All three remaining engine suppliers to Formula 1 for the 2014 season have now offered a glimpse of their new power units. Ferrari was the last to preview its new 1.6-liter turbo V6 to the media in late December. The team also released a video showing some of the challenges with the new rules and how Ferrari adapted.

Called the 059/3, the engine is supported by a more powerful KERS as Formula 1 stresses energy recovery and efficiency under the new rules that include a 100-liter fuel limit for each race. The teams are also under a fuel-flow regulation of 100 kilograms per hour above 10,500 rpm, and the engine rev limit is set at 15,000 rpm. In addition,teams will be saddled with a 4,000-kilometer duty cycle before engines can be replaced in the car. That’s double the 2,000-kilometer duty cycle in previous seasons.

Teams had been using 2.4-liter V8 engines since 2006, and there were four suppliers: Renault, Mercedes, Ferrari and Cosworth. As predicted by many, the engine parameters are so strict that all three appear very similar in design and probably in output. Veteran F1 observers estimate the engines will produce around 600 horsepower with up to 160 horsepower available from the electric drive. In the past, about 80 horsepower generated by the KERS was available for only six seconds per lap. Now the driver can use twice as much power for 30 seconds per lap.

EngineLabs has already looked at the new Renault engine and considered how the V6 sound will be received. Cosworth will not return to F1 in 2014.
