True MPG May 2020 – Real-world fuel economy tests

True MPG: Real-world fuel economy tests

Since launching True MPG, What Car? Has tested more than 1000 cars in real-world conditions, using cutting-edge test equipment to establish the real-world fuel economy of new cars. What Car?’s True MPG data has now been used by more than three million visitors to the website since April 2012.

As new models are released and What Car? applies its thorough, real-world True MPG discipline, the vehicle economy rankings shift.

This month, we rank the most efficient SUVs that we’ve tested and compare their results with the official WLTP figures.

1.  Toyota RAV4 Hybrid|  49.0  /  53.5  /  -8.1%

10. Skoda Karoq 1.5 TSI|  44.2  /  40.5  /  -9.1%

The results

The fact that the top-performing SUVs here are hybrids is hardly a surprise, but that one surpasses its official economy figure by almost 16% certainly is.

That result, by the Honda CR-V, is the biggest positive discrepancy of any car we’ve tested so far, and shows that while most cars still won’t match the economy figures printed in sales brochures, some are even more frugal than you might reasonably expect.

At the other end of the scale, the Skoda Karoq misses its official result by the most, recording a True MPG result that’s more than 9% adrift of the official number.
