A BMW M4 Convertible is a four-seat soft-top with a 3.0 petrol engine. It sits at the top end of what people insure in Singapore. If you are pricing one, here are the costs we can put numbers to, from COE to insurance.
The insurance figures are examples for one stated driver, as of 1 November 2026. Your own quote will depend on your record and details.
The version listed
On 2026-10-10, the new-car list showed one version: the M4 Convertible 3.0 Competition M xDrive. It is petrol, 2,993cc, 523bhp. The body type is listed as Sports, made in Germany.
The quote form prices the same Competition M xDrive. That is the version most insurers quote.
What it was listed at
As listed on 2026-10-10, it was S$665,888, with COE included. COE rounds and dealer terms move that figure. Ask for the breakdown of any offer so you can see what is in it. Items such as servicing packages, accessories and registration fees can sit inside or outside a quoted price. Two offers that look close may differ once you line these up.
Which COE category
With a 2,993cc engine, above 1,600cc, the M4 Convertible needs a Category B COE. The price page gives S$131,901 for the October 2026, 2nd round. See the COE page for later rounds.
Road tax each year
Road tax follows engine size. For 2,993cc, LTA's formula gives S$2,376.88 a year, before any age surcharge.
Past 10 years, the surcharge applies:
- Over 10 years: +10%
- Over 11 years: +20%
- Over 12 years: +30%
- Over 13 years: +40%
- Over 14 years: +50%
The road tax page works out other cars.
Insurance for the page's standard driver
The BMW M4 Convertible price page uses these details:
- Car: M4 Convertible 3.0 Competition M xDrive, 3 years old, private use, comprehensive
- Driver: aged 40, married, office job, 10 years' driving
- Record: 50% NCD, no claims
- Repairs: authorised workshop, no options
2 insurers price it, across three plans. The lowest premium is S$1,461.89 a year. The other insurer's price is S$3,556.74, S$2,094.85 more, or 143% on top. That one is marked as an estimate. All prices include 9% GST.
The first insurer also has a second plan at S$1,978.51. So two of the three plans sit fairly close together.
Seventeen insurers have no online price for this car. A soft-top sports car may be priced case by case, so a quote on your own details is the way to widen the field.
The excess you would pay
The two lower premiums carry a S$500 excess. The estimate carries S$2,000. Here the lower premiums also come with the smaller excess. Even so, check the plan terms, since cover can differ beyond the headline numbers.
Changes that move the premium
The page shows the lowest price after one change:
- No NCD (0%): S$3,248.64, which is S$1,786.75 more
- 20% NCD: S$2,598.91, S$1,137.02 more
- Driver aged 27, 3 years' driving, 30% NCD: S$3,287.19, S$1,825.30 more
- Driver aged 65, 20 years' driving: S$1,616.20, S$154.31 more
- New car, registered this year: S$1,497.08, S$35.19 more
- Car 8 years old: S$1,464.04, S$2.15 more
The younger driver costs most, 125% above the standard figure. Losing all NCD is almost as costly. That makes your NCD worth guarding.
Car age barely moves the lowest price. A new car and an 8-year-old car land within a few dollars of the standard case. All cases keep 2 insurers pricing. These are lowest prices only. The estimated plan may move by a different amount, and so may the second plan from the lower-priced insurer. If your age, NCD or claims differ from these cases, ask for a quote on your own details.
Similar 3.0-litre cars
The price page compares six cars of a similar engine size, 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 M4 Convertible costs 3% less than that average. But 4 of the 6 are cheaper to insure. The average leans high because of one car that only 2 insurers price. More BMW models are on the BMW car insurance page.
Costs that vary by owner
No single figure covers these:
- Petrol: a 3.0 engine, your distance and pump prices.
- Parking: covered season parking may matter more for a soft-top. Costs depend on where you live and work.
- ERP: your routes and travel times.
- Upkeep: the roof, tyres and brakes all need care over time. Follow the maker's schedule and check the warranty.
- Depreciation: what you pay now against the resale value later.
