Tata Signa 4625.S Price - Specifications & Features

The Tata Signa 4625.S is a heavy-duty tractor-trailer, which means it’s the “front unit” — engine, cabin, and chassis — that hooks up to a separate trailer to haul cargo. It’s known for handling tough jobs across industries like logistics, construction, and cargo transportation, offering considerable load-carrying capacity while keeping the driver comfortable on demanding routes. If you’re picturing the kind of truck that pulls a big container or flatbed trailer across highways between cities, that’s exactly the role this one plays.

Let’s start with what’s under the hood. The Signa 4625.S is fitted with a Cummins ISBe 6.7-litre engine producing 250 HP and 950 Nm of torque. In plain terms — horsepower tells you roughly how powerful and fast the truck can be, while torque is the “pulling muscle” that really matters when the truck is fully loaded and needs to get going from a standstill or climb a slope. 950 Nm is a strong number for this segment, so the truck won’t feel like it’s struggling even with a heavy trailer attached. This engine is paired with a Tata G1150, an 8-speed manual gearbox. Eight gears gives the driver a good spread of options — enough to handle slow loading-yard manoeuvres as well as steady highway cruising without constantly hunting for the right gear.

Now, how big is this truck and what can it carry? The GVW (Gross Vehicle Weight) — the truck’s own weight plus everything it’s hauling — is 45,500 kg. Out of that, the payload — meaning how much cargo it can actually carry — is 32,000 kg. It has a wheelbase of 3,320 mm — the wheelbase is the gap between the front and rear wheels, and a shorter one like this makes the truck noticeably easier to manoeuvre in tight loading docks, narrow yards, and busy warehouse areas compared to longer-wheelbase trucks.

Fuel costs are one of the biggest ongoing expenses for any truck owner, so this matters a lot. The Signa 4625.S comes with a 365-litre fuel tank, and gives a mileage of around 3.0 to 4.0 kmpl on both city and highway roads. That number might sound low if you’re used to thinking about car mileage, but for a truck hauling 32 tonnes of cargo, this is a completely normal and even fairly efficient figure — these trucks simply aren’t designed to sip fuel like a car, they’re designed to move serious weight. With a 365-litre tank, the truck can comfortably run for a full day’s worth of highway driving without needing a refuel stop in between, which saves time on long routes.

When it comes to ride comfort and handling rough Indian roads, the Signa 4625.S uses parabolic leaf spring suspension at the front and semi-elliptical multi-leaf spring suspension at the rear. In everyday language — leaf spring suspension is a tried-and-tested system that’s been used in heavy trucks for years because it’s reliable, easy to repair almost anywhere, and does a solid job of soaking up bumps from uneven roads so the cargo and driver don’t get jolted around too much. The truck also comes with an Electronic Stability Control (ESC) system — in simple terms, this is a safety feature that helps the truck stay steady and avoid skidding or losing control, especially useful when the truck is fully loaded and needs to brake suddenly or navigate a sharp turn.

The cabin is built around Tata Motors’ “Power of 6” philosophy, which focuses on performance, fuel efficiency, and ease of use, giving the driver all the space and features needed to stay comfortable and focused on long routes. It comes as a factory-fitted heavy-duty Signa cabin with a sleeper berth, so the driver can rest properly during long trips or while waiting for loading and unloading — and the cabin also comes with AC and ventilation options. It also features a broader windshield and proximity mirrors — basically bigger windows and better-placed mirrors — which means the driver can see more of what’s around the truck, making it safer to drive in busy traffic or tight spaces.

One thing worth highlighting is that businesses can customize the body to suit their specific needs — whether that’s for container movement or aggregate (bulk material like sand or gravel) movement. Since this is a tractor unit, it’s built to be paired with whatever trailer type suits your business — container trailers, flatbeds, tankers, or bulkers — giving operators flexibility depending on what they’re hauling. With 295/90R20 radial tube tyres, the truck uses a tyre size that’s widely available across India, so finding replacements on the road is rarely a problem.

As for pricing, the Tata Signa 4625.S starts at around ₹31.69 lakh ex-showroom in New Delhi, with the CAB variant going up to approximately ₹38.12 lakh depending on configuration. On top of this, you’ll need to budget for registration, insurance, and road tax, which adds a few more lakhs depending on the state. For reference, the monthly EMI works out to roughly ₹61,310 over a 5-year loan tenure at 10.5% interest, with a down payment of around ₹3.17 lakh. For businesses looking at a dependable tractor-trailer for long-haul cargo — with strong torque, decent fuel efficiency, and the backing of Tata’s wide service network across India — the Signa 4625.S is a practical and well-rounded choice in the 45-tonne segment.
