Subaru Forester Hybrid: Real-World Test Beats the Sticker Figure by 12%

Australian real-world testing found the new Subaru Forester Hybrid uses 5.5L/100km — 12% less than its official 6.2L/100km claim, with CO2 emissions also below the label figure.

The real-world fuel consumption of the new Subaru Forester Hybrid came in better than its official lab figure — something that's rare for modern cars. In Australian testing, the crossover used 5.5L/100km instead of the claimed 6.2 litres, while CO2 emissions came in at 127g/km against a rated 140g/km. The gap reached 12% and 9% respectively.

The test was run by the Australian Automobile Association (AAA) as part of its Real-World Testing program. Cars are driven on ordinary roads, and the results are compared against the mandatory lab figures shown on every new vehicle's fuel label. The organisation has previously found that 76% of tested petrol, diesel and hybrid models used more fuel than manufacturers claimed.

The Forester now gets a full series-parallel hybrid system in place of the previous mild e-Boxer setup. It pairs a 2.5-litre boxer engine with a drive motor and Subaru's mechanical symmetrical all-wheel drive. Combined output reaches 145kW (197hp), while ground clearance stays at 220mm.

The contrast with the previous generation is stark. The 2023 Forester Hybrid, with its 2.0-litre mild-hybrid system, used 7.4L/100km in the same test — 10% more than claimed, and even more than the petrol Forester's 7.2 litres. The new powertrain isn't just cutting consumption on paper anymore, but on the road too.

With a 63-litre tank, the official range on paper works out to over 1,000km. Going by AAA's 5.5L/100km, that could theoretically stretch to around 1,145km — though that's a rough calculation that ignores fuel reserve, traffic, cold weather and high-speed driving. Subaru itself notes that real-world results depend on driving style, climate, fuel quality and road conditions.

5.5 litres shouldn't be treated as a guaranteed figure. The closest results are likely on a calm, mixed route where the electric motor regularly assists with acceleration and recovers energy under braking. On short cold trips or at highway speeds, the hybrid's advantage will shrink — but the new test confirms that today's Forester is meaningfully more efficient than the old e-Boxer, and not just on a test bench.
