The Lotus LMP team will not be present for the opening round of the 2014 World Endurance Championship at Silverstone, it has been confirmed.

The outfit, which steps up to the LMP1 L class (a category within LMP1 for privateer non-Hybrid cars) this season, had been due to run at Silverstone with former F1 driver Christijan Albers, Thomas Holzer and James Rossiter at the wheel.

However, a late change of engine supplier has caused delays for the project, with the decision to work with AER leaving Lotus with no choice but to delay its debut until the second round at Spa in May.

"It was extremely frustrating to be let down by our original engine supplier," said head of operations, Boris Bermes. "We were only notified late December that the supplier of the original engine, a naturally aspirated V8, could not deliver on time.

"We quickly made the decision to work with AER (Advanced Engine Research) with a V6 turbo and we're very happy with the current collaboration. Since the changeover we have worked flat out to ensure that the Lotus LMP car is ready as soon as possible."

"As professional racers, making the decision to miss a race is never taken lightly, there's always a temptation to try and rush the development process just to be out on track. However on this occasion we have decided to be cautious and commit to getting things absolutely right for our shakedown the week after Silverstone ahead of the race in Spa. We have a great team in place and I'm confident that this delay won't hold us back further."

Lotus' exit means Rebellion Racing will go uncontested in the LMP1-L class with its two entries, headed by Nick Heidfeld and Fabio Leimer.
