Scania G-series

The Scania G series in brief

Scania cabs are designated by letters: P is the lowest, G is mid-height, R is high, and in the new generation, there's also S with flat floors. The G cab is mounted higher than the P, so there's more space inside, and sitting higher gives a better view of the road. At the same time, it's lower and lighter than the R, making it easier to climb into, especially when you have to stop frequently.

Thanks to this compromise, the G series is often chosen for regional haulage, where the driver returns home every few days, as well as for construction, logging, tanker, and crane work. For long-haul trips, where the driver lives in the cab for weeks, the R or S cab is more commonly chosen.

Previous and new generation — what's the difference

The previous generation G series (known as the PGR generation) appeared at the end of the 2000s and was produced until around 2016–2017. It features reliable, simpler electronics, and there are still plenty of these on the used market, although most have high mileage and many engine hours.

The latest generation of Scania was introduced in 2016, with the P and G cabs making their debut around 2017. The cab is more spacious, offers better visibility, improved aerodynamics and safety, and the manufacturer claims lower fuel consumption.

When buying used, you often choose between the latest models of the previous Euro 6 generation and the early models of the new generation of trucks. The new generation is more expensive but more comfortable for the driver and usually more economical.

Engines, gearboxes and axle configurations

In the G series, you'll commonly find 9-litre five-cylinder (around 280–360 hp) and 13-litre six-cylinder (around 370–500 hp) diesel engines. The power is indicated in the name: for example, G 410 means approximately a 410 hp engine. Since 2021, the new generation offers a refreshed 13-litre Super engine, which the manufacturer presents as more economical.

Older trucks are usually Euro 3–Euro 5 class, while from 2013–2014, new trucks registered in Europe are Euro 6. Euro 6 engines require AdBlue fluid and an SCR catalyst, while some Euro 5 engines can operate without AdBlue. It's worth verifying the Euro class in the documents, as it affects road taxes and the ability to enter certain cities' environmental zones.

Most trucks come with the automated Opticruise gearbox, while older models may still have manual ones. Common axle configurations include: 4x2 for regional haulage, 6x2 and 6x4 chassis for heavier loads, 8x4 for tippers, concrete mixers and cranes, and less frequently, all-wheel drive for off-road work.

What to check when buying a used Scania G

Mileage doesn't always show true wear and tear, so ask for a diagnostic report: engine hours, idle time, and average fuel consumption can reveal a lot about how the truck has been used. Mileage and hours should match the service history and tachograph data. Check the tachograph type and calibration date — for international journeys within the EU, a new-generation smart tachograph is required, so an older one might need replacing.

Test the Opticruise gearbox: gears should shift without long pauses or jolts, and the clutch should not slip when moving with a load. If a retarder (hydraulic brake) is fitted, check that it brakes evenly and that there is no oil leakage.

On the chassis, inspect the frame: cracks, weld points, and severe corrosion are particularly common in construction and logging trucks. In Euro 6 vehicles, check the AdBlue system and NOx sensors, ensure that an AdBlue emulator is not installed — it is illegal and can cause issues during technical inspections.

Cab and trim

Scania trucks are custom-ordered, so the equipment varies widely; we list the most commonly found G series versions in Europe.

Scania cab comparison

G cab — a good choice if you need more comfort than a P, but don't need the pricier and heavier R. For regional hauls, a G tractor with a 13-litre engine usually does the trick.
