The BMW M340i is a 3.0 petrol sedan. It is not on the new-car list now, so most buyers will be looking at a used car. This guide covers the costs that follow it each year: road tax and car insurance, plus what the COE rule says.
Insurance figures are examples for one stated driver, as of 1 November 2026. Treat them as a guide to the market, not as your price.
Not on the current list
The new-car list has no entry for the M340i on sale now. So there is no list price to show here. If you are looking at a used M340i, the asking price, the COE left on it and its age all set what you pay.
Our quote form prices the M340i 3.0 xDrive with a 2,998cc engine. That is the version most insurers quote, and the figures below are for it.
COE for a 2,998cc car
The price page sets out the category. With a 2,998cc engine, above 1,600cc, the M340i needs a Category B COE. In the October 2026, 2nd round, Category B closed at S$131,901.
On a used car, the COE is already paid, and its remaining life is part of the asking price. If you renew the COE later, the rule above applies. The COE page shows the latest results.
Road tax
For a 2,998cc engine, LTA's formula gives S$2,382.76 a year, before any age surcharge. An older used car may already be close to the surcharge.
The surcharge starts once the car is more than 10 years old:
- Over 10 years: +10%
- Over 11 years: +20%
- Over 12 years: +30%
- Over 13 years: +40%
- Over 14 years: +50%
Check the car's registration date. The road tax page works out the sum.
A costly car to insure on this profile
The BMW M340i price page prices these details:
- Car: M340i 3.0 xDrive, registered 3 years ago, private use, comprehensive cover
- Driver: aged 40, married, office job, 10 years' driving
- Record: 50% NCD, no claims
- Repairs: authorised workshop, no options
2 insurers price it, across four plans. The lowest premium is S$4,901.23 a year. The other insurer starts at S$5,623.55, which is S$722.32 more, or 15% on top. Its plans go up to S$7,851.80. All include 9% GST.
Those are high figures for a driver with 50% NCD. Fifteen insurers have no online price for the M340i, so the online field is very thin. A quote on your own details may turn up other prices. It is also worth checking the price page again later, as insurers add models over time.
The excess trade-off
The lowest premium carries a S$2,500 excess. The other insurer's three plans each carry S$300. So the lower premium asks much more of you if you claim. Weigh the S$722.32 premium gap against the excess gap.
How the lowest price moves
The page shows the lowest price after one change:
- No NCD (0%): S$9,212.83, which is S$4,311.60 more
- 20% NCD: S$7,460.30, S$2,559.07 more
- Driver aged 27, 3 years' driving, 30% NCD: S$9,633.09, S$4,731.86 more
- Driver aged 65, 20 years' driving: S$5,257.16, S$355.93 more
- New car, registered this year: S$6,114.00, S$1,212.77 more
- Car 8 years old: S$2,221.88, S$2,679.35 less, with 3 insurers pricing
Two points stand out. The younger driver nearly doubles the lowest price, up 97%. And car age matters a great deal on this page.
An 8-year-old car comes in at less than half the standard figure, with one more insurer pricing it. A new car costs more than the standard case. If you are weighing a used M340i, that pattern is worth knowing. As before, these are lowest prices only.
Six 3.0-litre cars for comparison
The price page puts the M340i beside six cars with engines of about 3.0 litres, for the same driver and car age:
- Alfa Romeo 166: S$2,897.48
- Audi Roadjet Concept: S$1,524.39
- Audi Q8: S$1,323.18
- Audi S4 Saloon: S$1,209.34
- Audi A8: S$1,092.69
- Audi Q7: S$1,002.60
Their average lowest price is S$1,508.28. The M340i costs 225% more, and all 6 are cheaper to insure on these details. Several of those cars have 8 or more insurers pricing them. The BMW car insurance page lists other BMW models.
Costs to budget yourself
These vary by owner:
- Petrol: a 3.0 engine, your mileage and pump prices.
- Parking: season parking at home and at work.
- ERP: your routes and times.
- Servicing and repairs: a used car's history matters. Ask for service records and check any remaining warranty.
- Depreciation: on a used car, it turns on the price paid and the COE years left.
Summary of yearly costs we can show
