As the world prepares for real-world emissions testing, a UK company is showing off the equipment and processes for testing vehicles in real time, while they’re doing performing how they’re meant to perform. 

Emissions Analytics recently made an appearance on the BBC motoring magazine program Top Gear to demonstrate its Portable Emissions Testing Systems (PEMS), specifically to demonstrate how different speeds affect fuel consumption.

The test was far from conventional, with the PEMS mounted on a Porsche 718 Cayman for high-speed runs on the show’s test track.

“The Top Gear activity required us to think differently about how we evaluate a car, and we may have unwittingly taken the unofficial record for using PEMS on a test track,” said Nick Molden, founder & CEO of Emissions Analytics. “However, we’re now regularly involved in a hugely diverse range of projects and constantly expanding our experience to cover all aspects of emissions measurement and analysis.”

A specialist in on-road emissions measurement and analysis, Emissions Analytics works in Europe and the U.S. to record standard tailpipe emissions (CO, CO2, NO, NO2 and THCs). Since 2011, the company has tested and analyzed 1,400 passenger models, in addition to heavy trucks, tractors, buses, vans and taxis. The company is also venturing into construction equipment, such as generators as jurisdictions struggle to evaluate the impact small engines have on the environment.

The idea of real world emissions testing came about in the wake of the diesel emissions cheating scandal, where software automatically initiated emissions controls when it detected a vehicle was being tested in a lab — so called “defeat devices” are able to ascertain whether the car was on a dynamometer based on steering wheel angle, barometric pressure and duration of engine operation, among others.
