Tesla Model Y Buyers Guide

Last updated 09-Jan-2022

The Tesla Model Y has been available since 2020 and only in America including the USA, Canada and Mexico until now (May 2021). While it has not been out long, there are an ioncreasing amount of used cars available for purchase as well as well as new inventory. We run through the history, albeit short, the options, what we think are the common issues and make some suggestions on what to buy.

Why the Model Y?

Tesla Worldwide Inventory Search

You may already know the Model Y is the car you want, and we have a guide to the Tesla model differences. It is worth reflecting briefly on the other choices for similar money. The main alternative to the Model Y is the Model X for practicality. These are larger and more premium and while even an early Model X is likely to be more expensive than a Model Y to buy, we think the depreciation on the Model Y is likely to mean it costs less over time. The Model 3 is the other alternative on price, and even the Model S could be a viable alternative. In many regards, the Model Y is the fusion of all those other cars rolled into one.

Alternatives

The Model Y is in the hottest segment of all EVs, the compact SUV, and as such has the most competition. Which you chose really depends on what you value most. There are cheaper but less capable cars such as the ID3, Enyaq and MG, and around the same price cars such as the the ID4, Ioniq 5, EV6 and even cars such as the BMW i3x are all very credible cars. The Model Y is expensive to us for what you get, but if range is king in your book then it wins, although for those that rarely need to rapid charge away from home, the others all have some compelling benefits.

New or used?

The Model Y is widely available as new, nearly new or used cars, and we've a guide to saving money buying a Tesla which covers the different choices in more detail. The key differences in summary however are:

History of changes

While the Model Y is still relatively new there have been a number of changes. The two main areas are the battery which has seen some small capacity upgrades and the MCU (media control unit) which from late 2021/early 2022 has started to shipped with the later Ryzen processor as used in the 2021 Model S. This does not seem to be consistent from country to country but finding cars with the later processor will help future proof the car going forward.

For a full list of the changes and in which year see our guide to Tesla model history and changes over time.

Battery size and range

The Model Y comes in Standard Range RWD, Long Range AWD and Performance AWD although the Standard Range has now been dropped as a new order. For most buyers the choice really is the Long Range unless they want the marginally better performance of the Performance model.

The Model Y is one of the more efficient EVs you can buy, but that efficiency also means any changes in inefficiency can be magnified. The WLTP and EPA test results are also fairly limited in what they tell you as the weather, driving style and speed can all cause significant fluctuations in the available range. In cold weather energy is required to heat the cabin and the car efficiency is reduced as the battery warms up, the smaller the battery the larger the proportion of available energy goes to heating, as a result stop start journeys in winter are worse than a single continual drive, and we've a page dedicated to cold weather driving to provide tips on how to improve range. Our rule of thumb is in winter, the cars can do approximately 80% of the rated range, but you should also allow a 10-20% buffer to reach a working range as you will neither want to regularily charge to 100% or finish the journey with less than 10%.

Battery codes

Tesla use 2 different conventions for naming batteries. In the car configuration which you can sometimes access through MyTesla and can see when looking at inventory cars they use a code such as BT37, whereas on formal import paperwork they use a code such as EC5D. Websites like TMC often discuss the batteries using the EC5D type codes but potential buyers then have difficulty matching that to inventory in their region as Tesla don't use these codes in their inventory listings. The table below helps match one to the other:

Standard Range+ when it was available

Each Tesla has a model code which is a combination of various factors including the battery. There are a surprising number of permutations which list int he table below. This is important the model code is relatively easy to find in MyTesla just by looking at the image link of the car. From this model code you then determine the battery code and using the table above the alternative battery code if you so wish.

Model codes

Tesla give each model an internal code which changes when updates to the battery or motors occur or when changes such as the addition of a heat pump can make a material difference. We have covered elsewhere how you find your version number but for the Model Y these all start MTYxx. We list the versions, the battery code, and the key performance data.

It is worth noting that Tesla list performance model specifications with 1 foot roll out. This reduces the time by approx 0.2s, so this should be added to the 0-60 times to get a comparable time to those of the other models.

Autopilot

All Model Y cars come with Autopilot hardware so the only material choice is the software level installed. Autopilot is standard on most, we feel paying a little extra for Enhanced Autopilot or Full Self driving is worthwhile with Enhanced Autopilot as an after purchase option a sensible option if you can make use of the features. Our estimation is FSD adds about 5-7% to the value of a car, so if you are looking at a car with FSD and one without, expect to pay about $3k more. We don't feel the $10k/£8k asking price from Tesla is ever reflected in used car prices.

Options

The model Y is fairly light on options besides colour and interior. There are however a few to look out for:

Free Supercharging

No Model Y came with unlimited free supercharging for the life of the car. Tesla have however offered a year free supercharging to cars delivered at the end of 2020. It is not clear if this is transferable to new owners within the year, generally speaking since 2017 any free supercharging given to new car buyers has not been transferable..

Key issues

The Model Y was a new platform and Tesla seem to have learnt from a number of the previous issues, however they have also introduced some new ones. Most of the issues are factory issues and not ones that develop over time so the owner or a good condition car is likely to run into fewer problems over time, however getting a car in good condition can be harder than it should be because of Tesla's stance.
