Toyota Hilux 2016 has a Fatal Suspension Problem

Perhaps we should have been more prepared. In 2007 Teknikens Varld tested six pickup trucks. In the moose test the Toyota Hilux ended up as a big failure.

When Ruben Börjesson drove at 57 km/h (35 mph) the vehicle’s left side suspension bottomed out and the right front wheel did a dramatic lift.

Thanks to Ruben Börjesson’s quick reactions he could save the situation and got the car down on all four wheels. The deciding factor was the wide tires that were mounted on the optional bigger wheels which the test car was equipped with.

The grip was too good and in combination with a high center of gravity and the absence of electronic stability control the Toyota Hilux was close to rolling over. After the incident, Toyota throughout Europe halted the sales of Hilux with the bigger wheels.

Now the year is 2016. All pickup trucks in the test have electronic stability control and we do not expect any form of risk or danger.

The systems should when correctly calibrated, manage the avoidance maneuver. The other pickups in the test pass the moose test track at 64-68 km/h (40-42 mph).

When the limit of grip is reached the pickups just understeer straight ahead. But not when the test team enters the new Hilux Toyota.
Oskar Krüger gets behind the wheel and accelerates up to 60 km/h (37 mph). The first attempt is always with low entry speed.

– In the first lane change everything feels fine, says Oskar Krüger.
After that, Oskar steers back to the original lane.
– It feels as if the car gets too much grip.

I am totally focused on getting the car into the first lane again and I notice nothing until we are about to tip over. Then I countersteer and the wheels get back on the ground, says Oskar Krüger.

1. The first attempt and entry speed is 60 km/h (37 mph). A speed that normally doesn’t cause any problems. 2. When the car is about to return to the right lane the left wheel finds grip and the inner wheels lift off the ground. 3. The test driver Oskar Krüger countersteers by routine and gets the car gets back on the ground. 4. The right side of the car is just about to touch the ground again, the danger is over – at least as long as you are driving on an old airfield. 5. Four wheels on the ground, but why did none of the safety systems react? What does the electronic stability control system do?

The moose test is performed with the pickup trucks’ maximum load according to the specifications provided by the manufacturers.

Toyota Hilux has the highest load capacity of the tested pickups, 1 002 kg (2 209 lbs), but in this test it was loaded with only 830 kg (1 830 lbs), including the driver and four passengers, because our weights were not enough. In other words, is not likely that the load is the causing problem here.

If that would be the case the suspension should have bottomed out but it didn’t. Instead, I think the problem lies in the absence of anti-rollover systems and the grip of the tires, says Ruben Börjesson.

Teknikens Värld’s experienced test driver with thousands of moose tests under his collar.
This year’s test car is also equipped with bigger wheels with tires in the dimension 265/60-18. A few days later, we got to test another Hilux with standard 17-inch tires in size 265/65. Once again the Hilux lifts the inside wheel, but less than the other car.

Conclusion
Something is seriously wrong with Toyota’s dynamic safety system, and the result is dependent on the tires the car is equipped with.
