Toyota HiLux Tonka Concept Unboxed – Australian Dream Truck is a Serious Off-Roader

By Steve & Tamami Laser

Toyota Australia tugs at our heartstrings with a new concept truck designed for kids of all ages (especially big kids). The HiLux Tonka Concept that blends the reputations for toughness of both brands is a high-riding off-roader that loves to play in the dirt.

Based on an Australian market Toyota HiLux 4×4 Double-Cab SR5 with a 2.8-liter 4-cylinder turbodiesel engine, the concept was conceived, assembled and tested by designers and engineers from Toyota Australia’s product planning and development division.

Product design chief Nicolas Hogios said the extreme style and capability of the HiLux Tonka Concept would capture the imagination of kids and adults alike.

“We have taken Tonka out of the sand pit and reinvented HiLux from top to bottom and from nose to tail,” he said. “Inspired by the Tonka trucks that kids play with in their backyards, the HiLux Tonka Concept goes way beyond the already hugely capable abilities of HiLux to traverse rocks and other rugged terrain.”

The extreme makeover begins with an increase in ride height of 150mm (6 inches). Combined with a high-riding axle, heavy-duty suspension and 35-inch diameter tires, Toyota says the HiLux Tonka Concept is equipped to power over rugged terrain.

A new front bar is “compatible with the vehicle’s safety systems” while the hood has a carbon-fiber skin and features an aggressive “power bulge” and air scoops.

High-performance off-road LED lighting in the bar and roof pod combine to enhance nighttime vision on off-road trails. A rugged bash plate made from 6mm-thick alloy protects the sump and other components while tubular side rails help guard the body and chassis.

The development team changed nearly everything behind the cabin. The transformation includes a new tailgate, also wrapped in carbon fiber, that incorporates an integrated spoiler and two air vents. A lightweight strap releases the tailgate.

Inside the bed, a removeable tubular frame keeps gear in place, including diesel fuel cans, while storage boxes house recovery gear for extreme off-roading. A fire extinguisher, axe, shovel and high-lift jack are also fitted.

Tonka is a household name, celebrating its 70th anniversary this year. Toyota Australia says that since HiLux was first launched in 1968 it has earned and reinforced its reputation for being “unbreakable” and for being quite popular.

Through the end of February this year, Toyota says Australians have bought more than 920,000 examples including 530,000 4x4s and 390,000 4x2s while globally, HiLux sales have topped 16 million.

Toyota Australia’s product design and engineering capabilities have global reach, supporting the development of vehicles manufactured for Australia, the Asia-Pacific region and other markets.

While the HiLux Tonka Concept is not destined for dealer showrooms, adults and kids alike will have the opportunity to share the dream as it tours 4WD shows, field days and expos around Australia.

Here’s a key spec comparison between the concept and a production vehicle followed by a summary of mods:
