Giga's heavy demand

IN A bid to become the heavy truck heavyweight, Isuzu has launched a new 4x2 Giga model aimed at meeting a demand for prime movers for semi-trailers and cubic B-double combinations.

The EXD 4x2 prime mover is the first of several new models expected to be added to the E Series range in the next year or two. It's the first new model since the Giga was launched in 2000 and the first 4x2 Giga E Series Isuzu has offered.

"We've seen a small growth in reasonably high horsepower 4x2 prime movers in fleets engaged in metro delivery and intrastate delivery," Isuzu product planning and engineering support manager Simon Humphries says.

"We couldn't cover that with our current range of models."

The 41-tonne GCM EXD has a compact 3450mm wheelbase that delivers good articulation in loading bays, a low tare weight, and tapered chassis for easy trailer coupling.

Standard anti-skid brakes, along with EBS electronic braking, boosts the safety and braking performance of the EXD and gives superior balance between the prime mover and trailer brakes.

Isuzu's reliable SiTEC 425 engine provides the grunt with 316kW at 1800 revs and 2059Nm at 1100 revs. A tough-as-nails Eaton Fuller 18-speed transmission delivers the power to the road through a rugged Meritor differential centre and 13-tonne Isuzu rear axle.

A standard rear differential lock provides improved traction.

"The combination of the proven SiTEC 425 engine, rear air suspension, enhanced braking and predominantly American driveline in a compact package will appeal to the market," Humphries says.

Along with all 2006 Giga models, the new EXD is readily identifiable by its revised front bumper and improved fog lamp integration.

It also has a new low-micron, high-flow fuel filter/sedimenter for better protection from dirty fuel.
