JLR declined to comment on the report to Automotive News Europe (ANE). Marin Scheidt, head of the motor system at Schaeffler, but told ANE, the latest customer for the system came from the “luxury and sports car segment” and was not a German premium manufacturer.

So far, the system is only under the name Fiat MultiAir in use. Advantages of the system, which allows almost any variation of the valve of an internal combustion engine, according to Schaeffler include improved efficiency and lower CO2 emissions.

However, although the technology learns much popularity among professionals in the last few years, it was not easy to convince customers of the benefits of the whole system, so Scheidt to ANE. Parts of the system are used in BMW’s Valvetronic and Audis AVS systems.

JLR could be a good candidate for the use of the technology as it is currently developing new downsized four-cylinder petrol and diesel engines of type AJ200, will be introduced within the next year, the assessment of IHS Automotive. The technology could help manufacturers to improve fuel efficiency and CO2 footprint of their fleets, especially since it according to the report at an early stage of development come into play and could thus exploit its advantages particularly well.

If this is the case, the system could in all new JLR models that are currently on the way, be applied, as in the new Jaguar XE and the Land Rover Discovery sport. According to the forecast by IHS Automotive Powertrain production number of petrol and diesel variants of the AJ200 engine will reach more than 400,000 units before the end of the decade.
