Tata Sierra - New vs Old: What's Different?

The new Tata Sierra made a grand debut at the Auto Expo in its near-production Internal Combustion Engine (ICE) form. The modern SUV draws inspiration from the iconic 90s model and is far from just a nostalgic throwback. With over three decades since the original Sierra first hit the roads in 1991, the legendary SUV still holds a special place in Indian automotive history. Here's a head-to-head comparison between the newly revealed Tata Sierra and its legendary predecessor, exploring the evolution of design, technology, and performance. 

Tata Sierra - New vs Old: Design

The new Sierra retains classic elements like the curved rear windows and bold wheel arches while introducing a sharper roofline, a more upright stance, and shorter overhangs. This design approach creates a striking silhouette that's both familiar and distinctly modern.

The old Sierra’s rectangular halogen headlights and grille have undergone a striking transformation in the new model. The updated grille now features a shiny black trim, integrated with connected LED DRLs, the Sierra lettering, and the Tata emblem. The black-finished sleek air intake channels and sharp LED headlights further enhance the look.

The SUV has a contemporary design with vertically-stacked LED fog lamps and a body-coloured bumper featuring a gloss black lower section and a silver skid plate. It replaces the original flap-type handles and two doors with flush-door handles and four doors for enhanced practicality.

The new Sierra features 19-inch alloy wheels wrapped in 195/65 R19 tyres, which gives it a sportier stance compared to the predecessor's thick, high-profile 215/75 R15 tyres. It does not include the roof rails and the extensive black plastic cladding of the original model for a more streamlined appearance. At the rear, the original Sierra’s tailgate-mounted spare wheel and halogen taillights are swapped for a more upright tailgate, integrated LED light bar, roof-mounted spoiler, and a 'Sierra' lettering, giving the new model a refined appearance. 

Tata Sierra - New vs Old: Interior

While there is no official confirmation, the upcoming Sierra is expected to offer a technologically advanced interior, including three 12.3-inch screens, ambient lighting, a four-spoke steering wheel with an illuminated Tata logo, and the option of 4- and 5-seat configurations. In contrast, the original Sierra’s cabin was more basic, with a 5-seat setup, and a folding rear bench. 

Tata Sierra - New vs Old: Powertrain

Following the trend of current Tata cars and SUVs, the new Sierra will likely offer electric, petrol, and diesel powertrain options. The SUV’s ICE version is expected to offer a choice between a 1.5-litre direct-injection turbo-petrol engine (168bhp/250Nm) and a 2.0-litre diesel engine (168bhp/350Nm).

Notably, the old model was initially available with a naturally aspirated diesel engine. However, it later gained a more powerful turbocharged 2.0-litre diesel unit, delivering 89.7bhp and 186Nm. It came standard with a 5-speed manual transmission (standard), and a 4x4 option.
