A couple of days ago, Chevrolet introduced Bolt, the new, affordable electric car, however only few technical details were mentioned. Now, further specifications regarding Bolt's powertrain are finally available for the curious fans.

According to Chevrolet, the engineers have been instructed to develop the kind of powertrain that will also deliver "a delightful driving experience". The center of the car represents the electric motor with permanent magnets, powering the front wheels. The motor produces 150 kW of monitoring power and up to 360 Nm of torque. Combined with a 7.05:1 final drive ratio, the Bolt accelerates from zero to 100 kmh in less than than seven seconds. Accelerating stops at 145 kmh.

Power delivery is controlled by Chevrolet's first Electronic Precision Shift system controls the power delivery. Based on drive mode selection and accelerator inputs, the system sends electronic signals to manage precise feel and delivery of power and torque. Such system, of course, requires less space than a traditional mechanical shifter, which means there is more freedom in creating a spacious and comfortable interior.

Cooperating with experts from LG Electronics and relying on past experience with Volt, Chevrolet Engineers developed a new 60 kWh battery pack with maximum power output of 160 kW. The battery system, which occupies the entire bottom space of the car, weighs 435 kg and consists of 288 lithium ion cells, arranged in 10 modules and 96 groups of three cells per group. The basic overnight charging – in the US – is possible via a 120 V husehold charger, however, via a standard equipment 7.2 kW onboard charger with a 240-V wall box the batteries can be charged in less than two hours to secure a further 80 kilometers of range. After 30 minutes of fast charging, the car is able to travel for another 145 kilometers.
