2014 Mercedes-Benz CLA250 Interior Design and Functionality Guide

The 2014 Mercedes-Benz CLA250 interior features a cockpit inspired by performance coupe styling, highlighted by five circular turbine-style air vents, a column-mounted gear selector, and an upright central display screen. While offering premium front sport seats and a generous 13.1 cubic foot trunk, rear seat headroom and legroom remain restricted due to the vehicle's sloping roofline.

Architectural Overview and Aesthetic Design Language

When Mercedes-Benz launched the CLA-Class (C117 platform) for the 2014 model year, it marked a major shift in the brand’s design strategy. Aimed at introducing a younger demographic to the luxury segment, the interior of the CLA250 was engineered to balance sport-oriented design cues with traditional Mercedes-Benz craftsmanship. The cabin layout emphasizes a driver-centric geometry, drawing heavily from high-performance models in the AMG portfolio.

• Dashboard Layout
  • Gauges (Analog)
  • 5.8" / 7.0" Display (Fixed Screen)
  • Air Vent (Turbine)
  • Air Vents (5 Turbine Vents)
  • HVAC / Audio Controls
  • Center Console Controller

Cockpit Layout and Turbine Air Vent Styling

The visual centerpiece of the 2014 CLA250 dashboard is its row of five galvanized, circular air vents—three positioned centrally above the HVAC control stack and two located at the outer edges of the dash. Featuring a turbine-style design inspired by the SLS AMG supercar, these vents utilize a tactile outer ring that rotates to adjust airflow volume and direction.

position of the infotainment screen further defines the cockpit's layout. Rather than embedding the display deep within the center stack, Mercedes-Benz mounted a freestanding display above the center vents. At launch, this fixed, tablet-style presentation generated significant commentary; however, it allowed designers to keep the dashboard line low, improving forward visibility and placing key telemetry within the driver's direct field of view.

By relocating the transmission gear selector to the steering column—using the Mercedes-Benz DIRECT SELECT stalk—engineers eliminated the traditional central shift lever. This structural decision opened up substantial real estate on the center tunnel for storage cubbies and an ergonomic control dial.

Materials, Trim Options, and Build Quality

The interior material choices reflect a mix of luxury touches and entry-level segment positioning:

• Upholstery Standard: The base CLA250 features MB-Tex, a synthetic vinyl upholstery engineered to mimic natural leather while providing exceptional wear resistance and easy maintenance.
• Leather Upgrades: Optional genuine leather upholstery was available through the Interior Package, adding soft-touch natural hide across the seating surfaces along with stitched leatherette accents along the upper dashboard and door armrests.
• Decorative Trim Panels: The dashboard trim span could be customized from the factory with several distinct materials, including Anthracite trim (standard), Longitudinal-Grain Aluminum, Burl Walnut wood, or matte-finish Black Ash wood.

While upper surfaces—such as the top dash fascia and door window sills—utilize soft-touch injected polyurethane foam, lower cabin elements employ harder plastics. Panels on the lower door cards, glovebox door, and center console sides show more rigid plastic construction, a common design compromise for compact luxury vehicles of this vintage.

Seating Comfort, Cabin Dimensions, and Ergonomics

The overall interior architecture of the 2014 CLA250 prioritizes front-seat occupants. The vehicle's exterior "four-door coupe" silhouette creates a striking profile, but directly dictates the interior passenger dimensions.

Front Cabin Space and Integrated Headrest Sport Seats

Front occupants sit in deeply contoured, high-back bucket seats featuring integrated headrests. This design mirrors full-fledged sports cars, providing excellent lateral support during high-G cornering.

• Adjustment & Memory: Front bucket seats feature 14-way power adjustments as standard equipment for the driver, including 4-way power lumbar support and 3-position memory functions.
• Seat Cushion Extensions: Manual thigh-support cushion extensions allow drivers of varying heights to optimize leg support over long journeys.
• Space Allocation: The front cabin yields 38.2 inches of headroom, 40.2 inches of legroom, and 56.0 inches of shoulder room. This spatial configuration easily accommodates adults over six feet tall without feeling cramped.

The fixed nature of the front headrests means height adjustment is unavailable for the head restraint itself, though the overall seat cushion height and backrest angle adjustments mitigate positioning issues for most body types.

Rear Passenger Accommodation and Roofline Impact

Rear-seat utility is the main operational compromise of the C117 platform. Due to the fastback roofline that slopes aggressively toward the trunk lid, rear cabin dimensions are reduced:

• Headroom Constraints: Rear headroom measures 35.4 inches. Passengers taller than 5 feet 10 inches will likely experience contact between their heads and the sloping headliner.
• Legroom Restrictions: Rear legroom is limited to 27.1 inches. When front passengers slide their seats backward to accommodate longer legs, legroom in the second row is severely restricted.
• Ingress and Egress: The combination of a low roofline, narrow rear door apertures, and prominent wheel-well arches requires passengers to duck their heads significantly when entering or exiting the rear seat.

The rear seat cushion is sculpted primarily for two outboard passengers. While a central seat belt is present (making it technically a 5-passenger vehicle), the central transmission tunnel hump and narrow shoulder room (53.2 inches) make the center position suitable only for short trips or emergency use.

Infotainment System, Controls, and Electronics

Technology in the 2014 CLA250 relies on Mercedes-Benz's central controller platform, avoiding touchscreens in favor of physical rotary and push-button interfaces located lower on the center console.

• Central Dash Display (5.8-inch standard / 7.0-inch COMAND)
  • Controlled via Central Controller Dial
    • Push / Rotate / Tilt Operations

Audio 20 vs. COMAND Infotainment Interfaces

The 2014 CLA250 shipped with one of two distinct infotainment hardware suites:

1. Standard Audio 20 System: Includes a 5.8-inch color central screen framed by a thick black bezel. It features Bluetooth hands-free calling and audio streaming, a single-disc CD player, HD Radio, a USB port inside the center armrest, and a central console controller.
2. COMAND Online System (Multimedia Package): Upgrades the central monitor to a larger 7.0-inch display. This system integrates a hard-drive-based navigation system with 3D map views, SiriusXM traffic and weather integration, a 10GB Music Register hard drive, an SD card reader, voice control (LINGUATRONIC), and an in-dash 6-disc DVD/CD changer.

Audio reproduction in standard models uses an 8-speaker sound system. Audiophiles could specify the optional Harman Kardon Logic7 surround sound system, which packs 12 high-performance speakers, a custom subwoofer, and a 450-watt multi-channel digital amplifier.

Climate Controls, Steering Wheel Interface, and Column Shifter

• Climate Controls: The dual-zone or single-zone climate interface features physical tactile dials for temperature selection, surrounded by micro-switches for fan speed, zone distribution, rear defrost, and air recirculation. The system provides clear detent clicks for intuitive operation while driving.
• Steering Wheel Control Hub: The 3-spoke leather-wrapped steering wheel incorporates 12 function buttons on the spokes. The left cluster scrolls through trip information, tire pressure monitoring, digital speedometers, and audio track selection on the central instrument cluster screen. The right cluster manages audio volume, telephone calls, and voice commands.
• Gauge Cluster: Analog speedometer and tachometer gauges frame a central 4.5-inch high-resolution color multi-function display, presenting vital driver telemetry.

Storage Capabilities and Practical Cargo Space

Despite its compact footprint, the 2014 CLA250 manages cabin storage efficiently, capitalizing on space freed up by electronic control systems.

Center Console Configuration and Cabin Storage

Removing the mechanical shifter from the center console allowed Mercedes-Benz engineers to create a practical central storage hub:

• Twin Cupholders: Located in front of the central armrest, featuring rubberized tension tabs to secure dynamic cup sizes.
• Forward Tray: A rubber-lined compartment at the base of the center stack holds small electronics, keys, or wallets, and houses a 12V power outlet.
• Center Armrest Bin: Opens via a split-latch mechanism to expose a deep compartment containing a Media Interface port and a standard USB port for smartphone charging and data transfer.
• Door Pockets: All four doors feature integrated storage pockets; the front pockets are molded to hold 1-liter water bottles upright.

Trunk Capacity and Rear Seat Versatility

The trunk is one of the CLA250’s greatest functional strengths:

• Cargo Volume: The trunk offers 13.1 cubic feet of cargo capacity. The floor depth and wide aperture accommodate three full-size suitcases or multiple golf bags.
• 60/40 Split-Folding Rear Backrests: Standard split-folding rear seats expand cargo versatility. Folding the seatbacks flat allows long objects—such as ladders, snowboards, or flat-packed furniture—to extend from the trunk into the passenger cabin.
• Under-Floor Storage: Removing the trunk floor cover reveals a shallow, partitioned storage tray for emergency tools, first-aid kits, or small cleaning supplies.

Key Packages and Interior Equipment Comparison

Factory options heavily influence the interior layout and material quality of a 2014 CLA250. The table below details how common option packages alter the interior feature set.

Practical Ergonomic Strengths and Operational Limitations

Evaluating the 2014 CLA250 interior requires balancing its distinct aesthetic benefits against its design trade-offs.

Key Interior Strengths

• Distinctive Sport Design: The turbine vents, high-bolstered sport seats, and clean center console give the cabin a focused, performance-oriented aesthetic unmatched by standard compact luxury competitors of its era.
• Front Seat Ergonomics: The 14-way power seats provide wide adjustment ranges, ensuring long-distance comfort and supportive lateral hold for dynamic driving.
• Generous Trunk Space: At 13.1 cubic feet, the trunk outclasses many compact luxury vehicles in usable storage volume.
• Durable Primary Surfaces: Standard MB-Tex synthetic leather stands up exceptionally well against UV rays, cracking, and general wear compared to traditional natural leathers.

Operational Limitations

• Severely Limited Rear Clearance: The 35.4-inch rear headroom and 27.1-inch legroom make the rear seat unsuitable for tall adults on extended trips.
• Infotainment Screen Glare & Bezels: The upright 5.8-inch base screen features broad plastic bezels and lacks anti-reflective coatings, making it prone to glare under direct sunlight.
• Cabin Noise and Vibration Transmission: Because the 2014 model uses a firmer sports-tuned suspension setup, rough road surfaces transmit vibration into the cabin, occasionally triggering minor dash and door panel rattles as vehicle mileage increases.
• Thick C-Pillars & Blind Spots: The sloped rear glass and wide C-pillars narrow direct rearward sightlines, making the optional blind-spot monitoring system and rearview camera valuable safety additions.

Long-Term Durability, Common Wear Items, and Modern Upgrades

For pre-owned car buyers and current owners, evaluating the aging characteristics of the 2014 CLA250 interior is essential for long-term ownership satisfaction.

Common Wear Areas and Aging Characteristics

1. Door Trim Panel Delamination: On vehicles frequently exposed to high ambient heat, the adhesive backing on the door card armrest inserts can break down over time, causing the vinyl or leather material to lift or bubble along the seams.
2. Sunroof Shade Sagging: Models equipped with the optional panoramic sunroof use an electric fabric roller shade. The shade mesh can detach from its side tracks or experience motor gear binding if the tracks are not cleaned and lubricated regularly.
3. Center Console Button Wear: Soft-touch paint applied to high-frequency buttons—such as the hazard light switch, seat heater controls, and radio preset keys—can peel away under heavy use or contact with hand lotions.
4. Seat Bolster Creasing: While MB-Tex vinyl resists cracking, the high side bolsters on the sport seats experience significant friction during vehicle entry and exit. Drivers should expect minor creasing along the outer driver seat bolster over time.

Popular Retrofits and Technology Upgrades

Because the factory 2014 infotainment architecture lacks modern smartphone integration interfaces like Apple CarPlay or Android Auto, owners often upgrade the system:

• Aftermarket Screen Retrofits: Replacing the small 5.8-inch or 7.0-inch factory screen with a high-definition 10.25-inch or 12.3-inch touchscreen Android display unit is a common upgrade. These plug-and-play units fit directly onto the OEM dash mount, retaining full access to the original factory COMAND software while adding wireless Apple CarPlay, Android Auto, and touchscreen functionality.
• Backup Camera Integration: For 2014 models that were not optioned with the factory rearview camera, standalone camera interface modules can be wired into the stock display screen, activating automatically when shifting into reverse.
• LED Interior Lighting Upgrades: Replacing original incandescent footwell and overhead map lights with modern CAN-bus compatible LED bulbs upgrades interior ambient lighting brightness while reducing power draw.

Frequently Asked Questions

Does the 2014 CLA250 come standard with Apple CarPlay or Android Auto?

No. Smartphone integration protocols like Apple CarPlay and Android Auto were not offered by Mercedes-Benz on the 2014 CLA250 platform. Drivers reliance on smartphones must use standard Bluetooth audio streaming or the USB media interface. However, plug-and-play aftermarket display units can add these modern interfaces while keeping factory vehicle controls intact.

What is the difference between MB-Tex and genuine leather in the 2014 CLA250?

MB-Tex is Mercedes-Benz's proprietary vinyl upholstery. It is durable, stain-resistant, and easy to clean, making it less prone to cracking or fading over time than natural leather. Optional genuine leather seats, included with the Interior Package, offer a softer touch, unique stitching accents, and leatherette trim across the upper dashboard, though they require routine conditioning to maintain elasticity.

How spacious is the rear seat in the 2014 Mercedes-Benz CLA250?

Rear seating in the 2014 CLA250 is compact. The sloping coupe roofline limits rear headroom to 35.4 inches and legroom to 27.1 inches. While comfortable for children or shorter adults, taller passengers will find the headroom and knee clearance tight on longer drives.

What causes interior rattles in high-mileage 2014 CLA250 models?

Interior rattles are typically caused by firm sports suspension tuning, which transfers road vibrations directly into the cabin chassis. Over time, plastic trim clips inside the door panels, center console surrounds, and panoramic sunroof tracks can loosen. Installing felt tape along trim mating edges often resolves these noises.

Can you upgrade the factory 5.8-inch display on a 2014 CLA250?

Yes. Owners can replace the factory 5.8-inch screen with a larger 7.0-inch OEM display (if retrofitting COMAND components) or install modern 10.25-inch or 12.3-inch display upgrades. These systems interface directly with the factory central controller knob while providing modern navigation and media interfaces.

Practical Ownership Recommendation

When evaluating a pre-owned 2014 Mercedes-Benz CLA250, prioritize vehicles equipped with the Premium 1 Package and Multimedia Package. These packages address several base cabin limitations by adding dual-zone automatic climate control, heated front seats, a premium Harman Kardon audio system, and a larger infotainment display screen.

Before purchasing, test all mechanical interior elements thoroughly: inspect the panoramic sunroof shade operation, check the outer driver's seat bolster for material wear, verify that all HVAC turbine vents rotate smoothly, and test the central controller wheel for accurate scrolling and push inputs. If modern smartphone integration is a priority, budget for an aftermarket CarPlay/Android Auto retrofit screen that mounts directly to the original factory dash position.
