Lamborghini has introduced its latest 'baby' supercar, the Temerario, which is already turning heads. Here are some of the most intriguing details revealed at its launch in Monterey.
In electric mode, the Temerario operates as a front-wheel drive vehicle. It combines its 800-hp twin-turbo V-8 engine with three electric motors: one for each front wheel and another integrated between the engine and the eight-speed dual-clutch transmission. The rear motor is directly connected to the crankshaft, ensuring it spins at the same speed as the engine. Without a clutch between the engine and motor, the Temerario defaults to front-wheel drive for all-electric operation.
Lamborghini has not specified the EV range for the Temerario, but with a modest 3.8-kWh battery, it's likely that the V-8 will need to kick in soon. The engine operates at an impressive 36 PSI of boost. Achieving 800 horsepower from a 4.0-liter, eight-cylinder engine required Lamborghini to increase turbo boost pressure significantly, to 36 PSI precisely. The turbos are equipped with speed sensors and electronic wastegates, allowing for precise control of the boost level and operating the turbos near their peak without risk of failure. The three electric motors compensate for any turbo lag during spool-up.
The hybrid system in the Temerario is nearly identical to that of the Revuelto. Both supercars utilize the same axial-flux electric motors, battery pack, and transmission, which is mounted sideways behind the engine. The primary distinction is that the Revuelto's rear motor is mounted atop the transmission and connects to the rear wheels via its own clutch. The Revuelto also lacks a reverse gear, relying solely on electric power for backing up. In contrast, the Temerario features a traditional reverse gear. Additionally, the Revuelto boasts a powerful 6.5-liter naturally aspirated V-12 engine.
The valvetrain of the Temerario is designed to withstand up to 11,000 RPM, despite the V-8's redline being set at 10,000 RPM. This provides a safety margin. Lamborghini opted for roller finger followers instead of hydraulic bucket-and-shim tappets to prevent valve float, a common issue in high-revving engines with conventional valvetrains. This technology is typically found in sport bikes and race cars.
The Temerario is also notable for its increased space, accommodating drivers up to 6 feet 6 inches with a helmet. This marks a departure from Lamborghini's reputation for compact interiors, though LeBron James, at 6 feet 9 inches, might still find it a tight fit.
