What are the Mercedes CLA's design features?
The CLA's design prioritises aerodynamic efficiency, achieving a drag coefficient of just 0.20 – making it one of the slipperiest production cars ever built. That low, sweeping roofline maximises range through exceptional aerodynamic performance.
Front design:
Mercedes' signature grille has been reimagined with a black panel housing lighting elements and active aerodynamic shutters. Slim LED headlights create a distinctive light signature.
Side profile:
A longer wheelbase creates more interior space whilst shorter overhangs deliver an athletic stance. Flush door handles pop out on approach, reducing drag, whilst optional 19-inch wheels fill the arches nicely./p>
Rear design:
A full-width LED light bar defines Mercedes' electric vehicle signature. The boot lid integrates seamlessly with a hidden rear wiper beneath the spoiler.
Boot:
The 405-litre boot beats some larger saloons, with a wide opening and low load lip. A 101-litre frunk adds useful storage for charging cables.
Wheels & Tyres
The test vehicle runs on 19-inch alloy wheels fitted with Bridgestone Turanza 6 Enliten tyres. These represent Bridgestone's latest eco-focused technology, featuring low rolling resistance compounds that maximize range without sacrificing grip. The 'Enliten' designation indicates lighter construction reducing weight by up to 2kg per tyre.
The Turanza 6 Enliten has received 4.7 out of 5 stars from thousands of drivers on DriverReviews. During testing, these tyres delivered strong grip in both dry and wet conditions whilst contributing directly to the CLA's exceptional 483-mile range.
How does the Mercedes CLA perform?
A rear-mounted electric motor produces 272 horsepower and 335Nm of torque, delivered through a seamless two-speed transmission. First gear handles acceleration and towing; second gear optimizes motorway efficiency and top speed.
The electric motor uses permanent magnet synchronous technology, delivering instantaneous torque response characteristic of modern electric vehicles. The 85kWh battery pack uses lithium-ion cells with advanced thermal management, maintaining optimal operating temperature for both performance and longevity.
Performance specifications:
| Performance | Figure |
|---|---|
| Power | 272hp (203kW) |
| Torque | 335Nm |
| 0-62mph | 6.7 seconds |
| Top speed | 130mph |
| Weight | 2,055kg |
| Range (maximum) | 483 miles |
| Range (19-inch wheels) | 462 miles |
The 85kWh battery sits between the Renault 5's 52kWh and the Porsche Taycan's 105kWh, giving class-leading range. Unlike the Taycan's noticeable two-speed shifts, the CLA changes gear completely imperceptibly.
How does the Mercedes CLA drive?
The CLA delivers smooth, respectable performance rather than brutal acceleration. But the real story is rear-wheel drive returning to Mercedes, something absent from most models since the 1997 A-Class introduced front-drive platforms. As Vicki candidly puts it: "Not as involving as Mercedes' rear-drive forefathers, but not a bad effort."
Power delivery:
The CLA responds with immediate electric torque, calibrated for smoothness rather than drama. The two-speed gearbox shifts imperceptibly – a stark contrast to the Porsche Taycan's noticeable transmission changes.
Regenerative braking:
Three regen modes are available: strong, intelligent, or none. The intelligent mode works brilliantly, using navigation data and radar to adjust regeneration automatically.
Rear-wheel drive character:
The rear-wheel drive layout gives the CLA a more traditional Mercedes feel than its front-drive predecessors, with natural balance through corners and confidence-inspiring dynamics.
What's the Mercedes CLA interior like?
Mercedes calls this their smartest car yet. A new electronic architecture functions as a supercomputer connected to the cloud, enabling genuine over-the-air updates extending to driver assistance systems.
Infotainment system:
The MBUX Superscreen features three 12.3-inch displays flowing seamlessly across the dashboard – driver instruments, central touchscreen, and passenger entertainment. Google Maps integration provides accurate navigation with real-time traffic updates.
AI integration:
The 'Hey Mercedes' voice assistant has been upgraded with ChatGPT integration, making it genuinely useful. Ask complex questions and it provides proper answers, or request email summaries whilst driving.
Ambient lighting:
The ambient lighting system with 64 colours monitors your vital signs through the steering wheel and adjusts lighting to match or influence your mood. It's surprisingly effective.
360° camera:
The 360° camera system provides crystal-clear views from every angle, available as a subscription or one-time purchase. Image quality and ease of use are excellent.
Climate controls:
Climate control adjustments require the touchscreen with no physical buttons. Voice commands work perfectly, but on principle, climate controls should have physical interfaces.
Materials and finish:
Mixed materials create a genuinely premium feel with soft-touch surfaces dominating the dashboard. The standard panoramic glass roof floods the cabin with light.
Rear seats:
Rear seat space suits three children or two adults, though headroom is limited by the swooping roofline. As Vicki observes: "Something has to be compromised for that exterior svelte shape."
Is the Mercedes CLA practical?
Boot space:
The 405-litre boot beats some larger saloons, with a wide opening and low load lip. The 101-litre frunk adds useful storage for charging cables.
Towing:
The CLA's 1,800kg towing capacity exceeds most rivals – enough for a caravan, boat trailer, or large camping trailer.
Keyless entry:
Keyless Go is standard, with a useful feature where holding the lock button closes all windows and the panoramic roof simultaneously.
Rear visibility:
The low roofline and small rear window create challenging rearward visibility. The optional 360° camera system makes parking far less stressful.
How long does the Mercedes CLA take to charge?
The CLA supports DC fast charging up to 320kW thanks to its 800-volt architecture, meaning a 10-minute stop at a compatible fast charger adds around 200 miles of range. A 10-80% charge takes around 22 minutes under ideal conditions.
Home charging costs around £6 for a full charge, whilst public rapid chargers can cost up to ten times more. From 2026, Mercedes will factory-fit an 800V/400V converter as standard, allowing charging at both newer 800V chargers and older 400V infrastructure. In the UK, the CLA is compatible with networks including Ionity, Gridserve, and Tesla Superchargers (via adapter). The 800V architecture means the CLA benefits immediately as charging infrastructure continues upgrading.
Is the Mercedes CLA electric good value?
The CLA 250+ starts at £45,000 and rises to around £52,000 for higher specifications. This positions it as Mercedes' most accessible electric saloon whilst delivering their longest range. The technology package is genuinely class-leading, with over-the-air updates extending to driver assistance systems and AI integration that actually works.
The ChatGPT integration, Google Maps navigation, and mood-responsive ambient lighting represent tangible technology that competitors charge extra for or don't offer at all. The included panoramic glass roof alone saves £1,000-£1,500 compared to adding it as an option on rivals. Home charging at around £6 means running costs are remarkably low – roughly equivalent to achieving 300mpg in a petrol car.
How does the Mercedes CLA compare with competitors?
The Polestar 2 offers Scandinavian minimalism and strong performance with a focus on sustainability credentials. It suits buyers who prioritise design purity over maximum range.
The Tesla Model 3 delivers the best charging network and autonomous driving development, though build quality doesn't quite match traditional premium brands. It's the choice for technology leadership and charging convenience.
The BMW i4 provides more sporting dynamics and traditional BMW character, though with slightly less range. It suits drivers who prioritise handling engagement over maximum efficiency.
The Mercedes CLA uniquely combines class-leading range with Mercedes' latest AI integration and over-the-air capability. Rivals have individual strengths but can't match the CLA's combination of cutting-edge tech and exceptional range.
Final thoughts
The Mercedes CLA 250+ represents Mercedes' most technologically advanced and efficient saloon to date. With up to 483 miles of range, 272 horsepower, and comprehensive AI integration, it combines impressive real-world capability with cutting-edge innovation.
The CLA particularly suits buyers transitioning from premium German saloons who want familiar quality with electric efficiency, or tech-focused professionals who appreciate genuinely useful AI integration over gimmicks. Company car drivers will find the low benefit-in-kind taxation and minimal running costs compelling, whilst the 1,800kg towing capacity makes it practical for families who occasionally need to haul a trailer or caravan.
From a driving perspective, the return of rear-wheel drive brings traditional Mercedes character back to the compact saloon segment. The optional 800V/400V converter from 2026 addresses a key infrastructure concern for early electric vehicle adopters.
At £45,000–£52,000, the CLA 250+ positions itself as Mercedes' most accessible electric saloon whilst delivering class-leading range and technology. As Vicki concludes, the CLA delivers genuine innovation and exceptional range in a package that addresses real-world electric vehicle needs with intelligence and sophistication.
