BMW F30 vs F31: Saloon or Touring 3 Series?
F30 saloon or F31 Touring is the question every UK 3 Series buyer with a family eventually asks. Mechanically identical: same chassis, same engines, same gearboxes, same trim levels. Different practicality and a key chassis difference: F31 Touring has standard rear self-levelling air suspension; F30 saloon has conventional rear springs. This guide covers the saloon-vs-Touring buyer trade-off.
Quick verdict
F31 Touring for families and dog owners; F30 saloon for single drivers, couples, and anyone who prefers the cleaner saloon styling. F31 commands a small used premium (~£500-£1,500) for the practical boot. Key chassis differentiator: F31 has rear self-levelling air suspension as standard (which can fail at 80k-130k miles, £400-£900 per side) while F30 has conventional springs. Engines, ULEZ status, and reliability are identical.
Side-by-side comparison
| Dimension | F30 | F31 | Notes |
|---|---|---|---|
| Body style | 4-door saloon | 5-door Touring (estate) | Single biggest practical difference. |
| Boot space (seats up) | 480 litres | 495 litres | F31 slightly larger seats up. |
| Boot space (seats folded) | 1,170 litres (60/40 fold) | 1,500 litres (40/20/40 fold) | F31 wins meaningfully on max load. |
| Rear suspension | Conventional rear springs | Standard rear self-levelling air | F31 has a known wear item the F30 doesn't have. |
| Real-world UK MPG | Same as F31 within engine variant | Same as F30 within engine variant | Identical engines; same fuel cost. |
| Insurance group | Same as F31 within trim | Same as F30 within trim | No insurance differential. |
| Length (mm) | 4,624 | 4,624 | Identical length. |
| ULEZ compliance | Build-date dependent | Build-date dependent | Identical rules: post-LCI B47 / B48 are Euro 6 ULEZ-compliant; pre-LCI N47 / N20 diesel is not. |
| Used pricing (M Sport equivalent) | F30 saloon = baseline | F31 Touring = baseline + £500-£1,500 | F31 commands modest premium for boot. |
| M3 variant available | F80 M3 (separate chassis) | No M3 Touring in F-gen (G81 was first M3 Touring) | F30 has the F80 M3 saloon sister; F31 has no M3. |
F30: deeper look
F30 saloon (2012-2019) is the modal UK 3 Series of the F-chassis era. 480-litre boot is generous for the saloon class. Same engines as F31: N47 / B47 diesel, N20 / B48 petrol, N55 / B58 petrol I6, plus the separate F80 M3 saloon (S55 twin-turbo M-engine). M Sport spec is the modal UK used buy. The F30 used market is enormous; pricing is the most predictable in BMW's lineup. The right pick for buyers who don't need Touring practicality and prefer the cleaner saloon styling.
F31: deeper look
F31 Touring (2012-2019) is the practical version of F30. Same fundamentals plus 5-door practicality and the meaningfully larger 1,500-litre seats-folded boot. Key chassis difference: standard rear self-levelling air suspension (not optional on F31). This adds long-term wear at 80,000-130,000 miles (£400-£900 per side to replace air bags). No M3 Touring in F-gen (G81 M3 Touring 2022+ was the first M3 wagon). M340i Touring (B58 374 bhp) exists in F31 spec and is the practical-hot-Touring pick. F31 is the UK family 3 Series of the 2010s.
Decision logic
Two filters decide F30 vs F31. First: do you carry stuff regularly (kids' kit, dogs, sports gear, etc.)? F31 wins on boot. Second: do you mind the rear self-levelling air suspension long-tail expense? F31 standard fitment becomes a £400-£900 per side wear item at 80,000-130,000 miles. F30's conventional springs don't have this concern. Outside these two filters, F30 and F31 are mechanically identical. F31 commands £500-£1,500 used premium for the practical body.

| Scenario | F30 | F31 | Notes |
|---|---|---|---|
| 2014 320d M Sport, 80,000 miles | £8,500 to £11,500 | £9,500 to £12,500 (F31 equivalent) | F31 commands ~£1,000 Touring premium. |
| 2017 320d M Sport LCI, 60,000 miles | £13,500 to £17,000 | £14,500 to £18,500 (F31 equivalent) | Post-LCI; ULEZ; F31 retains modest premium. |

| 2018 340i M Sport LCI, 40,000 miles | £19,000 to £24,000 | £20,500 to £26,000 (F31 340i Touring equivalent) | B58 petrol; the enthusiast Touring is rare and commands strong premium. |
| 2019 M340i xDrive Touring, 30,000 miles | n/a (M340i is G20 saloon era; was F30 not F31 spec) | £22,000 to £27,000 (G20 M340i Touring is G21) | M340i Touring is G21 spec, not F31; check chassis. |
Recommendation by scenario
| Scenario | Pick | Why |
|---|---|---|
| Single driver / couple, no kids | F30 saloon | Saloon styling, no air suspension long-tail expense, slightly cheaper used buy. F31's extra boot capacity is unused. |
| Family with school-age children | F31 Touring | The 1,500-litre seats-folded boot handles family gear, school kit, kids' sports stuff, prams. Worth the £500-£1,500 saloon-vs-Touring premium. |
| Dog owner (medium/large breed) | F31 Touring | 5-door access is meaningfully easier for dog loading; flat boot floor with seats folded; no rear-bumper height issue. |
| Long-distance commuter / 4 to 6 occasional passengers | F30 saloon | Saloon is fine for occasional rear-seat use; saves the air suspension long-tail expense. |
| Sports kit / cycling / surfing | F31 Touring | Touring boot fits standard bikes with front wheels off; roof bars are direct fit. Saloon needs a roof box for the same volume. |
| M Performance want (M340i) | F31 Touring (M340i Touring) | M340i Touring is rarer than M340i saloon and increasingly appreciating. The practical fast 3 Series of the late F-gen. |
| Tight budget (sub-£10,000) | Whichever clean F30 / F31 you find first | At this price point the £500-£1,500 saloon-vs-Touring premium isn't the binding constraint; service history and EGR recall completion are. Buy the right car regardless of body. |

Frequently asked questions
Is the F30 or F31 more reliable?
Identical. Same chassis, same engines, same gearboxes. The only mechanical difference is that F31 has standard rear self-levelling air suspension (which adds a £400-£900 per side wear item at 80,000-130,000 miles). F30 has conventional springs (no wear concern). Otherwise reliability is identical across both bodies.
Is the F31 air suspension a deal-breaker?
No, but it needs budgeting. Universal wear item at 80,000-130,000 miles. Air bag £200-£400 each side; compressor £400-£800 if worn. Total exposure £400-£1,200 over the F31's ownership life. F30 saloon avoids this entirely. Factor it into the £500-£1,500 Touring premium and the F31 is still good value for practical use.
Is there an F31 M3 Touring?
No. The F-generation 3 Series never offered an M3 Touring. The G81 M3 Touring (2022+) is the FIRST ever M3 estate. If you want an F-gen fast Touring 3 Series, the closest is F31 340i M Sport (B58 326 bhp). The F31 M340i and M340i xDrive Touring are NOT F31 spec; M340i is a G20-era model (G21 Touring).
F30 saloon vs F31 Touring fuel economy?
Identical. Same engines, same gearboxes, same kerb weight (within ~30 kg). Real-world MPG is the same. The Touring's extra body length doesn't change fuel cost.
Can the F31 boot fit a typical large suitcase plus 2 cabin bags plus a buggy?
Yes. 495 litres seats up is enough for a family-of-4 holiday load (1 large suitcase + 2 cabin bags + 1 buggy + miscellaneous). F30 saloon's 480 litres is also workable but the boot opening is smaller and harder to load high items. F31 wins on practical access.
F31 Touring or F11 5 Series Touring?
F31 (3 Series Touring): 495 L boot seats up, 1,500 L folded; F11 (5 Series Touring): 560 L seats up, 1,670 L folded. F11 is bigger across all dimensions and runs 6-cylinder diesel as standard (530d, 535d) which is roomier and quieter than F31 4-cyl diesel. F11 commands £3,000-£5,000 used premium for the same age and mileage. Pick F31 for compact family; F11 for full family long-distance.
F30 or G20 3 Series?
Generational comparison. F30 (2012-2019) is the mature used buy at £8,500-£24,000 range. G20 (2019+) is the current generation at £18,000-£40,000+. G20 has modern infotainment, 48V mild-hybrid, ULEZ from launch. Pick F30 for budget; G20 for modern.
Why is the F31 boot only 15 litres bigger seats up?
BMW prioritised similar saloon-vs-Touring proportions over maximum cargo. The 15-litre difference is the floor area only; the FOLD difference is huge (1,170 L saloon vs 1,500 L Touring). Touring wins on max load, not on day-to-day. The headline 'practical Touring' is genuine but more so for max loading than for routine groceries.
How much does F31 Touring cost to run vs F30 saloon?
Within £100/year of each other. Same engines, same servicing, same insurance. Only meaningful difference: F31 air suspension service over the long term adds around £100-£200/year averaged across the ownership life. Otherwise identical.
F31 or X3 (F25) for family use?
F25 X3 has higher seating position, larger interior volume (especially headroom), and the 4WD option. F31 Touring has lower running cost, better fuel economy, and saloon-like driving feel. Same buyer's choice as BMW estate vs SUV across the lineup. £2,000-£4,000 difference in used prices favouring F31 Touring.
