The (Euro) WLTP range and efficiency ratings for the 2018 LEAF have been published by pushevs.com, and they may indicate better-than-expected efficiency and range for the 2018 LEAF.

Pedro, reports correctly below that the two test cycles seem to produce similar results but incorrectly states that "we know the expected combined EPA range for the 2018 Nissan Leaf is 150 miles".

So the 168 and 177 mile ranges below may indicate a significant upside surprise in the 2018 LEAF efficiency/capacity and EPA range.

2018 Nissan Leaf gets WLTP ratings

Nissan Austria just released the WLTP range and efficiency figures for the new 2018 Nissan Leaf.

...Version

Visia and Acenta (16 inch wheels)

N-Connecta and Tekna (17 inch wheels)

WLTP city range

415 km (257 miles)

389 km (242 miles)

WLTP combined range

285 km (177 miles)

270 km (168 miles)


WLTP combined efficiency

19,4 kWh/100 km

20,6 kWh/100 km

Notice that WLTP efficiency figures measure plug-to-wheels consumption, this means that the onboard charger efficiency matters. Nonetheless, as the reader Rodrigo Melo noticed, the combined efficiency and range figures don’t add up. Or the combined range figure is wrong, or it’s the efficiency. I think that the error it’s in the range… As we know the expected combined EPA range for the 2018 Nissan Leaf is 150 miles (241 km), and we’ve seen that the EPA and WLTP combined ranges on the Chevrolet Bolt EV are very similar. For this reason the combined WLTP range on the new Nissan Leaf should be around 150 miles (241 km), then the efficiency and range ratings add up...

Amazing that Nissan has been able to keep this under wraps, with the official launch being only days or weeks away.

If you see any 2018 LEAFs on a delivery truck, see if you can get a look...

disappointing...

2018 Nissan Leaf

Combined MPG:112 MPGe

City MPGe:125 Highway MPGe:100...


30 kWh/100 mi
EPA range: 151 miles

With the lower profile, how could it not improve on the 2017 LEAF's highway efficiency?

Those numbers are virtually identical to the ones for the 2017 LEAF, which is 124 MPGe City and 101 MPGe Highway:

I wonder if the 2018 LEAF's efficiency numbers are so much worse than those for the 2018 Tesla Model 3 simply because of poor charger efficiency:

Very strange that Bolt performs about the same on the WLTP, 380 km (= ~236 miles) as the 238 miles on the EPA combined, while the LEAF performs so much worse on EPA, 151 as opposed to its WLTP 177/168 miles, as reported here:

https://pushevs.com/2018/01/11/2018-nis ... p-ratings/

...The Ampera-e has a certified range of 320 mi (520 km) under the New European Driving Cycle (NEDC) test cycle with a full battery, and achieved a range of 240 mi (sic?) (380 km) under the more strict Worldwide harmonized Light vehicles Test Procedures (WLTP)...

The “second gen” Leaf is really more like Leaf 1.5. All the hard parts of the chassis and unit body are the same; it’s the ‘11-‘17 with a better battery, inverter, and a new front clip.

Given this I’m not surprised that the ‘18 MPGe ratings are so similar to the old car.

Testing aside, with one pedal some will do MUCH better than EPA...

Why do you think that? I get the impression that one-pedal might cause more application of the brakes than a human would if hypermiling using two pedals.

With the exception of high SOC, deceleration is all regen so a much greater return of power over the previous method. You can go from 50 mph to a complete stop in less than half a block. It would take some time to get used to getting the right amount of deceleration but I personally don't think it will take long for the average person to get the hang of it.
