Robert Bosch GmbH has developed an “e-kart” producing 20 kilowatts from two motor-generators, and 300 Newton-meters (221 foot-pounds) of torque, a number Bosch refers to as “sporting.” It would be nice to know how much this cart weighs, but Autoweek relates, “The only thing Bosch isn’t saying for now is just how long the e-kart can run on that battery, assuming 10/10ths driving, and how much the battery and powertrain weigh.” Otherwise, we know the e-Kart goes from 0 to 100 kilometers per hour (62 mph) in under five seconds and can squeal its tires “with just a tap of the pedal.”  A guesstimate of 400 pounds for the total vehicle and driver weight would probably not be too far …

Bosch, the German electronics giant, is making a strong showing at the Frankfurt Motor Show (IAA), and showing off its solid-state Li-ion battery technology.  It recently acquired Seeo, Inc., an American startup that has been developing such a battery for several years, and will add Seeo’s research to its own expertise and exclusive patents. Encouragingly, the company says it will be able to double the energy density of Li-ion batteries while cutting prices by half.  Perhaps discouragingly, Bosch says this will take until 2020 to bring to production. Green Car Congress quotes Dr. Volkmar Denner, chairman of the board of management for Robert Bosch GmbH, claiming a breakthrough.  “Bosch is using its knowledge and considerable financial resources to achieve a …
