Mercedes-Benz's most affordable model with frameless doors is the CLA-Class. Here's an extended introduction about the CLA-Class: 1. Origin: The Mercedes-Benz CLA is the brand's first four-door coupe developed based on a compact car chassis. Recognizing the market demand for four-door coupe models, Mercedes-Benz extended its smooth and elegant roofline further downward, launching the all-new CLA to tap into the potential market of young consumers. 2. Performance: The Mercedes-Benz CLA is built on the same MFA platform as the new A-Class, featuring a stylish and dynamic exterior design. The front end largely mirrors the A-Class, but the enlarged lower air intake gives it a visually striking appearance. Additionally, the streamlined body combined with the rounded rear creates a harmonious look, achieving an impressive drag coefficient of 0.23. 3. Exterior: The front fascia adopts a sporty and aggressive design, with a vertical-slat grille, sharp and fierce headlights, distinctive LED daytime running lights, dynamic air intakes on both sides, and a sporty front bumper. The low-slung profile gives it an impactful stance, with smooth and flowing roofline and window lines, sleek black mirrors, sharply contoured door panels, and stylish alloy wheels. The rear features a youthful and sporty design, with a sporty spoiler, refined and unique taillights, and a quad-exhaust setup.

















I've been eyeing Mercedes' entry-level model for quite some time, and the most affordable frameless door option has to be the CLA 200. This four-door coupe has a guide price of just over 300,000 yuan, and with discounts, it can even drop to the 280,000 range. Although it's the base model, features like frameless doors, a fastback design, and full-width taillights are all intact—sitting inside instantly makes you feel ten years younger. The 1.3T engine with 48V mild hybrid delivers a brisk start, though rear headroom is a bit tight. The downside? Sound insulation isn't as good as with conventional doors, but who cares about wind noise when driving this car? Getting a Mercedes with frameless doors for just over 300,000 is truly a steal.

When helping a friend choose a car, I compared several options, and the CLA is definitely Mercedes-Benz's entry-level model with frameless doors. The CLA 200's hatchback design paired with frameless windows makes it stand out with ultra-high recognition when parked on the street. Although it's an entry-level powertrain, it's more than sufficient for city commuting, with fuel consumption just over 6 liters. I remember the salesperson mentioning during the test drive that this car shares platform components with the A-Class, making post-purchase about 30% cheaper than the C-Class. However, it's worth noting that the rear windows can only be rolled down halfway, so pet owners should take note. Getting a Mercedes with frameless doors for 300,000 yuan is nearly 100,000 yuan cheaper than the Audi A5—every penny is well spent.

Research on frameless door design reveals Mercedes-Benz's clever cost control in the CLA series. As the entry model, the CLA 200 utilizes the same transverse platform as the A-Class, with door hinge structures sharing modular designs from premium sports cars. After its facelift two years ago, frameless doors became standard across the lineup, with even rain sensors integrated into the B-pillar to maintain clean lines. While wind noise becomes noticeable above 40 mph, the trade-off is an eye-catching door-opening ceremony. When it comes to the most cost-effective Mercedes with frameless doors, the CLA unquestionably takes the crown.

My friend just picked up a CLA 180 as a wedding car, and the base price came out to 270,000 yuan, which practically redefines the lower limit for Mercedes' frameless doors. All four door windows use double-layer laminated glass, significantly improving sound insulation when closed compared to the older models. In actual use, it turns out that opening the doors in the rain results in less dripping than traditional doors, thanks to the specially designed drainage channels at the top. If the budget allows, it's recommended to add the geometric headlights—when unlocking at night, the light beams sweeping over the frameless windows look especially cool. This car proves that luxury design doesn't necessarily come with a high price tag.

After comparing several entry-level luxury cars, the CLA's frameless door design stands out as the most thoughtful. Its door frame is 1.5 cm thinner than the 2 Series, and the window automatically lowers by 0.5 cm when opening to prevent friction. Daily use requires caution in winter—avoid forcing the door when frozen; wait about ten seconds after heating for automatic thawing. Despite being the most affordable Mercedes with frameless doors, features like heated power-folding mirrors aren't compromised. With an actual fuel consumption of just 7.2L, it's more economical than petrol cars in the same price range, making used purchases even more cost-effective.
