“Green Envy” is an electric streamliner motorcycle, and it is being built to become the world’s fastest motorcycle. Period! Green Envy is the successor of the KillaJoule, which is currently the world’s fastest electric motorcycle at 270mph (434 km/h). Just like the KillaJoule, Green Envy it is being built by me (Eva Hakansson), my husband Bill Dubé, and a team of volunteers. Bill and I are both mechanical engineers; I have a PhD in mechanical engineering, while Bill has a bachelor degree in mechanical engineering and a PhD in Applied Physics. We love to build things that have never been built before! You can read the whole story about me, including how I met Bill here.
Green Envy is a battery-powered, streamliner, sidecar motorcycle and it looks very much like the KillaJoule. However, there will be some major differences. First off, Green Envy is – of course – green instead of red. It also has more than twice the power, the target is over 1000 horsepower (preferably 1 megawatt = 1360 HP). It is being built with the goal to be the world’s fastest motorcycle. Period.* In order to fit the larger drivetrain, the Green Envy is about 5 ft (1.5 m ) longer than the KillaJoule, which means about 23 ft or 7 m. The cross-sectional area is a tiny bit bigger, and the aerodynamics are improved and will be improved further. There are also be a lot of subtle changes improving performance, handling, and reliability. Or simply speaking, we learned from all the mistakes we made building the KillaJoule. 😉
The Green Envy has been constructed in New Zealand and was ready for race in February 2020. It was shipped to Australia to be raced at the Lake Gairdner salt flats in Australia in March 2020. Then the big virus outbreak hit…. It is currently uncertain where its debut will be, but we are looking at all possible venues to let is stretch it wheels!
The Green Envy was built in record speed. On July 30, 2019 the high strength steel tubes for the frame were laser cut by Mulcahy Engineering in Auckland, New Zealand. 6 months and 22 days later we loaded it in a container and sent it to Australia. Such a fast build is almost unheard of; it typically takes several years before a scratch built vehicle like this is on its wheels. However, there is still room for much improvement, and we will within a year or two be looking to replace the battery pack (it was transferred over fro the KillaJoule).

* As of July 2017, the overall motorcycle record is 376 mph (605 km/h), held by Ack Attack and Rocky Robinson.
Specs Green Envy:
Power: Current ~1,000 HP. The final target is 1 megawatt (~1300 HP). [3 times more than in the KillaJoule]
Motors: Two (2) AVID EVO AFM240-3 motors, capable of 500 HP each. Permanent magnet, AC motors.
Inverters: Four (4) Cascadia Motion PM100DX inverters
Battery voltage: ~400 V [Same as the KillaJoule].
Battery capacity: 20 kWh.
Battery chemistry: Lithium-ion-iron-nano-phosphate by A123 Systems.
Frame: Chrome-moly steel tubes, laser cut by Mulcahy Engineering, welded by Axis Industrial. [Same as the KillaJoule]
Bodywork: Combination of aluminum sheet metal (for single curved surfaces) and 3D printed and/or composite parts (for complex curved surfaces). [Similar to the KillaJoule, but more 3D printed parts expected].
Wheels: Non-pnematic wheels, currently under development. Goodyear pneumatic LSR tires as Plan B and for initial testing.
Front suspension: Springer-style front suspension. [Same as KillaJoule]. Suspension components from Öhlins.
Steering: Side-sticks connected to the springer-style fork. [Same as KillaJoule].
Rear suspension: Stereo suspension. Suspension components from Öhlins.
Length: ~7 m (23 ft). [1.5 m / 5 ft longer than the KillaJoule]
Height: ~1 m (~40 inches) [About 2 inches taller than to the KillaJoule]
Width: ~0.6 m (22 inches) [2 inches wider than the KillaJoule]
Weight: 1200 kg (2500 lbs) [Close to twice the weight of the KillaJoule due to the larger drivetrain, larger frame, and more safety features]

Timeline (has to be very much revised due to the virus outbreak….):
2019: Construction, in Auckland, New Zealand.
March 2020: First start at Lake Gairdner salt flats, South Australia, Australia under the sanctioning of the Dry Lake Racers of Australia. The goal is to make a safe, successful run and keep the rubber side down and the shiny side up. A speed of 200+ mph would be considered a success. Anything higher than that would just be bonus!
August 2020: If time and budget allows, it would be possible to race the Green Envy at Bonneville as well, but that would require very generous sponsors.
March 2021: Back at Lake Gairdner salt flats, Australia. Target: 300+ mph, perhaps even 400+ mph if the planets line up and the angels are singing. (Yes, everything has to work perfectly for this to happen, that’s why it takes so long to prepare).
