Hi Francis,

It’s actually pretty brilliant — that 1.6 iDTEC engine is one of the best diesels we’ve ever sat behind. It’s smooth, has plenty of performance and is very economical. Plus, Honda engines were never implicated in any diesel emissions cheating, so your conscience can remain untroubled. The rest of the car is rather lovely too. Honda’s quality is a given and that generation of Civic is both massively roomy and massively versatile with those clever flip-up ‘Magic’ rear seats. It’s also good to drive — not as agile as a Ford Focus, but solid and planted, with nice steering feel and good comfort levels, too. The only demerits are a bit too much road noise and a slightly messy dashboard layout.

Hi David,

Well, regular (as in non-PSV) car tax is worked out on the CO₂ emissions. As yours is a Superb 1.6 TDI Greenline, that has official CO₂ emissions of 114g/km, and so will cost you €200 a year to tax.

Hi Marlon,

It’s not a classic yet, I’m afraid. To qualify for ’vintage’ status (as Revenue erroneously insists on using), a car has to be at least 30 years old, so the youngest BMW Z3s won’t start to qualify until 2025. Calculating a VRT value for one is tricky, as prices and values are massively variable according to condition. I would think that a value of around €6,000 sounds about right, which could mean as much as €2,100 in VRT terms given that the 2.0i auto is in the highest band for VRT with CO₂ emissions above 225g/km. That’s just a guess though — Revenue is notoriously awkward about valuing cars that are less common.

Hi Mark,

The government knows the emissions of each vehicle simply because each vehicle is put through a series of official laboratory tests as part of the process of homologation — the legal process whereby a car is pronounced as passed for sale to the public - and that data is made available by the car manufacturers. As for which is cheaper to tax, it’s down to the CO₂ emissions and we’d have to know which make and models you’re looking at before we could give you a precise answer, but in most cases, for a given car, the diesel would have lower CO₂ emissions and hence motor tax.

Hi Tomas,

Well, the NOx tax isn’s about the size of the engine, it’s about the NOx emissions, which are not specifically related to the size. It could be worth getting on to the Japanese Ministry of Land, Infrastructure, Transport and Tourism, who may be able to provide you with a specific NOx figure for the car you’re talking about, but otherwise, just be thankful it’s not a diesel — those are subject to a maximum €4,850 extra in NOx tax if you can’t provide an accurate figure.

Hi Ed,

OK, this one takes a bit of deciphering. I’m guessing that you mean you own two Mercedes-Benz models, both using the 2.1-litre diesel four-cylinder engine. I’m also assuming that you’re talking about the cost of motor tax, although the €290 figure is a little odd — did you mis-type when you meant either €280 (for Band B2) or €390 (for Band C)?

The discrepancy could be down to a number of factors. You don’t, for example, state which models you’re talking about — E-Class? C-Class? Coupe? Convertible? Estate? Do both cars have automatic transmissions? Are they both on the same size wheels? Were they both manufactured in the same year? There’s a huge variation in vehicle emissions and, if you’re talking about the gap between Band C and Band D, it takes only a single g/km of CO₂ to tip from one to the other.

Hi Peter,

It depends on how the interior layout of the van is arranged. If there is no bulkhead or physical separation between the seating area and the cargo area, then it’ll be registered as a Category A vehicle and it’ll be taxed on the full CO₂ emissions. If, though, there is a fixed bulkhead or separation between the seats and the cargo, then it goes into Category B, as it’s allowed to have more than three seats but have the passenger and cargo/functional compartments in completely separate units. That should VRT is charged at a flat rate of 13.3 per cent of the OMSP.

Hi Michael,

The NOx emissions of that model are 70mg/km, so you’ll have to pay an additional €450 on top of the normal VRT charge if you’re importing one. 

Expert answer

Hi Veronica,

That car should (emphasis on the should) have NOx emissions of just 30mg/km so will cost just €150 extra on top of the normal VRT.

Hi Gerry,

In terms of tax there won’t be any changes before the Budget in October, and there are unlikely to be major changes then. There have been rumblings of a change in the diesel tax system, but the various departments are known to be hesitant to introduce a third motor tax regime on top of the two we already have. A general increase in the cost of motor tax, within the existing bands, is quite likely though, as the Government starts to push people towards electric motoring.

In terms of fuel costs, prices at the pump have spiked up in recent weeks thanks to the Trump-Iran standoff, and this week the average per-litre cost of diesel rose to €1.31. That is likely to continue to rise as long as tensions in the Middle East, and indeed in the White House, remain high.
