Tata Signa 2818.T Price - Specifications & Features

If you’re running a business that needs to move serious cargo between cities — whether that’s industrial goods, FMCG products, construction materials, or bulk freight — the Tata Signa 2818.T is the kind of truck that quietly becomes the backbone of your operations. It’s a 3-axle rigid truck sitting in the 28-tonne GVW category, designed specifically for long-haul transportation, and it comes backed by Tata’s reputation for reliability and one of the widest service networks in India. It’s also available in a CNG variant for operators looking to cut fuel costs on city and intercity routes — more on that below.

Let’s start with the engine, since that’s what you’ll be depending on every single day. The Signa 2818.T is powered by a Cummins ISBe 5.6-litre, 6-cylinder BS-VI diesel engine producing 180 HP and 850 Nm of torque at 1,000–1,600 rpm. In simple terms — 180 HP gives the truck solid highway capability, while 850 Nm of torque is the pulling strength that matters most when the truck is fully loaded and needs to get moving from a stop, climb a bridge, or push through heavy traffic. 850 Nm is a generous figure for this weight class, which means the truck doesn’t feel underpowered even with a full 20-tonne payload on board. The gearbox is a G950 6-speed manual synchromesh unit — six gears is the right spread for a truck doing mixed city and highway work, giving the driver enough range without overcomplicating gear selection on long drives. There’s also an AMT (Automated Manual Transmission) option available, which is essentially a self-shifting gearbox — a genuinely useful feature for drivers who spend a lot of time in city traffic where constant manual gear changes add up to real fatigue by the end of the day. Top speed is 80 km/h, which lines up with standard heavy truck speed limits on Indian highways.

Now, the CNG variant deserves a mention of its own because it’s becoming an increasingly popular choice for operators running regular routes through cities with good CNG infrastructure. The Signa 2818.T CNG uses a 5.7-litre SGI (Sequential Gas Injection) engine producing 180 HP and 650 Nm of torque — slightly lower torque than the diesel version, but the fuel cost savings on CNG can be substantial for operators running high-frequency urban or intercity routes. Mileage on the CNG variant is rated at 4.5–5 kmpl, and it’s available in a single Cowl/5505/32 ft configuration with a 5,505 mm wheelbase.

How big is this truck and how much can it carry? The GVW is 28,000 kg, with a payload capacity of 20,000 kg on the diesel variant and 18,500 kg on the CNG version — a solid carrying capacity that comfortably handles most standard freight loads including containers, packaged goods, and bulk cargo. It’s a 10-tyre, 3-axle truck, and that extra axle and tyre count compared to a standard 6-tyre truck means weight is spread more evenly across the chassis — which helps with stability on loaded highway runs and reduces per-tyre wear over time.

The Signa 2818.T is available in four wheelbase options — 4,880 mm, 5,505 mm, 5,905 mm, and 6,750 mm — giving operators genuine flexibility to choose a body length that matches their cargo type. A shorter 4,880 mm wheelbase suits denser freight that doesn’t need a lot of space, and is easier to manoeuvre in tight loading yards. The longer 6,750 mm wheelbase gives a much bigger loading area, ideal for voluminous cargo like packaged goods, textiles, or light industrial products where the sheer amount of space available per trip matters. Ground clearance is 248 mm — on the higher side, which is genuinely useful for navigating speed breakers, potholes, and the kind of rough approach roads you encounter outside major city limits.

Fuel is always the biggest monthly cost for any truck owner, and the Signa 2818.T does well here. The diesel variant has a 365-litre fuel tank and delivers around 5 kmpl, meaning a single fill can comfortably cover 1,800 km — more than enough for most long-haul corridor runs without a mid-route stop. For an operator running a Kolkata–Patna–Varanasi route regularly, that means one fill at the start and potentially arriving at the destination without needing to stop. The fuel tank size combined with this mileage figure makes the Signa 2818.T a genuinely cost-efficient truck for operators who track running costs carefully.

The cabin is available in both day cab and sleeper configurations, with power steering as standard and a tilt and telescopic steering column that lets the driver adjust the wheel to a comfortable position. The sleeper option is the practical choice for operators doing multi-day routes — a proper rest space in the truck itself means no hotel costs, which adds up significantly over a working month. The truck rides on 295/90R20 radial tube tyres — a widely available size across India, meaning finding replacements on the road is rarely a problem even on remote national highway stretches.

One more thing worth noting — the Tata Signa 2818.T comes with a 6-year or 6,00,000 km warranty, whichever comes first. That’s one of the stronger warranty terms in this segment, and for a business calculating total cost of ownership over a five-year period, it provides meaningful coverage against major drivetrain repair costs during the years when the truck is working hardest.

Pricing for the diesel Signa 2818.T ranges from approximately ₹31.90 lakh to ₹33.75 lakh ex-showroom, with four variants available — CAB 4880, CAB 5505, CAB 5905, and CAB 6750. The CNG variant is priced higher, starting at around ₹39.26 lakh reflecting the additional cost of the CNG fuel system. On-road pricing including registration, insurance, and road tax adds a few more lakhs depending on your state. For businesses looking at a dependable, fuel-efficient 28-tonne truck for regular long-haul work — with the added security of Tata’s wide service network and a strong warranty — the Signa 2818.T is a well-rounded, practical choice that earns its keep every single day.
