With the BSVI emission norms coming into play from April 1, 2020 diesel variants of Tata’s budget models, Tiago and Tigor will be discontinued. The diesel variants of both models draw power from the 1.05-litre, three-cylinder Revotorq oil burner, which cannot be upgraded to meet the BSVI emission norms owing to the high cost involved in calibrating them, resulting in major price bump.
Keeping with the low demand for diesel variants, dropping them from the line-up makes sense for the carmaker.
That said, around 80 per cent of the Tiago & Tigor’s total sales come from their petrol variants that get the 1.2-litre naturally aspirated three-cylinder petrol unit good for maximum power of 85 PS at 6,000 rpm along with peak torque of 114 nm at 3,500 Nm. The 1.2-litre, three-cylinder naturally aspirated engine comes with a five-speed automated manual transmission which is missing in the diesel version.
Set to be axed from April 1, 2020, the diesel variants of Tigor and Tiago feature Tata’s 1.05-litre, three-cylinder Revotorq turbocharged oil burner which makes 70 PS at 4,000 rpm against 140 Nm torque between 1,800 to 3,000 rpm. Only 14 per cent of Tiago’s total sales was drawn by the diesel variants, whereas Tigor diesel accounted for just 15 per cent of the total sales with 114 and 360 units sold respectively during April-January 2019 period.
Launched in 2016, Tata Tiago was the first model from the carmaker to get its contemporary IMPACT design theme. Tigor, on the other hand, is primarily a sedan version of Tiago (subcompact sedan) which derives most of its styling cues from its donor hatchback. The only major difference between the two is the additional boot. While Tiago & Tigor’s diesel variants will be phased out, other carmakers are also looking at discontinuing diesel versions of their small cars.
