The much-teased Toyota HiLux Tonka concept has been revealed this morning… an adult-sized toy truck.

TOYOTA HAS REVEALED its one-off Toyota HiLux Tonka concept car today ahead of our first drive this afternoon. Designed by the Australian Toyota design team, the drivable adult-sized toy truck celebrates HiLux becoming Australia’s best selling vehicle and coincides with Toyota’s 80th and Tonka’s 70th anniversary.

Clad in yellow and black tiger stripes the Toyota HiLux Tonka concept is a highly modified HiLux that goes well beyond the sandpit duties most Tonka trucks are confined in.

Based on the top spec HiLux SR5 dual cab, the Tonka is powered by a 2.8-litre four-cylinder turbocharged diesel. Ground clearance has increased thanks to the 35-inch tyres, some 75mm or so taller than standard, and Marks 4WD Adaptors portal axles (live rear and independent front) to increase the ground clearance from 225mm to 375mm, and modified suspension at the front. There are also heavy duty springs and adjustable remote reservoir shock absorbers from King springs to deal with the greater unsprung mass.

Approach angle has increased 4 degrees to 35 degrees and departure angle is up 4 degrees to 30 degrees total.

The SR5’s stock 17-inch alloy wheels have been changes for 17 x 8.5-inch Method NV alloys and the original 265/60 rubber replaced with 35 x 12.5-inch Toyo Open Country M/T-R.

A laser cut, TIG welded 6mm alloy bashplate with front overriders protects the HiLux’s guts and side rails protect the body and chassis.

Exterior visual enhancements include a new front bar (compatible with current safety systems) with LED lights and more LED lights in the added roof pod.

Out the back there’s a new tailgate wrapped in carbon fibre with spoiler and air vents, and with strap release instead of a handle. The tub is a removable tubular frame which holds diesel fuel cans, recovery gear and a fire extinguisher.

The whole kit adds 325kg to the HiLux Tonka, which now has a tare weight of 2400kg.

“We have taken Tonka out of the sand pit and reinvented HiLux from top to bottom and from nose to tail,” said Nicolas Hogio, Toyota Australia product design chief.

“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 HiLux Tonka Concept is dramatic evidence that our local team loves to have fun, we’re keen to explore new ideas and we’re always looking to push the boundaries of what’s possible.”

The Tonka will not be going into production, however, adults and kids alike can look forward to experiencing the Tonka at its national tours, 4WD shows, field days and expos.

Practical Motoring is visiting the Toyota HiLux Tonka today and will be reporting back on our ride in the mini monster truck, let us know any questions you might want answered while we’re with it.
