Bringing out their second-generation IMV or Innovative Multipurpose Vehicle to its first long-distance road trip at the annual Toyota Road Trek, Toyota Motor Philippines took the opportunity to test the real-world fuel mileage provided by the new GD-series diesel and Dual VVT-i equipped TR-series gasoline engines.
Using their own product planners and marketing executives as guinea pigs, they set a route from Toyota Puerto Princesa to Astoria Palawan resort some 53 kilometers away. With a load of four passengers and with the climate control set at maximum blower and lowest temperature, they set the following benchmarks after four trips:
Then, they told the media to beat these results, only relaxing the rule on air conditioning (but most kept them on since the drive took place midday). Toyota even put in weight ballasts for teams who were composed of only three members.
Driving on unfamiliar roads, they set a 60-minute limit to get from Toyota Puerto Princesa to Astoria Palawan.
These are the results:
Comparing the results with Toyota’s benchmark, it’s clear that the media could coax out more mileage per drop of fuel (in terms of percentage) when the GD-series engine is mated to an automatic transmission. The Top 5 (a mix of Hilux, Fortuner, and Innova) are all equipped with Toyota’s new 6-speed automatic. It must be noted though that Toyota’s product planners could get more with the manual transmission models perhaps because they went through the same course repeatedly, and familiarity with the terrain helps a lot during fuel economy runs.
Of course, this real-world test presents an interesting fact to would-be Toyota buyers. Unless you know a particular terrain/location by heart, getting your new Fortuner, Hilux, or Innova with an automatic gearbox is a surefire way to get the most out of every drop of fuel.
