Ultimate Cell Trial on Mercedes BTCC Logistics Truck: Verified Efficiency & Emissions Reduction

Ultimate Cell® partnered with BTCC driver Árón Taylor-Smith to test the performance of our “hydrogen-on-demand” technology on the team’s Mercedes race support truck. After gathering several weeks of baseline fuel-consumption data, the truck was fitted with two Triple Ultimate Cell® units and monitored across five race-weekend journeys.

This case study demonstrates the significant value Ultimate Cell® can bring to motorsport logistics fleets, transport operators, and organisations seeking measurable sustainability impact.

CASE STUDY REPORT:

Assessing the impact of ULTIMATE CELL®“Hydrogen-on-Demand” Technology on a Mercedes Logistics Truck – WL64 HBL with Árón Taylor-Smith Racing (BTCC)

Trial Overview

In the 2025 BTCC season, Ultimate Cell UK Ltd partnered with professional racing driver Árón Taylor-Smith to test the impact of hydrogen-on-demand technology on the team’s Mercedes logistics support truck (WL64 HBL). This heavy-duty vehicle transports race cars, equipment, and pitwall infrastructure across all UK rounds of the championship.

After collecting several weeks of baseline, performance data, two Triple Ultimate Cell®,units (six cells in total) were installed on 23 May 2025, allowing a direct comparison between pre-install and post-install fuel performance during real-world race logistics.

Key Outcomes

33% Improvement in Fuel Efficiency

Across all journeys following installation:

• Miles per litre increased from 1.61 → 2.10
• MPG increased from 7.31 → 9.54 MPG
• Equivalent to a +33.8% improvement in overall efficiency
• These results remained consistent across varying terrains, distances, and payloads typical of BTCC operations.

Fuel Consumption Pre-Install

Baseline Fuel Consumption (Pre-Install)

Average MPG: 7.31 mpg
Average Miles per Litre: 1.61 mpl

Fuel Consumption Post-Install

Post-Installation Fuel Consumption (Ultimate Cell Fitted)

Average MPG: 9.54 mpg
Average Miles per Litre: 2.10 mpl

Environmental and Savings Impact

Fuel Savings

• A 33% improvement in miles per litre results in a substantial seasonal reduction in fuel used.

Estimated Seasonal Fuel Saving

• Assuming a ~4,000-mile BTCC logistics season:
• Baseline efficiency: 1.61 mpl → 2,484 litres required
• Post-install efficiency: 2.10 mpl → 1,905 litres required
• Fuel saved: 579 litres with up to £869 per season
  (Fuel cost saving based on £1.50/litre)

CO2 Reduction

• Every litre of diesel saved avoids 2.68 kg CO2.
• 579 litres saved × 2.68 kg = 1,551 kg CO2 avoided
• Approx. ≈ 1.55 tonnes CO2 saved per season

Driver & Team Feedback

Árón and the team reported:

• Noticeably stronger torque on long
  gradients
• Smoother acceleration and reduced
  gear hunting
• Quieter, more stable engine behaviour
• No adverse mechanical effects
• Zero downtime required

Summary

CONCLUSION

The Ultimate Cell® system delivered:

• 33% improvement in operational fuel efficiency
• Lower fuel costs
• Reduced emissions
• Noticeable improvements in torque, driveability and engine smoothness
• Zero modifications to the Mercedes engine
• Real-world validation within a demanding motorsport logistics environment

The partnership with Árón Taylor-Smith Racing demonstrates the performance-enhancing, cost-saving, and sustainability benefits Ultimate Cell®brings to logistics vehicles.

NOTE:

• This ROI reflects motorsport logistics, where mileage is relatively low. In commercial transport environments (30,000–70,000 miles/year),
• ROI is typically 6–12 months, which is why Ultimate Cell® is primarily deployed in plant, HGV, municipal fleets and logistics operators.
• This case study demonstrates performance, emissions reduction, and real-world efficiency, rather than high-mileage ROI.
