The Audi Roadjet Concept is a rare name on Singapore roads. If you own one, or are weighing one up, this guide sets out what it costs to keep each year. It covers the COE rule, road tax and car insurance, one cost at a time.
The insurance figures are examples for one stated driver, as of 1 November 2026. They show where prices sit. Your own quote turns on your own details.
What the records show for this car
The new-car list has no entry for the Roadjet Concept on sale now. So there is no list price, power figure or body type to give here.
What the price page does show is the version insurers quote. That is the Audi Roadjet Concept with a 3,123cc engine. The quote form lists only this one version. Every figure below is for it.
COE: which category applies
Each car on the road in Singapore runs on a Certificate of Entitlement. The price page puts the Roadjet Concept in Category B, because its 3,123cc engine is above 1,600cc.
In the October 2026 2nd round, Category B closed at S$131,901. That figure matters if you are registering a car, or weighing what a COE renewal might involve. Premiums move every round. The COE page carries the latest results.
Road tax on a 3,123cc engine
Road tax follows engine size. A bigger engine pays more, and the scale climbs faster as engines grow.
For this engine, LTA's formula gives S$2,577.48 a year, before any age surcharge. That is a large yearly bill for road tax alone.
Older cars pay more on top, once they pass 10 years:
- Over 10 years: +10%
- Over 11 years: +20%
- Over 12 years: +30%
- Over 13 years: +40%
- Over 14 years: +50%
A concept-badged car that has been around a while may well sit in one of these bands. Check the registration date before you budget. The road tax page works out other engine sizes.
Insuring it: one insurer, one price
The Audi Roadjet Concept price page prices one standard set of details:
- Car: registered 3 years ago, private use, comprehensive cover
- Driver: aged 40, married, office job, 10 years' driving
- Record: 50% no-claim discount (NCD), no claims
- Repairs: at an authorised workshop, no options added
On those details, just 1 insurer gives an online price. It is S$1,524.39 a year, including 9% GST. The plan carries an excess of S$1,200.
The page lists 18 other insurers with no online price for this model. Of the 19 on the panel, that leaves you almost nothing to compare online. For a rare car, that is common. It also means the one price shown is not a market spread. It is a single figure.
What the excess means here
The excess is the part of each claim you pay yourself. S$1,200 is a real sum to find after an accident. When you look at any quote for this car, set the excess beside the premium.
How the price moves with the driver and the car
The price page changes one detail at a time and shows the new lowest price:
- No NCD (0%): S$3,506.08, which is S$1,981.69 more
- 20% NCD: S$2,560.98, S$1,036.59 more
- Driver aged 27, 3 years' driving, 30% NCD: S$3,829.98, S$2,305.59 more
- Driver aged 65, 20 years' driving: no online price at all
- A new car, registered this year: S$1,621.66, S$97.27 more
- A car 8 years old: S$1,491.93, S$32.46 less
The younger driver is the costliest change, at 151% more than the standard price. Losing the NCD comes close behind. The car's own age matters far less. An 8-year-old car is only a little cheaper to insure.
The missing price for an older driver is worth noting. If the main driver is 65 or so, there may be no online quote to compare. You may need to ask for one directly.
Set against similar cars
The price page lines the Roadjet Concept up with six cars of a similar engine size, for the same driver and car age:
- Alfa Romeo 166: S$2,897.48
- BMW 640i Gran Coupe: S$1,312.28
- BMW 730d: S$1,115.28
- BMW 440i Gran Coupe M Sport: S$1,061.44
- BMW 730i: S$943.53
- BMW 7 Series: S$925.04
Their average lowest price is S$1,375.84. The Roadjet Concept costs 11% more than that. Five of the six are cheaper to insure. Only the Alfa Romeo 166 costs more.
Several of these rivals also draw far more insurers. The BMW 730i, for one, has 14 pricing it. More insurers usually means more choice of plan and excess. Other Audi models are on the Audi car insurance page.
Costs that depend on you
Some costs vary too much from owner to owner for one figure to fit.
- Parking: season parking at home, plus parking at work and when you go out.
- Petrol: set by how far you drive and pump prices. A large engine tends to use more, but your own driving decides it.
- ERP: depends on your routes and the time of day.
- Servicing and parts: a rare model can mean parts take longer to find. Ask about parts supply before you commit.
- COE life and value: what the car is worth turns on how much COE it has left and what buyers will pay.
