HILUX AND FORTUNER GAIN 48V TECHNOLOGY

Available immediately, the best-selling eighth-generation Hilux and segment-de ning new Fortuner SUV are available in South Africa with the choice of 48V mild-hybrid technology mated with the brand’s venerable 2.8 GD-6 turbodiesel powertrain and six-speed automatic transmission.

Seamlessly integrated within this proven powertrain, the advantage of this compact and lightweight technology is that it offers greater ef ciency, improved driving performance and enhanced comfort in both urban and off-road environments.

Capable of delivering up to 12 kw and 65 N.m of additional power and torque to the vehicle’s powertrain, this 48V motor/generator replaces a conventional alternator within the engine’s packaging. Powered by a battery housed below the rear passenger seat, this system also incorporates a DC-DC converter to supplement the workings of the vehicle’s other 12V componentry, thus improving overall ef ciency.

By lowering the GD-6’S idle speed from 720 to just 600 r/min, the 48V system aims to improve average fuel consumption by working in conjunction with an advanced start/stop system. In an urban environment, this setup works seamlessly – and is mated via a twoarm belt tensioner – to re the engine back to life the instant the brake pedal is lifted. Initial pull-away is also made that much more controlled via this electric supplement.

The 48V battery weighs just 7.6 kilograms and is recharged on the move via energy harnessed from the regenerative braking system.

Of course, both Hilux and Fortuner are known for their rugged, adventure-focused character, including the former’s formidable reputation as a rugged workhorse. While the 48V motor itself is mated to the GD-6 motor via a two-arm belt tensioner and highstrength rib side fabric belt to help ensure durability with improved slip resistance in wet conditions, all other associated componentry is speci cally packaged to complement these two tough contenders. This includes retaining the stated wading depth of any of the respective packages in which it’s installed.
