Car fuel and emissions information

[Martin J 76]

In an idle moment recently I downloaded the latest car fuel and emissions information spreadsheet from the VCA at

https://carfueldata.vehicle-certification-agency.gov.uk/downloads/default.aspx

Dearly though I love my NX, this confirmed what many here have noted over the last couple of years: the current NX drivetrain is inefficient and not as green as we might have liked to think.  Particularly interesting that the RX, despite its weight and power, achieves very similar WLTP CO2 emissions and fuel consumption figures. The new TNGA-based RAV4 performs much better.  The NX's aesthetics still look crisp and fresh (I hope Lexus don't mess up the next generation, or tone it down), but underneath it's showing its age.

Honest John's real mpg figures:

NX 300h   37.8 mpg,      RX 450h   34.0 mpg,      RAV4 Hybrid 4WD  47.7mpg

Undoubtedly spot on. Looks need to be kept for the next gen, perhaps even crisper, but the drivetrain needs a nice more-performance, better-economy improvement as per RAV4. I have no doubt this is exactly what it will get! 🙂

I was quite taken with the new RAV4 hybrid when I saw one in the local Lexus/Toyota dealership.

^^ I get slightly above that for the NX - 39-41mpg most of the time - but got slightly below that when I had the latest RX for three months. On the motorway at the legal speed limit I struggled to get the RX above 30mpg whereas the NX manages 35mpg in the same situation.

However, the real killer stat is that for the latest RAV4. Now that Toyota have done thorough user testing on the new platform they can drop it into a Lexus...😂

Sorry, not familiar with the specs of newer cars ........ is the engine in the RAV4 Hybrid the 2.0 litre petrol like the Corolla to get these figures?

If you are really that worried about fuel consumption, you shouldn’t own a car.

just fill up when empty and enjoy.

No it's still a 2.5L. Presume a combo of a larger Battery, lighter weight and changes to the hybrid system help.
