The 2019 Colorado Z71 Trail Runner features underbody protection from the range-topping ZR2 trim, incluidng rocker protection and aluminium skid plates, along with Goodyear Duratrac tyres, automatically locking rear differential, 4.10 axle ratio
, hill-descent control, front off-road recovery tow hooks, and an off-road-oriented suspension.
Quester has a built-in fuel-efficient en- gine and proven driveline which gives the ability to optimize the power out- put, transmission capability and rear axle ratio
. A well specified powertrain ensures that the engine operates at its peak efficiency at all times, enabling good fuel consumption and comfort- able driving experience to the driver.

* AXLE RATIO
: A 3.55 or 3.73 axle ratio
is a better option for all around country living use than the "highway" 3.08,3.23, or 3.31 gearing.
The examples of the issues include the cases with unique vehicle configuration, such as high or very low axle ratio
, and the case when the transmissions down shift during the cruise cycle that causes one of independent variables of the cycle average map, such as average engine speed over vehicle speed, to overlap.
The effect of the parameters in the L18 orthogonal array on 0 to 100 kph time for all engine, step gear automatic transmission and final drive axle ratio
combinations is displayed as the delta time in seconds from the overall mean time as was computed for fuel consumption with Equations 2 through 4.
The new low reduction gears not only improve performance in off-road, heavy haul and construction applications, they enable as well the use of a faster rear axle ratio
to improve on-road fuel economy while maintaining startability.
torque rating, ensuring optimal performance at lower rpm when combined with a 2.26 or 2.28 axle ratio
. The package suits regional applications in flat and hilly road terrains at cruise speeds in the 50 to 62 mph range.
The combination of highly efficient diesel engines, the optimised powertrain, a longer axle ratio
, improved ancillary components, and the BlueEFFICIENCY PLUS efficiency package has reduced fuel consumption to a minimum of 44.4 mpg (NEDC combined).
The vehicle employs new directions to the brand's design language like a generous dash to axle ratio
, low bonnet, sleek silhouette and glass roof.
But armed with a kerb weight 400kgs less than a Bentley 3.0-Litre, a powerful engine and high axle ratio
, the 30-98 became renowned as a high-performance car that could swallow long distances with ease.
All-wheel drive, with a rear:front axle ratio
of 60:40, is standard on all models but can split the power between the axles when necessary.
