2026 Mazda BT-50 gets more frugal new diesel engine option for a higher price

Date:

The 2026 Mazda BT-50 is now available with new 2.2-litre four-cylinder turbo-diesel engine to replace the previous entry-level 1.9-litre engine, bringing higher outputs, lower fuel consumption, and a 3500kg braked towing capacity across the range, but a $1500 price increase.

Available only in the entry-level XS equipment grade starting with the 4×2 single-cab/chassis variant priced at $37,900 before on-road costs, it produces 120kW of power and 400Nm of torque – gains of 10kW and 50Nm over the 1.9-litre four-cylinder turbo-diesel it replaces. 

While peak power arrives at the same 3600rpm, the higher torque output peaks from 1600 to 2400rpm compared to the 1.9L engine’s 1800-2600rpm spread.

The same engine, codenamed RZ4F-TC, will also be available from October in the Isuzu D-Max, with which the BT-50 is twinned and produced alongside in Thailand, with the two utes using the same platform and engines.

In the Mazda, it’s offered exclusively in four variants: the entry-level XS Single Cab Chassis 4×2, the XS Dual Cab Pickup 4×2, the XS Dual Cab Chassis 4×2 and the XS Dual Cab Pickup 4×4.

All four model grades command the same $1500 price premium over their 1.9L-engined predecessors, but also cost more than equivalent variants of the D-Max, which starts at $36,200 before on-roads or $36,990 drive-away.

The new 2.2L turbo-diesel is teamed with an eight-speed automatic as standard (unlike the D-Max, the BT-50 was already a manual-only model), while the more powerful 3.0-litre four-cylinder turbo-diesel in higher-grade BT-50s continues with a six-speed automatic.

The new 2.2L engine also comes with an engine idle stop/start system as standard to lower fuel use and CO2 emissions by up to 0.7L/100km and 17g/km respectively, with the most efficient BT-50 XS dual-cab pickup variant now offering a combined fuel consumption figure of 6.3L/100km and CO2 emissions of 167gkm – down from 7.0L/100km and 184g/km.
