The article also explains that in 2013 LMP2 engines must last longer between rebuilds.

An extract from the LMP 2012 technical regulations

5.6 LMP2 homologated engine
5.6.1 Type
The engine must be made in a minimum of 1000 units in 12 consecutive months and come :
- Either from a grand touring car,
- Or from a large production car.
It is made reliable for competition use and developed to reach the output target of 450 hp without exceeding the price below:
If the engine is sold:

• Purchase price: € 75 000 maximum
• Rebuilt price: € 35 000 maximum
• Engine life between 2 rebuilds:
  Target: 2011: 30 h, 2013: 50h

If the engine is leased:
The hourly operating cost must be:

• €1650 in 2011 and 2012 (30 h between 2 rebuilds)
• €1150 in 2013 (50 h between 2 rebuilds)

Judd is not happy with that requirement:

There are concerns among the manufacturers, particularly Nissan and ourselves, regarding the life of the standard parts. We have got standard parts that don't do enough miles. It is absolutely stupid to make a regulation that says that you cannot use a racing engine. You have to use an engine that is made for something else. It is like saying that you have to use a washing machine as a fridge.

We could do a cheaper and a better job with a racing engine. All the major components with that will do 20,000 km, but we have parts now that won't do 8,000 km! In 2010 we were supplying DBs to race performance at a bit below the cost cap for the following year, but it was interesting to see that after 35 years, Formula 3 engines are not production based. You have a million production-based four cylinder engines, but the FIA have allowed race engines instead. It is heavily cost capped, but you can do a racing engine.
