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.
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 R425 DOHC is the most
stringently tested and reliable engine we have ever had.
It’s a purpose-built engine for the purpose-built taxi.
Automatic Transmission
Proven over 600,000 miles of testing, with 5-speeds and refined for the TX4, the fully
automatic transmission is electronically linked to the entire engine management system.
The carefully chosen ratios match engine output to road speed for the most fuel
efficient use of available power with smooth gear changes.
Manual Transmission
The 5-speed manual transmission is manufactured with increased casing rigidity and the
latest composite construction gearshift technology for improved durability. Like the
automatic, it is refined specifically for the TX4 and delivers greater comfort with
reduced noise which all adds to easier driving.
