Fancy a premium saloon but are struggling to see the difference between a used Mercedes C-Class vs. used Mercedes CLA?
Beyond obvious differences in size and styling, there are some under-the-bonnet factors to consider that could make a huge difference in terms of everyday experience.
Below, we outline some considerable differences to help you decide whether a CLA or a C-Class is best for you.
Mercedes C-Class vs. Mercedes CLA: which has more style?
)
The Mercedes C-Class has a classic and refined look typical of a bigger and more expensive car, helping to give it a luxurious edge for a slightly lower price point than something like a Mercedes E-Class.
It has a sporty silhouette and has a softer and more curvy approach than a similarly-sized BMW 3 Series, while still maintaining the traditional three-box saloon bodyshape.
The Mercedes CLA is a similar shape, but it’s based on the smaller A-Class, so has smaller proportions overall.
It’s also a little bit sportier – think of a coupé, but with the convenience of rear doors as well. This gives it a sleek appearance, but it also helps with aerodynamics (and efficiency).
Overall, the CLA looks sportier and more aggressive than the C-Class, but they both have stacks of premium appeal.
What is it like to drive a Mercedes CLA vs. C-Class?
)
Although they look reasonably similar, there’s a really important difference in the way they drive.
The Mercedes C-Class is designed to be a driver’s car through and through. It’s rear-wheel-drive, which is typically a more engaging setup, giving the car a feeling of being powerfully pushed through corners.
Like the A-Class on which it’s based, the CLA is front-wheel-drive. This is better for efficiency to a certain degree, but it’s more suited to a sedate driving manner. It’s an excellent pick for cruising around town.
The CLA is also available with smaller engines, which are still punchy enough, including an excellent 1.3-litre petrol that actually comes from Renault.
You’ll find a selection of larger engines in the C-Class, helping to give it more oomph and solidifying its position as an excellent long-distance cruiser.
Both are available with (different) plug-in hybrid setups that are surprisingly nippy and open the door to rock-bottom running costs if you have access to a home charger.
Newer Mercedes C-Class hybrids can do well over 60 miles on electric power alone in the right conditions, giving them one of the best electric-only ranges of any PHEV. Energy is stored in a large 25kWh battery – twice the size of many other plug-in hybrids.
Mercedes C-Class vs. CLA interior and technology
)
Both the Mercedes C-Class and CLA offer luxurious interiors and cutting-edge technology, reflecting the German manufacturer’s commitment to building some of the most premium cars you can buy.
The CLA has a sleek and modern cabin with a focus on a sporty aesthetic. Proportions are a little more compact compared with the C-Class, but it doesn’t feel cramped.
Inside the C-Class, you’ll find a more open and airy environment dominated by a more wraparound-style cockpit.
Newer versions come with a slick centre console comprising a large infotainment display and a few physical controls, but even older models get an impressive system as standard.
If you like your car tech, you’ll want to find a second-generation post-2019 CLA or a fifth-generation 2021-onward C-Class. They have the latest MBUX infotainment systems that are among the best in the business.
Shoulder room in the back of the CLA can make long trips for three adults side-by-side a little uncomfortable, while a transmission tunnel running down the centre of the C-Class (just like many of its rivals) has an impact on leg room, especially for the middle-seat occupant.
Neither car could be described as short on space, but these are just some things to consider if you regularly carry a few adults or taller teenagers.
Mercedes CLA vs. C-Class dimensions
)
The Mercedes CLA is a reasonably long car – at 4,688mm long, it’s about 26cm longer than the A-Class hatchback.
Fortunately, though, it’s equally as manageable in tight car parks, where its 1,999mm width (including mirrors) comes into play. It’s also 1,427mm tall.
The C-Class is longer still, at 4,793mm, which is about the same as other saloons including the Tesla Model 3.
It’s slightly wider (2,033mm, including mirrors) and taller (1,446mm) than the CLA, too.
With a 460-litre boot, the CLA could actually be more practical than you think despite its coupé-like design. Plug-in hybrid models have a smaller 395-litre space to accommodate the extra batteries.
The C-Class has slightly more space, measuring 490 litres, but the latest PHEV models have a smaller 360-litre boot. Remember, though, that the battery in the latest C-Class is nearly twice the size of that in the latest CLA.
CLA vs. C-Class: which is more reliable?
Mercedes is known for its robust engineering and quality craftsmanship. Because the C-Class is a staple in the company lineup, it’s considered highly dependable and comes with plenty of quality touches.
The brand as a whole generally reports average results in consumer feedback surveys, and the warranty on offer is also industry-average – three years.
Both cars are just as reliable, but it’s worth noting that the C-Class’s more complex rear-wheel-drive setup could see some specific repair bills end up being higher.
Used Mercedes C-Class vs. used Mercedes CLA: which should I buy?
For a comfortable cruiser that has plenty of space and an engaging driving feel, the C-Class makes for a great pick. It sells well new and used to a variety of buyers, including families and company car drivers.
If you’re after something smaller and more affordable to run, the CLA doesn’t skimp on quality or technology.
