Lotus gets go-ahead for engine upgrades

The IndyCar Series has approved Lotus' request to make improvements to their engine, to make up for the unit's power deficiency compared with rivals Honda and Chevrolet.
The IZOD IndyCar Series announced on Thursday that it had given the go-ahead to Lotus to introduce a series of upgrades to its engine design in order to allow it to catch up with rival manufacturers Honda and Chevrolet.

"Now that the IndyCar Series has giving us permission to improve the engine performance, things will be moving soon," said Olivier Picquenot, Lotus' IndyCar program manager. "The purpose is to get some outside help to assist in the new development plan for the Lotus engine. Everyone has been working well together and looking to make some quick progress in a concrete way."

The approval came under an existing provision in the series rulebook which allows the engine suppliers to petition for the chance to change their engine specification even though the units are meant to be frozen through to the end of the 2016 season.

Rule 4.7 states: "At June 18 and again at the end of the year manufacturers whose engines are statistically more than 2.5 per cent deficient in power may, at the sole discretion and evaluation of IndyCar, make improvements to be homologated immediately."

Lotus duly lodged the paperwork on the stated date, supplying data from testing, practice and race sessions proving that the engine was more than 2.5 per cent down on power. There was little problem demonstrating this, with Lotus' cars painfully down on speed on the ovals and even getting parked ten laps into the Indianapolis 500 for being unable to run within 105 per cent of the leaders' times.

Two IndyCar teams - Bryan Herta Autosport and Dreyer & Reinbold Racing - started the year with Lotus engines but negotiated their way out of their contracts when the power shortfall became apparent. A third team, Dragon Racing, split in more acrimonious circumstances in the weeks building up to the Indy 500 in May, after filing a lawsuit against Lotus.

The June 18 homologation waiver application laid out the requested series of changes to be phased in, which will start with a test on July 2 at Mid-Ohio Sports Car Course with the HVM Racing car of Simona de Silvestro, the only driver now using Lotus power full time in the series. The rules are clear that the proposed solution cannot simply be through allowing more turbocharge boost or turning up the RPM, but has to come from design-led improvements to the engine itself.

“The intention of the rules is that you can't just go and request more boost or revs," agreed John Judd Jr. of the family-run UK-based Engine Developments Limited company that is contracted to design and build the Lotus engines. "You give them a shopping list of items you'd like to change, but wouldn't be allowed to under the existing homologation regulations."

Judd pointed out that changes to the camshaft profile were just one thing not allowed under the formal rules that they wanted to be able to introduce under this mid-year dispensation.

I hope this allows Lotus to get competitive. I'd love to see a three way fight for the balance of the season, and Lotus add more teams next year.

I do hope this restores some level of parity, I feel so sorry for Simona de Silvestro who was showing some promise at the start of last year. This year's car is so far off the pace it's impossible to judge. Can't see Nissan moving into Indycars, they had a very big presence at Le Mans with the Deltawing and several LMP-2 cars. I could see a full factory move there, or possibly a racing version of the GT-R for customers
