Bosch has extended its connections with ecologically-friendly motorsport by supplying the powertrain for a new 'e-kart' prototype.
Developed in conjunction with FIA Electric, the New Energy Commission, the German Motorsport Association (DMSB) and Germany’s largest kart manufacturer Mach 1 Kart, the e-kart prototype uses two starter-generators developing a total 20W and 300Nm to power the rear wheels.
The e-kart uses much of the technology developed for the company’s BRS boost recuperation system due to go into production in 2017 as a supplement to regular reciprocating-engine powertrains.
Energy is stored in a 48-volt lithium-ion battery that can be re-charged through a custom ECU that directs energy flow around the kart’s systems to extend its operational range.
Performance is not an issue: Bosch says that because maximum torque is available from very low engine speeds, the e-kart is able to squeal the tyres with just a tap of the pedal. It says the only things missing are the sounds and smells of a regular racing kart.
Bosch also supplies technology to the FIA-sanctioned Formula E championship that has been operating since 2012 and comprises a field initially made up of electrically-powered open-wheelers supplied by Spark Racing Technology. The organisers are keen to see other suppliers enter the series.
Speaking about the e-kart prototype, vice-president of Bosch Motorsport Dr Klaus Böttcher said: “Even during its initial run, the electric kart was able to hit 100km/h in less than five seconds and achieve a top speed of over 130km/h.
"Over the coming weeks and months we will continue testing to further explore the capabilities of the new e-kart.”
DMSB General Secretary Christian Schacht is also enthusiastic about the electric racing kart: “We’re happy to support the forward-looking and exciting FIA electric kart project.
"As an advanced technology nation, Germany very much has a special obligation to support electro mobility in motorsports. We do that with Formula E, and we also do that by supporting junior kart racing drivers.”
Nobody is speculating yet on a date for racing e-karts becoming an operational reality after the prototype makes its official debut in Berlin.
It does seem inevitable though. And when it happens, will it mean future go-kart competition becomes a bit like a field of sideshow dodgem cars jostling for position at high speeds on the racetrack?
For many reasons, hopefully not.
