Supercar manufacturer Koenigsegg has developed an electric motor and an electric vehicle drive unit that it hopes will be used in a number of third-party applications as well as its own cars.
The electric motor, named the ‘Quark’, is made out of 300M steel and produces the equivalent of 335bhp and 442lb ft.
Koenigsegg claims the 28.5kg motor has the best power-to-weight ratio in the industry.
The firm says it wants the motor to be used in a variety of applications, including electric vehicle powertrains, aerospace and the marine industry.
A version of the motor is set to be used in the Koenigsegg Gemera, which uses three of them mated to a twin-turbocharged 2.0-litre three-cylinder engine for a total output of 1700bhp.
“The Quark is unique in its high efficiency in combination with its class-leading torque-to-power-to-rpm-to-weight matrix,” said CEO Christian von Koenigsegg.
“This means, when using the Quark in applications such as marine, aircraft or VTOL [vertical take-off and landing aircraft], there is no need for a step-down transmission. Instead, direct drive can be achieved, as the RPM of the motor is right from the get-go.”
Koenigsegg also revealed its own Terrier electric vehicle drive unit, consisting of two Quark motors and its compact inverter, called ‘David’, which was first detailed last year.
The drive unit – named Terrier due to its “small, energetic and fearless demeanour”, according to Koenigsegg – is described by the firm as the “the most power/torque-dense, torque-vectoring drive unit in the EV industry”.
The lightweight drive unit weighs 85kg and produces the equivalent of 670bhp and 811lb ft. Its design means the unit can be bolted to the monocoque or chassis of a vehicle directly, allowing for “design, engineering and luxury accommodations previously not possible”, while removing the requirement of added subframes or weight.
