Published On Mar 17, 2020
The company recently showcased the new BS6 engine family to power the 4-55T range of EUTECH6 trucks. We take a close look.
The biggest change in the new emission regime is essentially the whole powertrain of trucks, and the engine is at the heart of this technological leap. Indian local OEMs have been working relentlessly to get their BS6 trucks ready with contemporary powertrain; now, the trucks are ready to roll-out after several millions of kms of real-life and lap testing. Unlike its peers in the industry, Eicher Truck has an advantage as the company is already manufacturing BS6 engines for the last few years and shipping them to its partner Volvo Truck globally. Now, the company fully prepared with its local BS6 engine family with a brand new truck for the Indian market.
The company recently unveiled BS6 truck range branded as EUTECH6 and the engines family too. It has got a strong 7 engine portfolio inclusive of 5 diesel and 2 CNG ranging between 2-10 litres with power from 100 to 350HP.
Backed by its intense R&D and rigorous testing, Eicher is confident of the performance of these engines in Indian conditions. The company is promising higher torque ranging between 13-30% for its customers as compare to BS4 engines to enable the highest productivity. Eicher believes, this new-gen engine family is adequate to serve the market in a variety of truck combination today and in the near future. However, as per the need of the customers and changing trends, the company can bring any new engine.
VECV has also worked relentlessly over the last year to get its after-sales network in place to support the customers once the BS6 trucks start to spread across the length and breadth of the country.
