Tata Motors has marked a significant achievement with its new Hyperion 1.5-litre turbo petrol engine, introduced on the higher-spec variants of the all-new Tata Sierra. During a high-speed test at the NATRAX proving track in Indore, the Sierra equipped with this powertrain clocked an impressive top speed of 222 km/h. This milestone not only makes it the fastest Sierra ever built but also positions it among the quickest SUVs in its segment, underlining Tata's renewed focus on performance and engineering excellence.
The Hyperion 1.5-litre turbo petrol engine comes mated exclusively to a 6-speed automatic transmission and is available only on the Adventure+, Accomplished, and Accomplished+ trims of the new Tata Sierra. Pricing for this powertrain begins at Rs 17.99 lakh, ex-showroom.
Talking about the details of the Tata Sierra, it gets a boxy design inspired by its predecessor but with multiple elements aimed at offering a contemporary appeal. To begin with, the SUV has an upright stance with liberal use of gloss-black panels, which brings together the LED headlights and DRLs with the brand's logo and "Sierra" lettering. All of this is complemented by the presence of a skid plate and two fog lamps integrated into the bumper.
