Service Training BT-50


General Information
General Information
Product Concept
•

The new Mazda BT-50 supersedes the B-Series, Mazda’s present pick-up truck. The
aim of the BT-50 development team was to create a new pickup model in line with the
current model range delivering Mazda’s Zoom-Zoom spirit in its individual and distinctive
way.

•

The BT-50 has inherited the tough and reliable commercial truck performance of the BSeries. Simultaneously it presents a new fresh body styling and technologies that
customers enjoy on passenger cars and also demand more and more for pick-up trucks.

•

The BT-50 is offered with RWD (Rear Wheel Drive) layout as 2WD or as manually
activated part-time 4WD.

BT-50_00001

Service Training BT-50

00-1


General Information
•

Plane body panels without the formerly used swage lines and other new styling elements
contribute to a more brawny, but clear and modern overall styling impression.

BT-50_00002

BT-50_00022

00-2

Service Training BT-50

General Information
•

The design and material quality of the interior has been improved and now reminds more
of a passenger car than of a pick-up truck.

BT-50_00003

•

Beside the clearly arranged instrument panel the completely new T-shaped dashboard
contains a centre stack panel incorporating the latest modular audio system and the
climate control panel, both with easy to operate control elements.

BT-50_00004

Service Training BT-50

00-3


General Information
•

New features of the powertrain, such as the 16-valve DOHC-diesel engine with common
rail direct injection and Euro 4 emission standard, the dual-mass flywheel or the 5-speed
transmission S15M(X)-D contribute to a driving performance and emission output that
are comparable to passenger cars.

•

The noise level emitted by the engine has been significantly reduced by the common rail
injection system and additionally dampened by broad use of insulation materials.

BT-50_00005

00-4

Service Training BT-50


General Information
•

Other well-proven components, which are adopted from the B-Series as e.g. the chassis
with the ladder frame and the suspension, are refined by major or minor changes in
material, form, and/or dimension.

BT-50_00006

•

The supplemental restraint system is now enhanced by combined head / side airbags as
used on the MX-5 (NC).

*2: If the vehicle is operated primarily under any of the following conditions, replace
the engine oil and oil filter more often than the recommended intervals.

a) Driving in dusty conditions
b) Extended periods of idling or low speed driving
c) Driving for long periods in cold temperatures or driving regularly at short
distance (less than 8 km/ 5 miles) only

7: If the vehicle is operated primarily under any of the following conditions, inspect
the disc brakes and drum brakes more often than the recommended intervals.
a) Driving on bumpy roads, gravel roads, snowy roads or unpaved roads
b) Driving uphill and downhill frequently
c) Repeated short-distance driving

–

*

8: If the vehicle is operated primarily under any of the following conditions, replace

WL-C Engine

WL-C Engine
•

The BT-50 is offered with the 2.5 L common rail diesel engine, which has the
identification code WL-C.

•

The design and operation of the WL-C engine are essentially carried over from that of
the B-Series with WLT-3 engine, except for the new features described in the respective
sections.

NOTE: Further information can be found in the Training Manual of the ‘B-Series’ (NMT-005)
