Dr. Chris Bannister from the University of Bath discusses current trends in vehicle emissions evaluation, emphasizing the importance of real-world driving conditions and advanced testing facilities. The presentation covers European diesel emissions limits, new testing cycles, and ongoing projects aimed at improving vehicle performance and sustainability. The Centre for Low Emissions Vehicle Research (CLEVER) will provide unique testing capabilities in the UK, enhancing collaboration between academia and industry.

European Drive Cycle
• “New European Drive Cycle” or NEDC for short.
• Combination of two older cycles, the “Urban Drive
Cycle” (UDC) and the “Extra Urban Drive Cycle”
(EUDC).

FTP75 Drive Cycle
• One of the US cycles is called the FTP75.
• This was an attempt to build a cycle from “real
world” driving habits.

EU 6.2 Emission Legislation
• Reduced emissions limits
• Inclusion of “real world” driving
– Environmental
– Geographic
– Driver style / behaviour
– Weight
• Details not confirmed – but boundaries are
expected

Centre for Low Emissions
Vehicle Research - CLEVeR
Bridging the gap between the lab and the real world
• This facility combines the ability to replicate on-road, real-
world driving scenarios with the experimental accuracy and
repeatability of the lab environment.
• £2.6M funding from EPSRC
• Facility will be unique within the UK
• Due to open end of Q2 2015
• Available for OEM’s, Universities and SME’s
