I just saw a video from a EV company here in the UK comparing a Tesla S Long Range dual motor to an EQS 450+ Lux.

I've linked the video below. Knowing those roads, it's a reasonable approximation in a very real world UK situation. The clinical accuracy I have no idea about but it scans ok.

The summary gave the EQS the result on range (376 miles) and the Tesla the result on efficiency.

But it sparked comments about wheel size. If the comments are correct then there is a significant benefit in optioning the 21" wheel over the 22" wheel. Interestingly the Tesla had a 19" wheel which would give greater range again.

EQS wise, the 21" wheel (allegedly) would give a 10% range benefit or an extra 50 miles. I've not checked the validity of the maths but that's a fair amount more.

One EQS owner / driver in the US mentioned that he was getting a practical and reliable 410 miles at 75 on motorways with his 21`" wheels. Again that's quite an uplift over the tested 376 miles. Not the 50 miles mentioned elsewhere in the comments but still a good bit more ..... the journey between Central London to Heathrow T5 and back or Manchester to Sheffield if my maths is right.

Interested what size wheel you went with and if this range aspect was a factor?

Here's the video comparison .....

Range-wise, smaller wheel size is better for EQS range is my understanding.

19" offers 471 miles WLTP according this -

Configuring wheels on Mercedes EQS can add 76 km of range

Configuring the correct wheels on the Mercedes EQS can optimize the range, or the lack thereof can see the range take a 10% hit.

Following up last post, larger wheel sizes will have their own advantages such as generally shorter braking distance-

The video summarizes-

Older Tesla has 14.97kwh/100km "real world UK" efficiency and 352 mile "real world UK" range.

EQS with least efficient wheels has 18.22kwh/100km "real world UK" efficiency and 376 mile "real world UK" range.

As EQS WLTP range based on linked article is 759km for 19" vs 683km for 22", doing some calculation might give an approximation of "real world UK" EQS using 19".

[Original test result] 376 miles * [simple adjust for 19" WLTP improvement] (759 / 683) = [EQS range in real world UK] 418 miles

Therefore with 19" wheels, his test might give the EQS "real world UK" range within 5 miles of 418 miles with 19", compared the Tesla got 352 miles with 19". Therefore EQS has almost 20% more range compared the older Model S AWD though it would be interesting to have used a 2022 Model S for comparison or a RWD older Tesla too (RWD isn't available for Tesla anymore since 2017 I understand)

So also the real world advantage would be about 26 miles by my calculations for 22" vs 21", or even less miles in Winter. Going by WLTP scores in above linked article, 21" would give a 49km advantage compared 22" (732km vs 683km). Or "real world uk" advantage of about [difference of 732 to 683] 49 * [convert WLTP to real world UK] 605/683 = 43km which is 26 miles.

In the EQS configurator in UK, "luxury" trim only allowed me choose 22" wheel interestingly. The cheaper the trim, the smaller the wheel tends to be ("premium" trim 21 inch and cheapest "line" version 20 inch). So there is no wheel size choice in UK except indirectly, unless special order it seems. And range doesn't seem to be much of a consideration. Aesthetics especially size seems to be.

In summary, personally I think I am a "classic" Mercedes-Benz customer, so would likely order the best-selling Exclusive Luxury or Luxury trim, so would receive 22". Would I special order or get later on the 21" just for maybe 15 mile advantage in the worst weather? I would probably consider 19" instead if range was the most important but would be aware of braking distance. If you go on a non-packaged configurator you can see these 19" wheels.

All I can tell you is I now own an EQS 450+ with 21” wheels after driving 3 MSs. The last two were a 2017 S100D and a 2021 MS LR (horrid car!). They all had the standard 19” wheels. Like everything Musk, on range, Tesla over promises and underdelivers. Mercedes, as many reviewers have pointed out, does the opposite, and that has been my experience. The 450 out performs the S on road trips.
