Ashok Leyland 5532 AN (A6) LNG 6×4 is the brand’s first flexi-fuel truck that can switch between LNG (Liquified natural gas) and CNG (Compressed natural gas) fuel options based on availability.

At the on-going Auto Expo 2023 in Greater Noida, Ashok Leyland has unveiled an innovative natural-gas powered truck with dual-fuel option. The A6 LNG 6×4 tractor also boasts a refreshed ‘Premium N’ cab design that looks both futuristic and premium, debuting for the first time.

The LNG truck is powered by A-series 6-cylinder natural-gas engine that mimics a spark-ignited petrol engine, unlike compression-technology based diesel engines. The engine is mated to a 9-speed synchromesh gearbox with a crawler gear and 430 mm clutch with air-assisted hydraulic booster.

The A6 LNG truck generates 240 kW of max power at 2,200 rpm and 1,200 Nm of torque at 1,200 – 1,800 rpm. It sits on modular and heavy-duty AVTR platform featuring HSS frame and robust chassis design, which can be configured for a wide-range of variant requirements. Wheel base of the LNG truck is 3,900 mm.

But the interesting aspect of this truck is the on-board intelligent flexi-fuel systems that can automatically switch from LNG to CNG and vice-versa depending on the fuel availability in their respective tanks. The truck is equipped with a 990 litre LNG cryogenic tank, along with four CNG tanks of 40 litre capacity.

While the LNG is stored in liquid form at cryogenic temperatures, the fuel represents more energy (in terms of calorific value per volume) than CNG, this making it ideal for long-haul transportation. The additional option of CNG eases the range anxiety associated with LNG, as CNG stations are far more common and can be a handy fuel option in city areas.

Further, the A6 LNG truck debuts Ashok Leyland’s next-generation ‘Premium N‘ cab design. The restyled cabin features sleek-looking LED multi-beam headlamps with elongated DRLs, redesigned dashboard and steering, tiltable telescopic steering, new instrumentation cluster and suspended driver seat.
