If you’re in the market for a premium compact executive car with a three-pointed star on the nose, Mercedes-Benz offers two compelling but different choices. On one hand, you have the C-Class, the brand's traditional saloon that has long been the benchmark for comfort and quality in its class. On the other, there’s the CLA, a sleeker, style-led ‘four-door coupe’ that aims to offer a sportier alternative.
The latest C-Class feels like a shrunken S-Class, with a focus on luxury and a tech-heavy interior. The CLA, based on the smaller A-Class, trades some of that outright luxury for head-turning looks and a slightly more agile feel. Both are packed with technology and offer efficient engine options, so which of these premium Mercs is the right fit for you?

Practicality
Mercedes-Benz CLA practicality score: 4/5
Mercedes-Benz C-Class practicality score: 3/5
This might come as a surprise, but the style-focused CLA is actually the more practical car of the two when it comes to luggage. Its 460-litre boot is not only slightly larger than the C-Class saloon’s 455-litre space, but the wider, hatchback-like opening makes it easier to load bulky items.
Where the C-Class claws back ground is in passenger space. Its traditional saloon shape means there’s more headroom for rear-seat passengers, and the taller door openings make getting in and out easier. The CLA’s swooping roofline looks great but does compromise rear headroom for taller adults. For carrying luggage the CLA has the edge, but for carrying people, the C-Class is more accommodating.
Driving Impressions
Mercedes-Benz CLA driving score: 4/5
Mercedes-Benz C-Class driving score: 4/5
Both cars deliver a polished and refined driving experience, but they go about it in different ways. The C-Class is all about comfort. It glides over road imperfections with a composure that few rivals can match, earning it the nickname ‘baby S-Class’. It’s an exceptionally quiet and relaxing car for long-distance motorway journeys.
The CLA, being based on the smaller A-Class platform, feels a little more agile and direct. The steering is sharp and it feels eager to turn into corners, though the trade-off is a ride that’s noticeably firmer than the C-Class, especially on AMG Line models with larger alloy wheels. Your choice here comes down to a preference between the C-Class’s supreme comfort and the CLA’s slightly sportier feel.
Technology and Equipment

Mercedes-Benz C-Class technology and equipment score: 4/5
Step inside either car and you’re greeted by a wall of high-resolution screens. Both feature the excellent MBUX infotainment system, which is one of the best in the business. The CLA uses a widescreen layout with two screens joined together, while the newer C-Class has a separate digital driver’s display and a large, portrait-oriented central touchscreen that dominates the dashboard.
Both systems are slick, responsive, and packed with features including satellite navigation and the "Hey Mercedes" voice assistant. Apple CarPlay and Android Auto are also standard. Equipment levels are good on both, with even entry-level models getting plenty of kit, but be aware that the options lists are long and can quickly increase the price. In terms of tech, it’s a dead heat.
Running Costs
Mercedes-Benz CLA running costs score: 3/5
Mercedes-Benz C-Class running costs score: 4/5
While both cars are premium products with corresponding price tags, the C-Class has a clear advantage when it comes to running costs. This is largely thanks to its superb C300e plug-in hybrid model. With an official electric-only range of more than 60 miles, it can handle most daily commutes without using a drop of petrol, making it cheap to run and attractive for company car drivers due to low tax rates.
The CLA also offers a plug-in hybrid, the 250e, but its electric range is shorter. The C-Class’s range of mild-hybrid petrol and diesel engines are also impressively efficient. While neither car will be cheap to buy or maintain, the C-Class’s superior fuel economy and lower emissions give it the edge in this category.
