The Mugen Shinden won Isle of Man’s TT Zero the last 3 years, holds the fastest Lap, and set a new race record, averaging 119.279 mph around the mountain course. Powered by Maxell batteries, the bike weighs 250kg(551lb) with 148hp and 162 ft/lb of torque. An impressive weight to torque ratio of 3.4:1
TT Zero lap speeds have been improving at an average rate of around 4 mph each year since the series began (119.279 mph as of 2015), and thus could achieve 130 mph by around 2020, nearly equalling the top super bikes of the world (current record 133.393mph).
For comparison, other bikes or cars with 148hp & 162 ft/lb torque:
2014 Triumph Rocket III Roadster 2294cc 809lb weight to torque ratio of 5:1
2016 Vauxhall Adam S 1400cc turbocharged 2597lb weight to torque ratio of 16:1
1998 Mercedes C-230 2300cc 3250lb weight to torque ratio of 20:1
That’s a lot of tire shedding power on one wheel on such a light bike, and electric puts all that torque down all the time!
Putting into a car’s perspective, the diminutive (and least expensive of <50K cars) Chevy Spark EV’s 327 ft/lb of torque can snap a head back harder than a 2015 Dodge Challenger SRT 392 and a host of other muscle cars.
