The Honda N-Box Custom Turbo is a tall, small hatchback made in Japan with a 658cc engine. A small engine means low road tax, but the COE costs the same as for a bigger car. This guide sets out the costs the facts let us show.
The insurance figures are examples, as of 1 November 2026. They are for one stated driver and one car age. Your own premium depends on your details.
On the new-car list
The new-car list read on 2026-10-10 shows one version. It is listed as a hatchback, made in Japan.
- Honda N-Box Custom Turbo: petrol, 658cc, 63bhp
The price page prices the same version. It is the one most of the insurers quote.
The listed price
As listed on 2026-10-10, the N-Box Custom Turbo cost S$183,000, including COE as listed that day.
A large share of that is the COE, which does not shrink with engine size. Dealer prices move after each COE round, so ask for a current figure. Check what each offer includes before you compare.
COE for a 658cc car
Every car here needs a COE. The price page says the N-Box Custom Turbo, with its 658cc engine, needs a Category A COE if its power is 97kW (130bhp) or less. If its power is more, it needs a Category B COE.
In the October 2026 2nd round, Category A closed at S$132,004 and Category B at S$131,901. The COE page shows the latest results.
Road tax: very low
LTA's formula sets road tax by engine size. For 658cc, it is S$324.14 a year before any age surcharge. Few petrol cars pay less.
An age surcharge applies once the car passes 10 years:
- 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 any age.
Insurance for the standard driver
The Honda N-Box price page prices this profile:
- Car: N-Box Custom Turbo, registered 3 years ago, private use, comprehensive cover
- Driver: aged 40, married, office job, 10 years of driving
- Record: 50% NCD, no claims
- Repairs: authorised workshop, no options
8 insurers price it. The lowest premium is S$654.92 a year. The insurer whose lowest plan costs most asks at least S$1,036.63. That is S$381.71 more, or 58% on top. All prices include 9% GST.
Many of the plans sit close together, between the lowest figure and S$883.35. 11 insurers have no online price for this model.
A low premium with a low excess
On this page, the lowest premium carries a S$500 excess, at the low end of the range. Most plans carry S$600. One plan carries S$2,500.
So here you do not trade a low premium for a high excess. Even so, read each plan. One low-priced plan covers collision only, and several prices are marked as estimates.
What moves the premium
The price page shows the lowest price with one change at a time:
- No NCD (0%): S$1,455.37, up S$800.45
- 20% NCD: S$1,164.29, up S$509.37
- Driver aged 27, 3 years' driving, 30% NCD: S$1,296.87, up S$641.95, from 6 insurers
- Driver aged 65, 20 years' driving, 50% NCD: S$701.96, up S$47.04
- New car, registered this year: S$565.01, down S$89.91, from 7 insurers
- Car 8 years old: S$700.05, up S$45.13
For this car, losing your NCD is the costliest change. The lowest price rises by 122%. That is more than the young driver profile adds.
Car age works the other way from many cars. A new N-Box is cheaper to insure than the 3-year-old car on the page. An 8-year-old one costs more.
The older driver pays only a little more. These are lowest prices only, and other plans may move by different amounts.
Against other small cars
The price page sets the N-Box beside six cars with engines of a similar size, for the same driver and car age:
- Mitsubishi i: S$799.43
- Subaru R1 i: S$735.71
- Subaru R2: S$735.71
- Suzuki Alto: S$657.42
- Suzuki Hustler: S$657.42
- Perodua Kancil: S$637.65
Their average lowest price is S$703.89. The N-Box is 7% below that. One of the six, the Kancil, is cheaper to insure on these details, and only 2 insurers price that car.
The N-Box also draws more insurers than most of its peers. Other Honda models are on the Honda car insurance page.
The costs that depend on you
These have no single figure:
- Parking: season parking at your HDB block or condo, plus parking out.
- Petrol: set by distance and pump prices.
- ERP: set by your routes and timing.
- Servicing: follow the maker's schedule, and ask what the warranty covers and for how long.
- Depreciation: what the car loses over its COE life, from what you pay to what it later fetches.
