The most attentive readers of our weekly column of the proof of real consumption they will certainly have noticed that the just tested Toyota Yaris Cross Hybrid she managed to cover the 360 km standard route from Rome to Forlì consuming a little less than her younger sister Yaris Hybrid.
This may have surprised many, especially considering the fact that the Yaris Cross is bigger, taller and probably heavier than the Yaris. Aerodynamics also seem to be unfavorable to the raised crossover version, but the nearly identical consumption results between the two deserve an explanation and a comparison that we try to do together with you.
Yaris Cross and Yaris, practically on par
First of all, it must be said that the difference between the consumption of the two cars equipped with the same full hybrid 1.5 three-cylinder petrol engine (+ electric) with a total of 116 HP is really minimal. Let’s talk about 3.55 l/100 km for the Yaris Cross against the 3.60 l/100 km of the Yaris, an efficiency advantage of 1.39% for the Cross which translates into 0.18 liters of fuel less (12.78 vs 12.96 liters) and 30 euro cents (21.59 against 21.89 euros for the same price of petrol).

However, this small gap makes the result of the Toyota Yaris Cross exceptional, making it the most efficient crossover SUV among the full hybrids tested, third overall in the real consumption ranking behind the elusive Toyota Prius. More detailed information can be found in the real consumption tests of Toyota Yaris Cross Hybrid and Toyota Yaris Hybrid.
Same efficiency, even with increased sizes and weights
If we go even further into the detail of the two real fuel consumption tests and compare the measurements, weights and aerodynamics of the two Yaris, we discover that the differences are still minimal, demonstrating that the Yaris Cross project also remains devoted to maximum efficiency.
The credit is also due to the new common TNGA-B platform which forms the basis of both models, but above all to the fourth generation 1.5 liter Atkinson cycle engine which, for both cars tested, is homologated in the WLTP cycle with emissions of 112 g. / km of CO2.
All the numbers of the two challengers
For those who want to have fun finding the reasons for such close consumption between Yaris Cross and Yaris, we propose below a summary table with all the data useful for comparing the test, including the measurements, the mass of the two cars. Obvious are the larger dimensions of the Yaris Cross, as well as the greater weight and the larger trunk, all elements that confirm the exceptional result for the Cross.
We also report the external temperature and weather conditions during the test (rain for the Yaris, clear for the Yaris Cross). The more curious can also try to discover the aerodynamic penetration coefficient (Cx) of the two cars, not officially declared.
There is also the specification of brand, type and size of tires, another component that affects consumption. There rolling resistance of rubber, classified in theEuropean label according to an energy efficiency scale from A to E, it can in fact lead to a higher consumption up to 0.63 l / 100 km in the case of less virtuous tires (Fonte Nokian Tires). The Yaris Cross also has an advantage in this because it is equipped with category C tires against the D of Yaris.

Yaris at the top in mixed routes, Yaris Cross champion of economy run
As a further demonstration of the proximity between the consumption of the two Japanese hybrid cars, we add the detail of consumption in other driving situations. As you can see, it is a head to head really tough between Yaris Hybrid and Yaris Cross Hybrid.
|Toyota Yaris||Toyota Yaris Cross|
|Traffic in the city (Rome)||4.5 l/100 km||
4.4 l/100 km
|Mixed urban-extra-urban||3.8 l/100 km||4.2 l/100 km|
|highway||5.3 l/100 km||5.2 l/100 km|
|Economy run||3.2 l/100 km||2.9 l/100 km|
|Maximum consumption||15.7 l/100 km||16.1 l/100 km|
|Maximum autonomy in electric mode||5,5 km||5,0 km|
If in the tests in city traffic, on the motorway and in the maximum consumption test the result is essentially a draw, in the mixed urban / extra-urban route the Yaris seems to prevail and in the economy run the Yaris Cross does better.
