Which SUV is Better? Isuzu MU-X vs Toyota Fortuner Head-to-Head Review

In a detailed comparison between the flagship variants of the Isuzu MU-X and the Toyota Fortuner, David Taylor highlights the key differences and similarities between the 7-seat, bakkie-based Adventure SUVs, offering insights for potential buyers.

The Toyota Fortuner is a household name and has dominated the 7-seat, bakkie-based Adventure SUV market since the 1st-gen model was launched in 2006. But now that the 2nd-gen model is in the twilight of its product life, who does it compare with the recently updated Isuzu MU-X, of which the 2nd-gen arrived in South Africa in 2021? The combatants in this head-to-head comparison are the Isuzu MU-X 3.0TD Onyx XT 4WD and Toyota Fortuner 2.8GD-6 4×4 GR-Sport, both of which top their line-ups.

MU-X vs Fortuner: Performance & Efficiency

The Isuzu MU-X Onyx is powered by a 3.0-litre 4-cylinder turbodiesel engine that produces 140 kW and 450 Nm of torque, which is mated with a 6-speed automatic transmission.

When we tested the Isuzu’s 0-100 kph time, it hit the benchmark in 10.61 seconds; in terms of in-gear acceleration, it feels a little “lumbering”, even if its transmission shifts admirably smoothly.

Isuzu claims an average consumption of 7.6 L/100 km, but the MU-X averaged 8.6 L/100 km during its tenure in our fleet. Both models have an 80-litre fuel tank, providing a good range for extended journeys.

The Toyota Fortuner GR-Sport has a 2.8-litre 4-cylinder turbodiesel engine that generates 165 kW and 550 Nm of torque in the range’s flagship variant. This also uses a 6-speed automatic transmission, and according to our test equipment, the more muscular Fortuner hit 100 kph from zero in 9.22 seconds.

The Fortuner also has 3 drive modes to choose from – Eco, Normal, and Sport – which the Isuzu lacks, adding to its energetic feel. The Fortuner’s motor simply feels more modern and refined. Toyota claims an average fuel consumption of 8.4 L/100 km, though the test vehicle averaged just over 10 L/100 km.

What are the Isuzu and Toyota like to drive off-road?

Most people buy these models as family vehicles because they want to be able to drive anywhere, even if only occasionally. Because the Isuzu MU-X and Toyota Fortuner are built on a ladder-frame chassis, a design that prioritises off-road articulation over on-road comfort, they’re very capable off-road.

Both vehicles are very closely matched in terms of their 4×4 systems, with both having low range and a differential lock. However, a major difference lies in the tyres. The Fortuner GR-Sport comes standard with all-terrain tyres, which are a significant advantage for off-road use. In contrast, the Isuzu MU-X is sold with low-profile tyres, which look quite sporty, but are not as suitable for serious off-roading.

MU-X vs Fortuner: Interior Features

The Isuzu MU-X Onyx facelift brings significant improvements to the cabin. A new, higher-resolution infotainment screen is a notable update, which includes graphics and a digital instrument cluster. The build quality is good with some soft-touch plastics and attractive contrast stitching on the panels.

However, some negatives include the glossy plastic on the centre console that is bound to be scratched easily and a slight movement in the door when the window is opened. The MU-X offers standard features like heated seats, wireless Android Auto, and a partly digital instrument cluster.

To distinguish the Toyota Fortuner GR Sport’s interior from those of its siblings, it features a handful of aesthetic touches, including red stitching and sporty seats. However, the cabin feels dated, especially the infotainment system, which is described as “old school” and “antiquated” compared to rivals.

The reverse-view camera is singled out for its particularly poor, low-resolution quality. While the Fortuner has an impressive JBL audio system, the MU-X has a slight, but notable advantage in terms of standard features, including wireless phone connectivity, while the Fortuner requires a cable.

MU-X vs Fortuner: Practicality & Space

The 2nd-row seating in both Adventure SUVs is a key differentiator. In the Toyota Fortuner, knee room is good, but headroom is a bit tight. The GR-Sport’s 2nd row features USB-C ports, shopping bag hooks, a 220V inverter for charging laptops and roof-mounted ventilation outlets. However, its seating position feels too elevated, and the seatbacks’ reclining function is limited because of the 3rd-row configuration.

The Isuzu MU-X‘s 2nd row is praised for feeling more spacious and having a more natural seating position. It offers better headroom and a more generous recline function. Like the Fortuner, it has a shopping bag holder, 2 illuminated USB-C charging ports, and (circular) roof-mounted ventilation outlets.

In terms of comfort and convenience, the Isuzu offers a better 2nd-row experience than the Toyota.

When it comes to the load bay, both vehicles have a powered tailgate. The Isuzu MU-X is favoured for its logical storage of the 3rd-row seats, which fold flat into the floor, creating a large, flat loading space.

The Toyota Fortuner‘s 3rd-row seats, however, stow by folding up and to the sides, which impinges on the available luggage capacity (width-wise, anyway), which may (continue to) frustrate some consumers. While the Fortuner’s load floor is slightly deeper, the overall functionality of the MU-X’s bay is broader.

Price & after-sales Support

In terms of after-sales support, the Toyota Fortuner comes with a 3-year/100 000 km warranty, while the Isuzu MU-X has a longer 5-year/120 000 km warranty. Their service plans are comparable, with the MU-X offered with a 5-year/90 000 km plan and the Fortuner a 9 services/90 000 km plan. Both of these models are renowned for reliability, and Toyota is a 5-time Cars.co.za Awards Brand of the Year winner.

Summary: Isuzu MU-X vs Toyota Fortuner

The comparison between the 7-seat Adventure SUVs is not one-sided, as both have their merits. Despite being an older product, the Toyota Fortuner maintains its relevance with a more powerful and refined engine, better in-gear performance, and standard all-terrain tyres, which improve its off-road capability. Its cabin is dated, but it has high-quality touches and feels robust. It’s not a market leader by accident.

The newer Isuzu MU-X, with its recent facelift, brings a welcome sense of modernity to the segment, particularly in its interior. It has a more practical and comfortable 2nd-row seating arrangement and a more logical load bay design with flat-folding 3rd-row seats. Its infotainment system is more up-to-date and offers wireless phone connectivity, while its longer warranty provides peace of mind for buyers.

While both models impress, the final choice depends on whether a buyer prioritises performance and serious off-road readiness or modern comfort, practicality, and a 2-year longer manufacturer warranty.
