When it comes to engineering and development of cars, many people think that Elon Musk as the genius of our generation, I feel a little different this is Christian von Koenisegg, and this guy does the impossible. From his fully automatic and manual transmission, to his insane hyper cars, this man knows how to build amazing cars. Now today we will take a deep dive on yet another insane thing build and designed by his company, this is the is the Koenigsegg Gemera and it’s a hybrid 4 seater hypercar, now the electric engines make a 1100HP, but that’s not the part I want to focus on, as it’s a hybrid it also feutures an ice engine. Specifically a little 3 cylinder 2.0 twin turbo engine.
This 2.0-liter twin-turbo three-cylinder powerplant delivers an astonishing 600 horsepower, setting new standards in specific output for road cars. Now this engine is nicknamed the Tiny friendly giant or TFG. Now What makes the TFG even more fascinating is its camless design, employing cutting-edge technology from Koenigsegg's sister company, Freevalve. Let's delve into the engineering and technology behind this remarkable engine and explore how Koenigsegg used this free valve tech, aswell as its genius sequential turbo design to make 600HP out of a 2.0 powerplant.
First lets start by explaining why he chose a small 2.0. you see The TFG was specifically designed for the Gemera, aiming for a compact, lightweight engine with substantial horsepower. Koenigsegg, known for its innovative approach, chose to reverse the power distribution seen in the hybrid Regera, where the internal combustion engine plays a primary role. In the Gemera, most of the power is generated by electric motors, with the TFG contributing propulsion and serving as a charging unit for the hybrid drivetrain's batteries. To fulfill these requirements, Koenigsegg opted for a 2.0-liter, three-cylinder configuration, maximizing power-to-weight ratio while ensuring ample space within the vehicle.
Despite being a three-cylinder engine however, the TFG packs a punch. The engine feutures a bore of 95mm and a stroke of 93.5mm, the TFG exhibits a big-bore, big-stroke design that delivers a distinctive and powerful exhaust note, reminiscent of a Harley with an additional cylinder. Just take a listen. The engine's exceptional valve engineering allows for higher revs, with peak power achieved at 7500 rpm and a redline set at 8500 rpm. Remarkably, this engine doesn’t just produce high end power, the TFG also generates substantial torque, delivering 600nm from below 3000 rpm up to 7000 rpm, ensuring impressive midrange performance.
