What do the letters mean?

The type designations of Scania’s 4-series trucks are based on the chassis class concept and other customer-oriented factors. Divided into the L-, D-, C- and G-classes, the 4-series truck range spans applications from high-volume long-distance motorway haulage to gruelling off-road construction work, from city distribution duties to forestry transport on sub-standard roads. GVWs range from around 16 tonnes and up towards 150 tonnes.

Chassis class

Depending on the strength and build-up of the frame and chassis components, Scania 4-series trucks are organised in four chassis classes:

L mostly high-mileage highway operation at gross weights up to 60 tonnes.

D mostly low-mileage urban operation at up to 36 tonnes

C mostly low mileage on- or off-road requiring high ground clearance and good mobility at up to 150 tonnes

G low-to-high mileage haulage on sub-standard roads at up to 150 tonnes 

Chassis adaptation (First A and B in type designation)

Two chassis designs are available:

A-factory-equipped tractor unit

B-basic, mostly intended for rigids 

Wheel configuration

A large number of wheel configurations cover all needs in the heavy segment. The configuration is specified as the number of wheels x number of driven wheels – for certain configurations also including the number of steered wheels:

L-class. 4x2, 6x2, 6x2/4, 6x2*4, 6x4

D-class. 4x2, 6x2, 6x2/4, 6x2*4

C-class. 4x2, 4x4, 6x4, 6x6, 8x4

G-class. 4x2, 6x2, 6x2*4, 6x4, 8x2, 8x4 


6x2/4 six wheels, of which two are driven and four are steered – by means of an additional steered axle ahead of the drive axle (twin-steer)

6x2*4 six wheels, of which two are driven and four are steered – by means of an additional steered axle aft of the drive axle

8x2 a traditional eight-wheeler with two steered front axles, one driven axle and a tag-axle aft of the drive axle

8x4 a traditional eight-wheeler with two steered front axles and tandem bogie 

Chassis height

4-series chassis are available in three relative heights:

H high (C-class)

N normal (all classes)

L low (L- and D-class)

E extra-low (L-class)

Suspension (Second A and B in type designation)

A leaf front, air rear

B air front, air rear – full-air suspension

Z parabolic or multi-leaf springs all-round
