Exterior Dimensions
Legacy Model 3's footprint is 1 inch shorter than Highland (184.8 vs 185.8) and 0.1 inch taller (56.8 vs 56.7). Width and wheelbase are identical between generations — same 72.8-inch width and 113.2-inch wheelbase. This is why exterior accessories (wheel covers, roof racks, mud flaps) cross-fit most Legacy years onto Highland. Ground clearance is 5.5 inches — roughly the same for all Legacy variants except the Performance trim, which sits slightly lower on 20-inch wheels.
Cargo & Storage
| Compartment | Volume | Note |
|---|---|---|
| Rear trunk (seats up) | 15.0 cu ft | Slightly smaller than Highland's 21 |
| Under-trunk well (sub-trunk) | ~4 cu ft | Charging cable + tire repair kit |
| Rear seats folded | ~19 cu ft usable | Mountain bike with front wheel off |
| Frunk | ~3 cu ft | Two grocery bags |
Legacy's trunk opening is narrower than Highland's and has a prominent lip at the rear seat base — items over 24 inches tall need to go in sideways or with the rear seats folded. The 60/40 rear seat split lets you carry skis, 2×4 lumber up to 7 feet, and surfboards with the passenger-side seat folded.
Range, Weight & Performance by Trim
| Trim | Years | EPA range | 0–60 mph | Top speed |
|---|---|---|---|---|
| Standard Range | 2017–2019 | 220 mi | 5.6 sec | 130 mph |
| Standard Range Plus | 2019–2020 | 240–263 mi | 5.3 sec | 140 mph |
| Mid Range | 2018–2019 | 264 mi | 5.6 sec | 125 mph |
| Long Range RWD | 2017–2019 | 310–358 mi | 5.1 sec | 140 mph |
| Long Range AWD | 2018–2023 | 310–330 mi | 4.2–4.4 sec | 145 mph |
| Performance | 2018–2023 | 299–322 mi | 3.1 sec | 162 mph |
Battery pack capacity varied by trim and year: 50 kWh (Standard Range), 62 kWh (Mid Range), 75–82 kWh (Long Range and Performance). DC fast charging peaks at 170 kW on early RWD cars and 250 kW on later Long Range/Performance trims (post-2020). Home AC charging is 11 kW for all Legacy trims.
Frequently Asked Questions
How do I tell if my Model 3 is Legacy or Highland?
Check the steering wheel and shifter. Legacy has physical stalks for turn signals and gear shifting. Highland has capacitive buttons on the wheel and a touchscreen swipe for shifting. Build year is not reliable — some early-2024 Legacy cars sold in specific markets. If you still have physical stalks, you own a Legacy and every Legacy-fit accessory applies.
Will a 2024+ Highland accessory fit my 2022 Legacy?
Exterior body accessories usually cross-fit because the shell is dimensionally identical within millimeters. Interior accessories — floor mats, console organizers, trunk liners, anti-kick mats — usually do not because Highland reshaped the console, dash, and rear footwell. Order by year-range fitment labels and avoid "all years" listings, which often miss one or the other.
What is the actual trunk capacity on a Legacy Model 3?
Tesla's official figure is 15 cu ft for the rear trunk with seats up, plus ~4 cu ft of sub-trunk storage under the floor panel. Folding both rear seats opens ~19 cu ft of usable cargo space. The frunk adds another 3 cu ft. Shopping for a family trip, plan for two mid-size suitcases plus a weekend bag — not four.
Can a Legacy Model 3 tow anything?
Tesla does not rate Legacy Model 3 for towing in North America — there's no factory tow hitch or rated tongue weight. In Europe, the Long Range and Performance are rated for 1,000 kg (2,204 lb) braked. North American owners install aftermarket Stealth Hitches rated for 2,000 lb tongue, though this voids the factory warranty on suspension components.
How low is ground clearance, and what shouldn't I drive over?
Legacy sits at 5.5 inches (140 mm) of clearance — very tight for a passenger car. Unpainted speed bumps, steep driveway transitions, and snow berms all risk scraping the front splitter or battery pan. Approach speed bumps at an angle and avoid forest service roads. The battery case is structural; scraping it leaves marks but no functional damage under 15 mph.
