New GST: Small Cars Become More Affordable; Mix Bag For Hybrids

Updated: Thursday, September 4, 2025, 10:13 [IST]

India's automobile market just got its biggest tax reset in years. The GST Council has slashed rates on small cars, bikes up to 350cc, and three-wheelers to 18% from 28%, effective September 22, 2025. This festive-season reform promises cheaper rides, higher sales, and renewed momentum for the struggling auto sector.

Small Cars, Bikes & Three-Wheelers Get A Tax Break

The biggest winners of the GST overhaul are entry-level vehicles. The council has slashed GST on small cars, bikes up to 350cc, and three-wheelers from 28% to 18%. This is a massive relief for the middle-class buyer, just ahead of the festive season.

Small cars now officially mean petrol cars up to 1200cc or diesel cars up to 1500cc, with a maximum length of 4 metres. This category, which includes popular models like the Maruti Dzire and Kia Syros, falls entirely into the new 18% slab.

Two-wheelers like the Royal Enfield Bullet and Classic 350, along with commuter motorcycles under 350cc, also qualify for this reduced rate. Autorickshaws too get the benefit, making mass mobility more affordable.

Hybrids Get A Mixed Bag

Hybrid cars under 4 metres and within the small car engine limits also join the 18% GST bracket. This makes models like the Nexon CNG, and similar hybrids more affordable.

However, larger hybrids exceeding 1200cc in petrol or 1500cc in diesel, or longer than 4 metres, will be shifted to the higher 40% slab. This includes popular names like the Maruti Grand Vitara, Toyota Innova Hycross, and the new Maruti Victoris hybrid.

Essentially, compact hybrids are incentivised, but full-size hybrid SUVs and sedans will be taxed as luxury or premium models.

What Moves To The 40% Slab?

The GST Council has created a new 40% slab specifically for luxury and high-end vehicles. Earlier, these attracted up to 50% tax including cess, but now they fall under a flat 40% rate without additional cess.

This category includes cars longer than 4 metres with engines above 1200cc (petrol) or 1500cc (diesel), such as the Hyundai Creta, Kia Seltos, Tata Harrier, Mahindra XUV700, and Scorpio N. All of them are set to become slightly cheaper.

Big motorcycles above 350cc, including the KTM Duke 390 and Triumph Speed 400, also fall into this slab. For enthusiasts, that means some relief on high-capacity bikes despite them being labelled "luxury goods."

Commercial Vehicles & Auto Parts Get Uniformity

Buses, trucks, and ambulances now face a flat 18% GST instead of the earlier 28%. This simplification makes commercial mobility more affordable, particularly for state transport and logistics operators.

Auto parts too have been standardised under one 18% slab, cutting through the earlier confusion of multiple HS code-based rates. This will streamline the supply chain and reduce classification disputes.

Manufacturers and suppliers are expected to benefit from this uniformity, ultimately bringing down operational costs in the industry.

Electric Vehicles Stay At 5%

The council has decided to keep GST on EVs unchanged at 5%. This applies to two-wheelers, three-wheelers, and passenger EVs, continuing their status as the most tax-friendly category.

While the rate remains attractive, no clarity has been given on luxury EVs, especially those priced above ₹40 lakh. Brands like Mercedes, BMW, and Tesla may still face uncertainty on taxation.

Nevertheless, for mass-market EVs from Tata and Mahindra, this unchanged rate ensures they remain the most affordable in their respective segments.

Why This Matters For Buyers

The reduction from 28% to 18% translates to real savings. A small hatchback priced at ₹6 lakh ex-factory could now be nearly ₹60,000 cheaper, making cars more accessible to first-time buyers.

For two-wheeler buyers, commuter bikes and scooters will get a much-needed price correction. This is expected to give a strong push to rural and semi-urban demand.

Luxury and premium cars, while still taxed heavily, will also see a slight reduction since the cess has been eliminated. That makes big-ticket purchases somewhat easier.

When Do The New Rates Apply?

All the GST changes come into effect from September 22, 2025-just in time for the festive season rush. Dealers are already expecting demand to surge as customers hold off purchases until the new slabs apply.

DriveSpark Thinks

This timing of GST reform is crucial as the auto industry has been struggling with weak sales. A pre-festival tax cut could be the booster shot the sector needs.

For buyers, this reform means the festive season will not just bring discounts but also genuine tax savings, making vehicles across segments more affordable than before.
