Formula Student has been part of the Czech Technical University since 2007, with CTU CarTech being the first ever Formula Student team in the Czech Republic. In 2010, the team split into two: CTU CarTech (constructing combustion race cars) and eForce FEE Prague Formula (focusing on EV‘s). Both teams have excelled in their fields, winning many awards over the year.This year the two teams have come together with one goal: to become one of the greates Formula Student teams in the world.

We are the first electric formula team in the Czech Republic. The 11th generation of the eForce Fee Prague Formula is FSE.11. With its powerful drivetrain and lightweight chassis, it can compete against any other FS electric team. Brand new powertrain combined with four in-wheel motors and a two-stage planetary gearbox, each motor controlled independently, produces the best on-track performance and is already prepared for DV class modifications.

Two Teams, Two Cars, One Challenge! We have made 3 cars with internal combustion motor and we made our first electric formula. History of CTU CarTech team has begun in 2009. After 2 years we managed to take part in Formula Student Electric. Our team has been personally splitted into two parts.Our Formula has hybrid tubular frame with aluminium sandwich panels. For traction we use custom developed three phase BLDC motor with it's own motor inverter. The power to is transfered by palanetary gearbox and chain gear. Motor and gearbox are placed in aluminium frame. Powerful LiPo batteries give us 400 A and 230 V. Baterries are placed in lightweight baterry pack. Self developed Control System based on Mbed microcontroller gives us very easy way how to create our wishes.Taking part in competition like this is big satisfaction for our work. Let's meet at Hockenheim!
