If you spend a lot of your driving time on the motorway, what are the best cars to do it in? We've rated the 10 best diesel and petrol cars for covering those motorway miles.
Diesel cars might be getting a lot of bad press right now, but they still rule the roost when it comes to motorway driving, with many offering long distance economy coupled with comfort and refinement.
The best hybrid cars may be cleaner in the city, but if you’re covering more than 15,000 miles a year and most of them are on the motorway, a diesel is still the way to keep running costs down.
However, modern petrols can combine a balance of performance and economy that makes them genuine alternatives. With unleaded costing less at the pumps and no worries about DPF problems, petrols still hold an appeal, even for long-distance drivers.

Best cars for motorway driving in 2025
1. Mercedes-Benz E-Class
Year launched: 2016

2024 saw the arrival of an all-new Mercedes E-Class, but for regular motorway drivers, there's still plenty going for the previous model that ran from 2016 to 2023. If you want a refined and classy motorway car, we can think of few better than the high quality E-Class. A car designed for covering vast autobahn distances in serene comfort, it has a superbly comfortable interior, excellent ride quality and feels reassuringly Teutonic from behind the wheel.
There’s a wide range of engines available, but the E220 d is our choice for covering motorway miles effortlessly. You’ll see close to 51mpg in real-world driving, a figure that would be impressive even if the engine clattered like the generator at a budget campsite. But it doesn’t. In fact, not only is the E220 d incredibly quiet at speed, it’s actually quite pacey and extremely composed.
This is a board-level car with factory floor running costs. It’s also well equipped and all models come with navigation, climate control, Bluetooth, LED headlights, radar cruise control and Mercedes Artico fake leather (but actually very good) upholstery.
2. BMW 3 Series
Year launched: 2019

Whereas once upon a time the ubiquitous car you’d see on every street corner and in every supermarket car park was likely a Ford Mondeo (or Ford Sierra/Cortina depending on your age...) the modern-day equivalent is the BMW 3 Series.
Yet despite selling in huge numbers, particularly here in the UK, the 3 Series' appeal hasn’t been dented by its popularity. Indeed, it continues to sell like garlic-flavoured crosses at a vampire hunters weekend retreat.
The latest BMW 3 Series makes a strong claim to the title of ‘all the car you’ll ever need’, it’s that good. BMW hasn’t done anything revolutionary with the latest version, but has refined the formula that made the previous 3 Series so good. The 318d and 320d are the best choices for motorway driving, and you can expect to average around 52mpg. You can also add four-wheel drive with an xDrive model.
3. Jaguar XF
Year launched: 2015

The Jaguar XF is somewhat long-in-the-tooth these days, but that doesn't stop it from being a fabulous motorway car. Jaguar's engineers have an uncanny knack of building cars that ride incredibly smoothly, and yet also corner with agility and poise, so in truth, the XF is a car that excels on any kind of road.
And while many car makers continue to shun diesel, Jaguar still offered the XF - available in both saloon and 'Sportbrake' estate forms - with diesel power right up to its demise in 2024. The D200 is a 2.0-litre four-cylinder engine that produces a muscular 204PS, yet also returns an official WLTP fuel economy figure of up to 56.8mpg. A silky-smooth eight-speed automatic gearbox makes the car even more relaxed.
4. Skoda Superb
Year launched: 2015

Again, 2024 has seen the arrival of a new Superb, but buying the previous one as a used car could save you a heck of a lot of money. Understated, bordering on anonymous it may be, but the Skoda Superb remains a car that offers what few other rivals can: vast reserves of comfort and space. The Superb may not be the most dynamic of models, but it’s supremely cosseting, making it an ideal long-distance car.
It may not have a BMW badge on the bonnet, but no BMW this size can offer the amount of space in the back the Superb can. In fact, nothing this side of an Mercedes S-Class matches the Skoda Superb for rear seat space. There’s acres of legroom for those in the back even with both front seats moved all the way back.
The 1.6 TDI Greenline will average more than 60mpg, making it incredibly cheap to run, but we’d suggest going for the 2.0 TDI 150, which will still do more than 55mpg but has a lot more get up and go when needed. The Superb is available with petrol power, too. The 2.0 TSI is great but thirsty, so we’d go for the 1.5 TSI, which works surprisingly well.
5. Ford Focus
Year launched: 2018

The Ford Focus may not be the sales juggernaut it once was due to the popularity if SUVs, but it proves you don't need to go executive or expensive to have a wonderful long distance driving experience. Of course, the Focus has made a career out of being all things to all drivers, from slapping on the L-plates to high performance nirvana.
For piling on the miles, you could easily and happily get by with the 1.0-litre petrol motor, while the 1.5 Ecoboost petrol is a great choice for this sort of use. However, our money would go on the 1.5-litre turbodiesel for its unerring smoothness and ability to return impressive fuel consumption.
Another reason for choosing the Ford Focus is its ride comfort. Noted for its handling prowess, the Focus is also one of the best at absorbing lump-strewn surfaces to leave its occupants unflustered and fresh at the end of a long day's journey. Plus, there's an array of trim levels to pick from to tailor the Focus to your desires and budget.
6. Volvo V60
Year launched: 2018

Volvo was made famous by its estate cars - rightly so because it has built some of the best - but the Swedish firm has largely turned its back on the humble wagon to concentrate more on SUVs. However, you can still get a brilliant Volvo estate car. It’s a toss up here between the excellent Volvo V90 and the smaller V60, but we’re plumping for the latter due its cheaper price tag and better economy. The V60 may not have the boot space of the V90, but it echoes its bigger sibling in crucial areas such as comfort and refinement.
Like its larger counterpart, the V60 has some of the best seats around. Volvo has long been renowned for having brilliant chairs, which is no surprise when you learn that Volvo works with orthopaedic surgeons to design them. It means that even after long stretches at the wheel, you won’t get out full of aches and pains.
The D3 manual model is the most economical in the range and 54mpg should be achievable in real-world driving. It’s a 2.0-litre four-cylinder diesel with 150PS, but pulls strongly and never feels like the poor relation to the D4. However, you will have to look to the used market for this as all of the new V60s come as mild or plug-in petrol hybrids.
7. Citroen C5 Aircross
Year launched: 2019

Think ride quality, and traditionally, you'd think Citroen. The French brand may have changed a lot over the years but it has never lost its knack of making cars that ride well. That tradition is certainly alive and well in the C5 Aircross. For our money, this is the best-riding crossover or SUV (call them what you will) of its type, though Citroen has an all-new C5 Aircross for 2025.
It may not have the handling prowess of others - we’d say the Peugeot 3008 and SEAT Ateca are much better in corners - but the C5 Aircross trades that in place of a serene and extremely forgiving ride. That makes this the perfect choice of crossover for motorway driving.
The most economical model is the 1.5 BlueHDi 130, which may not be a ball of fire, but will happily return 50mpg all day long. The C5 Aircross also comes with Citroen’s excellent 1.2 Puretech petrol engine that delivers far more performance than its size would suggest, with respectable fuel economy in the mid-30s.
8. Audi A6
Year launched: 2018

Few cars can match the2018 to 2025 generation of Audi A6 for its clever tech. This thing has so many systems that we could fill a page explaining what all the different abbreviations and initialisms mean. Audi says it has 39 driver assistance functions, from clever adaptive cruise control, which slows down and accelerates using data from the navigation, to parking pilot, which lets you stand outside the vehicle while it parks itself.
But perhaps the A6’s best feature is its interior. It’s a lovely place in which to spend hours and hours, which is brilliant for those long motorway slogs.
While the 50 TDI, with its 3.0-litre V6 diesel engine, may be appealing on paper, we’d avoid it. Not only is it going to be expensive, but its gearbox is frustrating and the car feels noticeably heavier than the four-cylinder diesel. The 40 TDI is actually the better choice, and is also more economical: expect to see 49mpg.
If you're after a petrol, check out the 40 TFSI as it's a real gem. It may only be a 2.0-litre four-cylinder, but with 250PS, it has plenty of power in reserve for effortless performance when needed.
9. Kia Ceed Sportswagon
Year launched: 2018

The estate version of the Kia Ceed may seem like it stands out like a sore thumb alongside the likes of the Mercedes E-Class, but there’s a good reason the Ceed Sportswagon makes an appearance here: fuel economy. The 1.6 CRDi version is incredibly frugal, and you can expect to see a genuine 60mpg without having to drive as if you’re on a milk round.
There’s more to the Ceed than just an economical diesel engine if you dig a little deeper. The latest Ceed shows Kia at its best. There may be those who still dismiss Kia as a budget make, but sit them in the Ceed for a few minutes and they will quickly change their mind. The quality inside is top-notch, with a finish to match.
True, it’s hardly a barrel of laughs to drive - the Ceed majors on comfort and reassurance rather than fun - but its quality and ability will undoubtedly surprise you.
10. Volkswagen Tiguan
Year launched: 2024

Volkswagen has purged diesel engines from most of its model ranges these days - not really surprising given the German company could be accused of starting the backlash against diesel in the first place - but the latest Volkswagen Tiguan is one of the firm's few cars where diesel remains an option.
Where once a broad range of diesel. engines would have been offered, there's now only one, a 2.0-litre unit with 150PS. This gives official WLPTP fuel economy of 52.2mpg, so expect 45mpg in the real world, not bad for a family SUV of this size.
And a cracking family SUV it is, too. The interior is smartly trimmed and has lots of passenger space, while the huge boot adds to the Tiguan's practicality. There's lots of equipment provided as standard, while the driving experience is confident, assured and refined.
Ride comfort and refinement are key: you don't want to spend hours at the wheel being jittered about or deafened by exterior noise. A good driving position and good visibility help, too, while good fuel economy will help reduced the cost of long motorway schleps. It might not be a popular choice anymore, but diesel cars offer the best fuel economy on long journeys.
That depends on your needs. As an all-rounder, the Mercedes E-Class is hard to beat thanks to its plush ride, posh cabin and strong refinement, but if you have a smaller budget, the Kia Ceed Sportwagon has many of the same attributes for less cash.
Hybrids are at their best around town where they can make the most of their regenerative braking and electric-only running. On the motorway, a hybrid's battery quickly becomes depleted, so the petrol engine is needed to drive the car, and it has to work even harder to haul around the extra weight of the battery and motor. That means hybrids are often thirstier on the motorway than petrol or diesel equivalents.
