Hi Julie.

First up, you've not told us which engine your Kuga has, and that's a key detail. We'll have to assume it has one of the most common units, which is the 2.0 TDCi diesel.

Secondly, a "wet belt" is a type of timing belt. When someone says "timing belt" they generally mean a "dry" belt that does not run in oil - like a wet belt does.

Anyway, the 2.0-litre diesel engine in the 2015 Kuga has a dry timing belt, not a wet one. It also has a small timing chain in the cylinder head joining the camshafts.

Hi Fred,

We did find a CO₂ rating for that BMW on the Japanese Ministry of Land, Infrastructure, Transport and Tourism website (click here for the file) – it's 121g/km, but it's much harder to find NOx ratings on there and I've not been entirely successful either.

I did find this official PDF showing a NOx figure for the BMW 320d (0.063g/km), but it does not specifically mention “LDA-8C20”.

Hi Andrei,

As that Golf is over 30 years old, it will indeed only attract the flat-rate VRT of €200, and it won't be slapped with any NOx levy either.

Hi John,

I assume you mean the Tucson, but anyway, yeah, the 192 Hyundai 1.6 diesel engine has a timing belt.

Hi Bill,

Obviously a plug-in hybrid (PHEV) makes most sense here as those come with ultra-low CO₂ emissions to help keep the BIK down. Though we would only recommend you buy one if you have a way of charging it up at home or at work on a very regular basis.

If you like your Audi, then the new Audi A5 e-hybrid makes for a good option. It can be had as a Sportback or Avant estate within your budget and it's a really lovely car. The e-hybrid system allows for a long electric range and low emissions, too. Read our review of the A5 e-hybrid for more.

The BMW 330e is another excellent premium PHEV within budget, both as a saloon or Touring estate. It's not as fresh-faced as the Audi A5, but it's still a good car. Read our review of the updated BMW 330e if you're interested.

Our next port of call would have been the Skoda Superb, but for some bizarre reason it's only offered as a PHEV in Combi estate format, so if you don't want an estate, then it's not for you. If you're open to the idea, however, it's a considerably larger car than the BMW and Audi mentioned above, if not as interesting to drive. Within budget, however, is the range-topping L&K variant, which puts the Audi and BMW to shame in terms of what you get for your money. Again, read our review of the Skoda Superb Combi PHEV for more.

Other than that trio, you'll be looking at SUVs in reality, unless you fancy moving to a fully electric car.

Come back to us if you want help narrowing things down further.

Hi Elaine,

The BMW X3 diesel is what's called a "mild hybrid", so it can't be plugged in. The plug-in hybrid only makes sense if you can plug it in at home to charge up the battery at every available opportunity. If you don't do that then it's essentially the same as fuelling a heavy petrol-only model.

In general, a diesel car is more efficient than a plug-in hybrid when it comes to long journeys and it sounds like that's what may suit your needs better.

Hi Barry,

Assuming you might like to use the rear seats, the BYD is the least spacious option of the three as its boot is much smaller. It holds up to 425 litres with its rear seat in place, while the Santa Fe PHEV manages 621 litres in five-seat mode (it's a seven-seater in which you can easily fold down the third row of seats).

The Kodiaq PHEV (assuming you're only looking at the plug-in-hybrid versions of each car mentioned) is a strict five-seater, but it comes with the largest space behind at 725 litres. If can be had in seven-seat guise with a simple petrol or diesel engine if you need the flexibility of the interior.

One major extra bonus of the Santa Fe is that its tailgate reveals the widest opening of the three, though really, the Skoda is likely to fit the bill as well. Their load sill heights are about the same distance from the ground at in and around 760mm.

Hi Keith,

Neither I'm afraid. It will go by the engine size, as things for cars used to be before 2008. That's the case for privately taxing a commercial vehicle of any age, incidentally, aside from actual vintage commercials that is.

Expert answer

Hi James,

You're not alone in having this issue. We can find that T-Roc on the MLIT website and get its CO₂ emissions and fuel consumption data, but we cannot see a document showing its NOx rating. The best we could come up with is a spec sheet for the 2025 model on sale today in Japan. Given that this should be the same as the 2022 version, Revenue may accept that. It's 150mg/km.

We've not heard of anyone successfully obtaining this information from a European brand directly, and it's unlikely that Revenue would accept data for the T-Roc sold in a country other than Japan, as there can be regional differences.

Hi Anais,

All diesel engines available in the 2014 Avensis used timing chains.
