The heart of the Temerario is a twin-turbocharged 4.0-liter V-8 with a hot-vee setup, situating the turbos within the V shape formed by the cylinder banks. On its own, the V-8 delivers 789 horsepower between 9000 and 9750 rpm and pumps out 538 pound-feet of torque between 4000 and 7000 rpm. The eight-cylinder can rev to a lofty 10,000 rpm, and the turbos have a maximum boost pressure of 20.3 psi. The engine features a flat-plane crankshaft and titanium con rods to minimize rotating masses, and Lamborghini says many of the materials used in the engine come from lessons learned in motorsport.
Add in three electric motors, and the Temerario's total output rises to 907 horsepower and 590 pound-feet of torque. Each electric motor emits up to 148 horsepower, with two oil-cooled axial flow motors powering the front axle, giving the Temerario all-wheel drive when needed. Lamborghini says the entire front axle system weighs just 161 pounds, and the front motors can also drive the Temerario in full electric mode. Lamborghini claims its new supercar has 50 percent lower carbon dioxide emissions versus the Huracán. The third electric motor lives between the V-8 and the gearbox and acts as a "torque gap filler" to smooth out gearshifts, eliminate the effects of turbo lag, and improve responsiveness when accelerating from a standstill. This e-motor also operates as a starter motor and three-phase generator.
The juice for the e-motors comes from a 3.8-kWh lithium-ion battery, and by placing the gearbox aft of the engine, Lamborghini was then able to squeeze the battery into the central tunnel to create ideal weight distribution and keep the center of gravity as low as possible. An onboard charger can fully replenish the battery in 30 minutes at up to 7 kW, or the battery can be recharged via the regenerative braking from the front wheels or directly by the combustion engine.
Lamborghini claims that the Temerario will be able to blast from zero to 62 mph in 2.7 seconds en route to a 213-mph top speed. The front-mounted electric motors also allow for precise torque vectoring that should make the Temerario nimbler in tight corners and stabler in high-speed bends. The torque vectoring system relies mainly on the e-motors, intervening with the brakes only when necessary, which Lamborghini says creates more natural driving dynamics. #supercars #lamborghini #temerario #cars #car #CarsTribe
