The tiny friendly giant engine
The Koenigsegg Gemera´s engine is small. At the same time, it is big when it comes to power, torque and sound. Still, it is small when it comes to emissions and consumption. In short - it is a contradiction of an engine, developed and created by Koenigsegg and its sister company, Freevalve. Therefore, it has been named the “Tiny Friendly Giant” – or TFG for short. Being a two-liter three-cylinder engine, the TFG is future-proofed given its extreme performance, reduced fuel consumption and lowered emissions – not to forget its ability to run on second-generation CO2 neutral renewable fuels.
Koenigsegg direct drive
Koenigsegg Direct Drive (KDD)
Traditional hybrids represent a compromise when it
comes to weight, complexity, cost and packaging.
The Gemera, on the other hand, together with its
sibling the Regera, is a new breed of hybrid. Its
main advantage? Providing ultimate response from
standstill to top speed in the form of a single gear
direct drive at lower weight and higher efficiency
than what any other hybrid solution can offer.
During highway travel, for instance, the KDD reduces drivetrain losses compared to traditional transmissions or CVT by 3-5% as there is no step-up or step-down gear working in series with the final drive – just direct power from the engine to the wheels with the torque-converting HydraCoup locked up.
Torque is crucial, especially when accelerating to extreme speeds in one gear. In the Gemera, this is facilitated by the torque-converting HydraCoup – it converts the combined 1100 Nm coming from the TFG and front e-motor to almost double its torque up to 3000 rpm. That is why the Gemera has 3500 Nm of torque from standstill and why it can accelerate from 0-400 km/h in a single gear.
All-wheel drive, all-wheel torque vectoring, and
all-wheel steering
The separate rear e-motors enable torque
vectoring and reverse. The front axle has an open
differential with a wet clutch pack for each output
shaft, also enabling torque vectoring. This means
that the Gemera has all-wheel drive, all-wheel
torque vectoring, and all-wheel steering, as it also
has independent rear-wheel steering – offering
maximum traction and safety, and one exciting
driving experience. The Gemera also comes with
active ride height to complement driving conditions.
Additionally, the all-wheel torque of over 11000 Nm is clawed into the ground from standstill, creating quite the undertaking for the Gemera’s massive and grippy Michelin Pilot Sport 4S tires.
Combined power output of 1700 bhp
Power output from the three motors – one for each
rear wheel producing 500 bhp and 1000 Nm, and
one E-motor on the crankshaft that produces an
extra 400 bhp and 500 Nm to power the front
wheels – add up to 1400 bhp as individuals and
1100 bhp when combined. In addition to the TFG’s
600 bhp (at 7500 rpm) and torque of 600 Nm
(2000 rpm to 7000 rpm), the combined power
output of the Gemera is 1700 bhp or 1.27 MW.
The 800V battery pack
Taking cues from the Regera, the Gemera’s 800V,
15 kWh battery will provide an amazing 900 kW of
discharge and up to 200 kW of recharge. Every cell
is carefully monitored for voltage, state of charge,
health and temperature; and the cells are enclosed
in a carbon fiber casing for efficiency, safety and
stability. The battery is placed in the most protected
area of the car – under the front seat and in the
carbon-aramid chassis tunnel.
Range
The Gemera can travel up to 50 km in EV only
mode and up to an additional 950 km highway
cruise speed in hybrid mode, before needing a
fill-up – totaling a 1000 km range. This makes the
Gemera a true continent crossing family-oriented
“Autobahn” rocketship.
