Kent’s Un-Limited Motorsport were part of sustainable fuel trial at the latest round of the Kwik Fit British Touring Car Championship at Silverstone.

They ran the extensive trial in a fully competitive environment at the last round, as they look to move to 100% sustainable fuel in the future.

The BTCC has been working closely with long-term partners – Haltermann Carless – on this ground-breaking project, as part of its overall target for all cars entered into the championship to run 100% sustainable fuel.

The last round marked the next milestone of this development when it was agreed that the #18 Duckhams Racing with Un-Limited Motorsport car of Daryl DeLeon would run the latest 100% sustainable fuel for the full duration of the race weekend, with full support provided by Haltermann Carless, TOCA engine supplier M-Sport and Aero Tec Laboratories Ltd (ATL).

DeLeon contested every session with absolutely no fuel issues reported, and critically the pace and performance results were recorded to be equal of those cars running the regular controlled championship fuel.

The #18 Cupra of DeLeon was 13th in Free Practice, lined-up on the grid in the same position, and concluded race day with another 13th place finish. DeLeon and the rookie BTCC squad have only bettered that position on four previous occasions with this result being their 11th overall points finish during an impressive maiden campaign.

Now for the more technical part… Hiperflo ECO102 R100 is a fully sustainable fuel, which meets FIA criteria as an advanced sustainable fuel. 

The fuel is a pure drop-in solution, it requires no hardware modifications to existing engines and crucially delivers no loss in performance compared to the current control fuel used in the championship. The weekend programme proved a huge success, with DeLeon completing all sessions, covering a total of 319km.

The fuel itself achieves a greenhouse gas (GHG) reduction of approximately 55% on a well-to-wheel (WtW) basis compared to the fossil fuel baseline. If the full BTCC grid adopted this fully sustainable fuel for the entire season, it would result in a CO2 reduction of approximately 50,000 kg, equivalent to the combined weight of around 37 BTCC cars.

Series Organiser – TOCA – will continue to work closely alongside Haltermann Carless over the coming weeks and months with the plan to move fully to a 100% sustainable fuel as the championship’s chosen controlled fuel. The DeLeon car is expected to continue running the fuel at the Brands Hatch season finale next weekend (5/6 October).

Haltermann Carless is at the forefront of performance and innovation in motorsport and is celebrating three decades of partnership with the BTCC. Recently, the company was awarded with the highest level of environmental sustainability recognition from the FIA – the FIA 3-star rating.

Alan Gow, BTCC Chief Executive, said: “We are delighted with the significant progress we have made with regard to 100% sustainable fuel – working closely alongside Haltermann Carless and our teams – with last weekend’s results representing a significant milestone in the project.

“The development work doesn’t stop here, however, as we actively strive to even further improve the efficiency and performance of the sustainable fuel going forward.

“This is an important and essential step for the BTCC as we continue to look to maintain the competitiveness and excitement synonymous with our championship, but in a more sustainable way.”
