- Need the space? Buy the Model Y. A 971 L total cargo capacity (vs 649 L), higher seating, more towing and an optional kids-only third row make it the family pick.
- Don't need it? The Model 3 is the smarter buy. Cheaper to buy (~€33k vs ~€34.5k effective, and ~€6.5k less on list), more efficient, slightly more real-world range, quicker and sharper to drive — and about €3,450 cheaper to own over five years.
- Everything technical is identical: same platform, batteries, 175/250 kW charging, Supercharger network, software and 8-year battery warranty. This is a body-style decision, not a tech one.
- Range: same 534 km WLTP, but the lower, slipperier Model 3 goes further in the real world (~415 vs ~380 km).
- Resale: effectively level (~52% at 5 years), with the Model Y perhaps a touch stronger on SUV demand.

The pattern is unusually clean because it's the same car in two shells: the Model 3 wins everything that follows from being lower and lighter (price, efficiency, range, pace, cost); the Model Y wins everything that follows from being taller and bigger (cargo, access, towing, seats). All the Tesla tech — charging, network, software — is a tie.
Price & SEAI grants
Both qualify for the same Irish EV incentives — the SEAI€3,500 purchase grant (Standard variants, under the €60,000 OMV ceiling), VRT relief, the €600 home-charger grant and €120 flat motor tax. The Model 3 is the cheaper way in: it lists below the Model Y (€36,484 vs €42,990 — a ~€6,500 gap), and Tesla's €3,500 trade-in bonus (running to mid-2026) narrows the effective gap to about €1,500. Check whether the bonus also applies to the Model Y when you order, as Tesla promotions shift.
| Variant | Tesla Model 3 | Tesla Model Y |
|---|---|---|
| Value / RWD pick | Standard RWD ~€32,984 effective | Standard RWD ~€34,490 effective |
| Long-range pick | Long Range RWD ~€44,000 (702 km) | Premium RWD ~€43,490 (622 km) |
| Performance / AWD | Performance €59,990 (3.1 s) | Long Range AWD ~€53,000 · Performance ~€60,000+ (3.7 s) |
| Motor tax | €120/yr (BEV) | €120/yr (BEV) |
Verdict on price: Model 3. It's cheaper at every equivalent tier and meaningfully cheaper on list. The Model Y's premium buys you the extra body — whether that's worth ~€1,500 (effective) to ~€6,500 (list) is the heart of this decision.
Saloon vs SUV — the whole decision
The Model 3 and Model Y share well over half their parts, the same drivetrains and the same tech. The Model 3 is a low saloon — 1,441 mm tall, more aerodynamic (Cd 0.22), lighter and sharper to drive. The Model Y is a tall SUV — 1,624 mm high, with a raised seating position, a hatchback tailgate and far more cargo space. Everything else that defines a Tesla is common to both.
What the body change actually gives you
- Choose the Model 3 for: a sleeker look, a lower centre of gravity and the sportier, more planted drive; better aerodynamics (so more real-world range); a lower price; and easier parking in the saloon's slightly tidier footprint.
- Choose the Model Y for: a much bigger boot with a tall hatchback opening; a higher seating position that's easier for child seats, older passengers and dogs; more towing; and the option (Long Range AWD) of a kids-only third row.
- Driving feel: the Model 3 feels noticeably sharper and lower; the Model Y is comfortable and commanding but rolls a little more and uses a bit more energy for the same journey.
Verdict: it's a needs test, not a quality gap. Neither is "better" — the Model Y is the more practical car, the Model 3 the cheaper and more engaging one. Globally the Model Y outsells the Model 3, which tells you most buyers value the space; but plenty don't need it, and for them the 3 is the savvier buy.
Range & efficiency
| Item | Model 3 Standard RWD | Model Y Standard RWD |
|---|---|---|
| Battery (usable) | ~64 kWh LFP | ~62 kWh LFP |
| WLTP range | 534 km | 534 km |
| Real-world (mixed) | ~400–430 km | ~380 km |
| Efficiency | ~14 kWh/100 km (Cd 0.22) | ~16 kWh/100 km (Cd 0.23) |
| Most-range variant | Long Range RWD — 702 km WLTP | Premium RWD — 622 km WLTP |
Verdict on range: Model 3. The two Standard RWDs quote the same 534 km WLTP, but the lower, lighter, more aerodynamic Model 3 turns that into more real-world kilometres (~415 vs ~380) and is the more efficient car to charge. If you want maximum range from either, the Model 3 Long Range's 702 km is the highest in the family short of the priciest Model Y versions. For most Irish driving, both Standards comfortably cover a week of commuting between home charges.
Boot, space & towing
| Item | Tesla Model 3 | Tesla Model Y |
|---|---|---|
| Length | 4,720 mm | 4,790 mm |
| Height | 1,441 mm | 1,624 mm |
| Boot (rear) | 561 L | 854 L |
| Frunk | 88 L | 117 L |
| Total cargo | 649 L | 971 L |
| Cargo (seats folded) | ~1,300 L | 2,158 L |
| Towing (braked) | 1,000 kg | 1,600 kg |
| Seats | 5 | 5 (kids-only 7 on LR AWD) |
Verdict on practicality: Model Y, comfortably. This is the whole reason the Model Y exists. Its hatchback tailgate and taller body give 971 L of total cargo versus the Model 3's 649 L — and over 2,000 L with the seats down, near estate territory. It tows 60% more, sits you higher for easier access, and offers the kids-only third row the Model 3 can't. The Model 3's 649 L is genuinely good for a saloon (bigger than many hatchbacks), but it's not in the same practicality bracket.

Enquire about sponsorship →Real running costs — annual (Standard RWD, 20,000 km/year)
| Item | Model 3 Standard RWD | Model Y Standard RWD |
|---|---|---|
| Home electricity (night rate) | ~€270 | ~€420 |
| Public / Supercharger DC | ~€200 | ~€220 |
| Motor tax | €120 | €120 |
| Insurance (group) | €900–€1,500 (grp 28–35) | €900–€1,500 (grp 30–37) |
| Servicing (as-needed) | €100–€200 | €100–€200 |
| Depreciation (year 1) | ~€4,000 | ~€4,500 |
| Annual total (excl. finance) | ~€5,400–€6,100 | ~€6,200–€7,000 |
Verdict on running costs: Model 3. Same €120 tax and the same near-zero Tesla servicing, so the gap is the Model 3's better efficiency (it charges cheaper) and slightly lower depreciation and insurance — roughly €800 a year less to run. Both are far cheaper than any petrol equivalent.
5-year total cost of ownership
Total cost over 5 years / 100,000 km (median Irish driver, 5+ years NCB, mostly home charging):
| Item | Model 3 Standard RWD | Model Y Standard RWD |
|---|---|---|
| Electricity (5 yr) | ~€2,350 | ~€3,200 |
| Motor tax (5 yr) | €600 | €600 |
| Insurance (5 yr) | ~€5,500 | ~€5,500 |
| Servicing (5 yr) | ~€700 | ~€700 |
| Depreciation | ~€18,000 | ~€20,500 |
| Tyres + consumables | ~€700 | ~€800 |
| 5-year total cost | ~€27,850 | ~€31,300 |
| Cost per km | ~€0.28 | ~€0.31 |
The cheaper car over 5 years is the Model 3, by about €3,450 — driven by its lower purchase price, better efficiency and larger absolute depreciation saving (it costs less to begin with). At €0.28 vs €0.31 per km both are among the cheapest family cars to run in Ireland; the Model 3 is simply the leaner of the two. If you'll use the Model Y's space, that extra ~€700/year is the price of the practicality — if you won't, it's money left on the table.
Depreciation & resale retention
| Retention | Model 3 Standard RWD | Model Y Standard RWD |
|---|---|---|
| 1-year | ~80% | ~80% |
| 3-year | ~62% | ~62% |
| 5-year | ~52% | ~52% |
Verdict on resale: effectively a tie. On our figures they retain the same ~52% at five years. In practice the Model Y may hold a fraction better because SUV body styles are in slightly stronger used demand, but the difference is within the noise. Both depreciate faster than petrol cars — Tesla's periodic new price cuts devalue used stock — and both stabilised after the 2024–25 refreshes. A complete service history and the transferable battery warranty matter more to resale than which body you chose.
The verdict — overall winner & per-buyer picks
If you need the space, buy the Model Y; if you don't, the Model 3 is the smarter buy. They share the same platform, batteries, charging, Supercharger access and software, so this is almost purely a body-style decision — the Model 3 is cheaper to buy and run, more efficient, slightly longer-range and the sharper drive, while the Model Y trades all of that for a much bigger boot, higher seating and more towing. There's no wrong answer on the EV fundamentals; pick the shape your life actually needs.
- Best value / lowest cost → Model 3. Cheaper to buy and ~€3,450 less over five years.
- Most efficient / most range → Model 3. ~415 km real vs ~380, and a 702 km Long Range option.
- Sharpest, sleekest drive → Model 3. Lower, lighter, more planted.
- Maximum boot / family hauling → Model Y. 971 L vs 649 L, and 2,158 L seats-down.
- Higher seating / easy access / dogs / child seats → Model Y. The raised SUV body earns its keep daily.
- Towing or an occasional 3rd row → Model Y. 1,600 kg and a kids-only 7-seat option.
Sit in both, put whatever you carry most — buggy, dog crate, sports kit — in each boot, and the answer usually picks itself. If it fits the Model 3, save the money and enjoy the sharper car; if it doesn't, the Model Y's space is worth the modest premium.
