VM R425 engine in the TX4

Built specifically to meet the latest Euro IV emissions legislation, the VM Motori R 425 DOHC is the cleanest diesel engine ever to beat at the very heart of a LTI taxi. Cleaner and greener with no compromise in economy or power.

Designed by Europe's leading diesel engine specialist specifically for the TX4, the high torque delivery at low speed means you can pull away from a standing start quickly and comfortably, a feature fundamental to taxi operation.

Packs a punch

As you put your foot down, there is no disappointment. The R 425 DOHC effortlessly pulls you up to cruising speed and keeps you there quietly and smoothly as gear driven twin balance shafts within the engine reduce vibration to a minimum.

With four valves per cylinder and common rail multi-stage fuel injection technology it packs a punch never before experienced in a purpose-built taxi.

Working in perfect harmony with the new electronic engine management system, optimum engine performance is achieved as information is seamlessly relayed from the driver to the engine and transmission.

Extensively tested

Finally it is all put to the test. The extensive road and track testing means that you can expect mile after mile of trouble free motoring. The VM Motori R 425 DOHC is the most stringently tested and reliable engine we have ever had.

It's a purpose built engine for the purpose-built taxi.
