current and range reduction. So much current can be drawn that the batteries have coolant constantly pumped through ribbons to keep them from bursting into flames! The pump motor uses energy from what it is protecting.. Exocet is light and fun, we get away without having to install a heater as we have no roof! Perfect for EV version without wasting energy on those creature comforts that we can do without, weight decrease = range increase. Exocet could appeal to techy folk who become interested in what makes electric cars work. Maybe they will venture far enough to learn and build one. Meantime the carbon footprint created by my V8 Chevy will be more redressed when I get the Exocet finished. It's been in development for 50 years already! I will play a Jimi Hendrix CD whilst I work, 50 years ago he played Woodstock! "There must be some kinda way outta here, said the joker to the thief".........  |

Exocet, Evoset or Ecoset? Kind of like the latter myself.

Eddy is the other party. 0-60mph in 2.9 seconds ! Here is Eddy (company) talking about how it was made.

Here was the car at Hyperfest last year. Sorry for loads of posts, I am a huge EV fan.
