The 2014 Formula 1 season will be defined by the introduction of advanced new hybrid engines. These new power units are built around a 1600cc turbocharged V6 with direct fuel injection. But that really only the tip of a very big and complex iceberg.

The engines have a double restriction on fuel consumption which will really change everything. In 2014 they will have cover a grand prix distance using 35% less fuel, with a maximum fuel load of 100kg (not the same as 100 litres). On top of that the rate of fuel flow is also limited to 100kg/hour. Now it does not take a scientist to work out that at the maximum flow rate the cars could not finish the race. So other strategies must be employed. This is where the ‘double hybrid’ system comes in.

The power units are fitted with two electric motors, one linked directly to the turbocharger, the other working in the same was that KERS MGU’s have done in the past. The combined maximum power output will be around 760bhp similar to the output of the rev limited V8’s of 2013.

But the make up of these power units is both complex and fascinating.
