Under the rules for the 2014 season, engines must be 1.6-liter V-6 units and incorporate an energy recovery system. One of the toughest regs is the 100-liter fuel limit for each race.
To help boost power and efficiency, turbocharging will be allowed for the first time since the 1988 season. Rev limits are set at a relatively low 15,000 rpm and engines must last at least 4,000 kilometers (2,485 miles) before being replaced. Ferrari explains much of what went into designing the engine and its hybrid system to meet these demands in the video above.
For the energy recovery system, there are two main parts. One electric motor serves as a generator to recover energy from the exhaust while a second electric motor recovers energy during braking. The motor located in the exhaust can also help spool up the turbo while the other motor can also help drive the wheels.
Like the power units from Mercedes AMG and Renault, Ferrari’s new 059/3 is expected to generate around 600 horsepower from the internal combustion engine and an additional 120 kilowatts (161 horsepower) from the electric drive system.
“As a result of the 2014 regulations, we no longer talk of engines, but of power units,” Ferrari’s engine and electronics development boss, Luca Marmorini, said in a statement. “It’s a very complex project and we have been working on it for the past two years.”
