The Horizon Prize for the Engine retrofit for clean air aims at spurring the development of new technologies that can be applied to existing diesel engines and powertrains to reduce pollutant emissions in real driving conditions to a level comparable with that of new cars responding to the emissions legislation in force from 2017.

Priorities and funded actions:

– The Horizon Prize for the Cleanest Engine Retrofit will be awarded to the applicant or team demonstrating the lowest emission of NOX (a generic term for the various nitrogen oxides), PN/PM (particulate matter in terms of number of particles and mass, respectively) and other pollutants under real urban driving conditions on the road as well as under standardized conditions in the laboratory. 

– Safety: must be safe to operate 
– Noise: must comply with applicable noise regulations 
– Total costs of ownership: must not exceed a total of 2000€ over 100.000km 
– Performance and Driveability: must be able to be driven on the prescribed test cycles and not have more than 10% worse acceleration performance than the unmodified donor vehicle (tested in initial testing) from 0-100 and from 80 to 120 km/h and no unacceptable driving behaviours (i.e. response lag and torque discontinuities should not be significantly worse than the donor vehicle)
– Fuel consumption: not worse than 10% with respect to the unmodified donor vehicle
