Rumour: Tata Motors developing BS6 2.2-litre diesel engine

At present, the Harrier and Safari use a Fiat-sourced 2.0-litre diesel engine.

Tata Motors is said to be working on a BS6-compliant 2.2-litre diesel engine. The updated engine could power the brand’s large SUVs in the future.

Tata’s 2.2-litre diesel engine is said to be equipped with a Lean NOx Trap (LNT) & a Diesel Particulate Filter (DPF) and will require Adblue to meet BS6 emission regulations.

At present, the Harrier and Safari use a Fiat-sourced 2.0-litre diesel engine that makes 168 BHP and 350 Nm. It could be replaced with an in-house 2.2-litre unit, similar to what Mahindra offers in the XUV700.

Tata Motors is also said to be working on a new 1.5-litre turbo-petrol engine. It’s essentially a 1.2-litre turbo-petrol block with a fourth cylinder added to it.
