Engine efficiency was the foundation upon which the Ricardo Group was originally built

Today, we remain pioneers in engine technology with a global reputation for capabilities ranging from design through to manufacture across petroleum, diesel and emerging biofuel and gas engines.


We have a global community of over 800 specialist engineers, providing designs for full engines or individual components. The projects we support range from performance upgrades through to multi-phase design programmes for new high-volume-production engine families.

Fuels, lubricants and aftertreatment

We offer world-class analytical facilities for fuels, lubricants, catalysts and aftertreatment systems. We help clients develop fuels and lubricants for a variety of applications through the optimisation of performance, emissions and fuel consumption. We also provide analysis of catalyst activity to improve aftertreatment systems for all kinds of fuel, including biofuels.

Noise, vibration and harshness (NVH)

We have been a leader in NVH development and optimisation for over 40 years, offering expertise in problem identification and resolution, optimisation and concept design simulation.


From initial design to full turn-key production calibrations, we prepare engines for international markets in full accordance with relevant legislation, with more than 100 different models proceeding to series production. We calibrate engines that use conventional fuels and biofuels, engines for hybrid vehicles, and engines for various other specifications, including turbochargers and exhaust gas recirculation (EGR).

Manufacture and assembly

With an output of up to 2,000 engines per year, our state-of-the-art production facility provides a near clean-room production environment where every process is carried out according to strict quality principles and within a comprehensive ‘no faults forward’ culture.


More than 60 independent test cells operating 24 hours a day across Europe and North America provide rigorous testing of complete engines. Our cells perform tests tailored to the requirements of each client, helping them optimise the performance and durability of an engine throughout its development.

Simulation and analysis

Our software teams develop simulations and analysis specific to each project, from concept layouts through to complete engine design.
