Help regarding Model Y RWD vs AWD

In Europe they just announced today a LR RWD Y with a 373 mile range. Wonder if it will be coming to the US. Having just sold our 2013 RWD model S and purchasing a MYLR, I would have been happy with an RWD Y if one could get it with some nice options.

For me, RWD versus AWD is more of a Sunbelt versus Snowbelt question. Having moved from a RWD S60 to AWD Y LR, I can say with certainty that AWD plus snow tires is a LOT better than RWD plus snow tires in difficult driving conditions.

Not something that the OP in the Bay Area needs to consider, I suppose. 😎

That link didn’t take me to a comparison of the two trim levels.

Try this link Vehicle Comparison Selector – TeslaTap, or check out the attachment. The RWDY has LFP Chinese batteries from BYD @ $56 per KW and the YLR has NCA Telsa/Panasonic Batteries.

This info may be true in some parts of the world but is not correct for the US Market and the OP is based in California. In the US, there are no Model Ys with LFP battery packs.

Tesla Model Y RWD Returns to the US Market With a LFP Battery and Updated Price

Tesla launched the LFP-powered Model Y RWD in the US as the new base model after retiring the Model Y AWD, built with 4680 battery cells
www.autoevolution.com www.autoevolution.com

The new Model Y RWD launched in the US retails for $43,990, which is $3,750 less than the discontinued Model Y AWD. It also benefits from the full $7,500 tax credit, which means Tesla either makes the battery pack in North America or can use the same trick it used with the Model 3 RWD built in Fremont with an LFP pack imported from China. The Model Y RWD has 260 miles (418 km) of range, 19 miles (31 km) less than the AWD model discontinued last month. It's also more sluggish, with a 0-60 mph (97 kph) time of 6.6 seconds compared to 5.0 seconds

You may be right they only mention Lithium-Ion, in the EPA report, but aren't both LFP and NCA both considered Lithium-Ion?

Why would the charging curve be so crappy with the RWDY then? Maxing @ 170kW, verses 250kW for the LRY?

Note the rear motor power in the RWDY is 203 kW or 272 HP versus 384 HP in the LRY


  • Lithium Iron Phosphate (LiFePO4) – LFP. LiFePO4 is one of the most recent cathode materials to be introduced. As of 2017, LiFePO4 is a candidate for large-scale production of lithium-ion batteries, such as electric vehicle applications, due to its low cost, excellent safety, and high cycle durability. The energy density of an LFP battery is lower than that of other common lithium-ion battery types, such as Nickel Manganese Cobalt (NMC). Because of their lower cost, high safety, low toxicity, long cycle life, and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. Working voltage = 3.0 ~ 3.3 V. Cycle life ranges from 2,700 to more than 10,000 cycles depending on conditions.
  • Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2) – NCA. In 1999, Lithium nickel cobalt aluminum oxide battery, or NCA, appeared in some special applications, and it is similar to the NMC. It offers high specific energy, a long life span, and a reasonably good specific power. NCA’s usable charge storage capacity is about 180 to 200 mAh/g. The capacity of NCA is significantly higher than that of alternative materials such as LiCoO2 with 148 mAh/g, LiFePO4 with 165 mAh/g, and NMC 333 (LiNi0,33Mn0,33Co0,33O2)with 170 mAh/g. The voltage of these batteries is between 3.6 V and 4.0 V, at a nominal voltage of 3.6 V or 3.7 V. Another advantage of NCA is its excellent fast charging capability. Nevertheless, its weak points are the limited resources of cobalt and nickel and the high cost.

There is no trick with the RWD Model 3 as it is *not* eligible for the Fed tax credit because it uses an LFP pack made in China.

I didn't write that, it's a direct lift from the article I posted from AutoEvolution source document I linked to.

All Model Y's are eligible for the $7500 if your income is within the range, and even if you make over the income range if you lease you get the full $7500 credit anyway, its just spread evenly over the lease payments.

I bought both a Model LRX and LRY this year, so we had to put one in my son's name so he could get the credit, and one in my wife's name, so she could get the credit. If I get a LRS this year, I will lease it so I can get the Tesla lease incentive of $7500, but we may hold to see if the CT shows up.

I have a rwd model 3 in Wisconsin and with winter tires that thing is a beast. Remember its not like a pickup truck where there is no weight over the drive wheels. Plus they plow the roads here so fast and use so much road salt that the roads are clear quickly.

I have to get up a 270 foot steep, curved driveway in winter. There is no comparison between my many years with the Model S RWD with snow tires and the Model Y AWD with snow tires. I did a lot less shoveling this past winter because the Y could push through the snow and icy spots most of the time, unless the new snowfall was too deep. I agree that on plowed and sanded roads, RWD plus snow tires is fine — the main safety concern is stopping and sharp curves. The S stopped dead straight in slick conditions every time. Modern traction control and ABS are amazing!

Snowing hard here in the mountains right now, by the way. Too warm for accumulation, however.

Yes that is a ABS traction control thing, NOT a AWD vs RWD question.

Where I live I use studded tires since I have a very steep hill that is only sanded and no slat is used so it is often icey, I had AWD cars with very good snow/ICE tires and FWD and RWD cars with studded tires and any day the studded tires in the icey conditions would beet the AWD with winter tires.

So I now have a RWD MY with studded tires during the winter and love it; the traction control is great and when needed I use the snow traction option to spin just a tad when starting on street corners.

^ Yes stoping has nothing to do with RWD or AWD, although tires matter a lot!

Studded tires are best for ice, as you say, but they are hard on roads so I haven't used them in recent years, although they are legal here. I mostly push through snow and ice is less common in Colorado than in the East. Warm heavy snow is the most difficult, sometimes it is hard to walk on it is so slippery (we use Yaktrax). The extra traction from AWD helps to get going in such conditions. It greatly reduced my need to shovel my long driveway this winter. Shady spots stay snowpacked most of the winter.

Since most of my driving is on clear dry roads in sunny Colorado, the snow tires are a compromise between that and dealing with snow when it happens.

Cold snow has the best traction for driving and walking. Heavy spring snow can be a nuisance, although the extra water content is very welcome here in the dry West!
