Mazda 6 (Diesel) Review

4.5 Star review of the Mazda 6 (Diesel) Review


Value, overall composure, great driving dynamics, strong driveline performance, excellent build quality, good practicality, full-sized spare tyre (not a space saver)


Diesel engine not available with auto transmission, Mazda can’t match the South Koreans on warranty or equipment levels

The Mazda6 diesel is a strong performer with tremendous economy, great cruising range between refills and still manages to be quite refined – there’s not even a hint of ‘Massey-Fergusson’ about it. Unfortunately, the superb diesel engine is not available with an auto transmission, and you can’t have a diesel sedan either.

These constraints choke the uptake of diesel Mazda6's out there in the real world, and they mean most buyers cross the diesel off the list almost straight away and go for the petrol. If that’s you, check out our Mazda6 petrol review.

If you can stomach the thought of changing gears for yourself, however, and you don’t need a sedan, that diesel really is worth a second look – if only because it represents a tremendous performance upgrade over the petrol models.

The Mazda6 is quiet and comfortable – even the wagon refuses to be ‘boomy’, like the wagons you probably remember riding around in as a kid. Mazda has done a great job getting the Mazda6’s fundamentals right, and it’s a car you can drive comfortable between home and work every day – as well as between capital cities. In the diesel, that last point is important, seeing as there are plenty of capital cities you could hypothetically drive between – without stopping once, even for fuel.

However, just because it’s possible, and just because you can, it’s still probably a much better idea to take regular rest breaks.

Performance & Economy

The 2.2-litre common rail diesel four produces its peak power of 132 kW at 3500 rpm – that’s a slight (six per cent) power increase over the petrol, but because that peak occurs 2500 rpm earlier than in the petrol engine, it’s much more accessible.

The big story is torque: 400 Nm from 1000 rpm to 3000 rpm makes the 2.5-litre petrol engine’s 226 Nm at 4000 rpm look (and feel) anorexic. That’s 77 per cent more torque at, essentially, a quarter of the revs. Because power is basically a product of torque and revs, that diesel engine is a low-rpm powerhouse, and that means it’s a strong performer in real-world driving.

The other big news is economy: because diesels use much higher compression (the petrol uses 9.7:1 whereas the diesel employs 16.3:1) the mixture expands over a much greater range during combustion, and the result is outstanding efficiency. The official combined-cycle fuel consumption is 5.9 litres per 100 km, so with a 64-litre tank you’re looking at a theoretical cruising range in the 1000km-plus ballpark. And that’s music to your ears if you plan on doing any significant interstate driving.

Certainly you pay about $2000 more for the diesel – but just considering the additional performance alone it’s a very worthwhile investment.

Ride & Handling

The Mazda6 is a very well-built car – something of a Japanese forte generally, and something of a Mazda forte specifically. What that means is you typically don’t get rattles, squeaks and shakes even on rough roads because the underlying platform is very rigid.

This also gives rise to predictable, progressive cornering performance, as well as good ride quality. Basically, the more rigid the bodyshell, the more easily tunable the suspension, and the less the chance of secondary feedback making the body behave in undesirable ways when you go hard into a corner.

Mazda has done a great job getting the Mazda6 right, and the engineers have obviously tweaked it nicely in the middle of its model lifecycle because it’s even better today that it was when initially launched.

The Mazda6 diesel isn’t perfect – far from it. The absence of an auto transmission might not be a major impediment to sales in Europe, where the world and its brother drives diesel manuals, but it’s a serious speed hump here. If you’re in the market for a mid-size diesel and you must have an auto, it’s probably time to forget about the Mazda6 diesel and check out the Hyundai i40 instead, which is another strong diesel supplementing a range where the petrol is barely adequate. Alternatively, you could try on any one of several small diesel SUVs – including Mazda’s own CX-5 diesel and Volkswagen’s Tiguan.
