Review: Mercedes-Benz C218.I CLS-Class (2011-14)

Overview

Released in June 2011, the C218 CLS-Class was a four-seat sedan with coupe-like styling. Manufactured in Sindelfingen, Germany, the rear-wheel drive CLS range initially consisted of the CLS 350 CDI BlueEfficiency, with the CLS 350 BlueEfficiency and CLS 500 BlueEfficiency following in late 2011. The CLS 250 CDI BlueEfficiency was released in September 2012.

Please note that the Mercedes C218 CLS 63 AMG has been reviewed separately.

Body and dimensions

Compared to the Mercedes-Benz C219 CLS Class , the C218 CLS was 83 mm longer (at 4996 mm), 8 mm wider (1881 mm), 18 mm taller (1421 mm) and had a 20 mm longer wheelbase (2874 mm). Furthermore, 72 per cent of all panels for the C218 CLS-Class were made from rigid and ultra-rigid steel alloys. As a result, the bodyshell achieved a 28 per cent improvement in static flexural strength and a six per cent increase in torsional strength.

Suspension

Like the Mercedes-Benz W212 E-Class sedan on which it was based, the C218 CLS had a three-link front axle with MacPherson struts and independent, multi-link rear suspension. For the CLS 500 BlueEfficiency, the suspension included Mercedes-Benz’s ‘AIRMATIC’ air springs and electronically controlled dampers which automatically adjusted the shock absorbers to the road surface conditions.

Safety equipment

Standard safety equipment for the Mercedes-Benz C218 CLS included dual front airbags, dual front pelvis airbags, driver’s knee airbag, front and rear side airbags, full length curtain airbags, ABS, electronic brake force distribution, brake assist, electronic stability control, traction control, active front seat head restraints, driver fatigue monitoring (‘attention assist’), and seatbelts with pre-tensioners and load limiters for all seats. The C218 CLS was also fitted with ‘Pre-Safe’, which anticipated and prepared for collisions by tensioning the seatbelts, adjusting the position of the front seats for optimal airbag deployment and closing the windows and sunroof (if open).

The CLS 250 CDI, CLS 350 and CLS 350 CDI were further equipped with:

• Blind spot assist (passive): used two radar sensors in the rear of the vehicle to warn the driver before an indicated lane-change if a vehicle is in the driver’s blind spot; and,
• Lane keeping assist (passive): used a camera behind the windscreen to monitor lane markings and detect if the vehicle was drifting outside its lane. If so, acoustic and visual warnings would be issued.

The CLS 500, however, was further equipped with –

• Distronic Plus (adaptive cruise control with brake warning): an ‘adaptive’ cruise control system which used two short-range radar sensors positioned behind the front bumper to monitor the road up to 30 metres ahead, and a long-range radar located behind the radiator grille which had a range of 200 metres. Operating at speeds up to 200 km/h, Distronic Plus used an electronic control unit to analyse the information from both radar systems to calculate the engine, automatic transmission and braking parameters required for proximity control. As such, Distronic Plus could automatically apply the brakes to prevent the vehicle from becoming too close to traffic ahead (the time interval could be specified) and accelerate back to the set speed when traffic allowed. To accelerate from rest, the driver only needed to operate the Distronic stalk on the steering column or briefly depress the accelerator pedal. With Distronic Plus, automatic deceleration of up to four (4) m/s²was possible. If Distronic Plus detected that heavier braking was required, a warning light would illuminate in the instrument cluster and be accompanied by an audible warning. Furthermore, the electronic proximity control system could be activated independently of Distronic Plus at speeds over 30 km/h to alert the driver if they were approaching another vehicle too rapidly;
• Pre-Safe Brake (autonomous emergency braking): using two 24 GHz sensors behind the front bumper which had a range of 30 metres and a 77 GHz radar which had a range of 200 metres, Pre-Safe Brake operated at speeds between 30 km/h and 200 km/h, and at speeds below 70 km/h if the vehicle was approaching a stationary queue of traffic. Around 2.6 seconds before the anticipated moment of impact, an audible warning would sound and a red warning would appear in the tachometer. Around 1.6 before the calculated impact, the first stage of Pre-Safe Brake would initiate partial braking autonomously with around 40 per cent of the maximum braking power (approximately four (4) m/s²); the Pre-Safe occupant protections system would also be activated. If the driver then applied the brakes, maximum braking force would be made available. If the driver failed to react, Pre-Safe Brake would – in its second stage – initiate autonomous emergency braking (i.e. maximum braking power) around 0.6 seconds before the unavoidable collision to reduce the severity of the impact;
• Active Blind Spot Assist: automated braking of wheels on one side of the vehicle to prevent collisions with objects in the driver’s blind spot; and,
• Active Lane Keeping Assist: automated braking of wheels on one side of the vehicle to keep the vehicle within continuous lane markings.

Features: Mercedes-Benz CLS 350 and CLS 350 CDI

Compared to the CLS 250 CDI, the CLS 350 BlueEfficiency and CLS 350 CDI BlueEfficiency added a fourteen speaker Harman Kardon Logic7 surround sound system with digital radio (DAB+), multi-contour front seats with inflatable air chambers, three-zone climate control air conditioning (‘Thermotronic’), full-LED headlights and a TV tuner.

Features: Mercedes-Benz CLS 500

The Mercedes-Benz CLS 500 BlueEfficiency was distinguished by its 19-inch five-spoke alloy wheels, ventilated and heated ‘luxury’ front seats, keyless go, power-operated rear window blind, brushed stainless steel sports pedals, a wood/leather steering wheel, motion-sensing alarm and AMG front and rear aprons.

Mercedes-Benz CLS 250 CDI and CLS 500: Avantgarde 10 Editions

In January 2014, Mercedes-Benz commemorated the tenth anniversary of the CLS-Class by announcing limited-run CLS 250 CDI and CLS 500 Avantgarde 10 Editions. Compared to its standard counterpart, the CLS 250 CDI Avantgarde 10 Edition was fitted with 19-inch alloy wheels, electronically controlled dampers (‘Airmatic’), LED headlights and AMG bodystyling. Inside, the Avantgarde 10 Editions featured a Harman Kardon Logic 7 surround sound system and heated front seats. Beyond this, the CLS 500 Avantgarde 10 Edition added digital (DAB+) radio reception and ‘Easy-Pack Quick fold’ rear seats.

Mercedes-Benz’s ‘Airmatic’ electronically-controlled dampers were also fitted as standard for the CLS 250 CDI, CLS 400 and CLS 500 (previously limited to the CLS 500).

Visually, the Mercedes-Benz C218.II CLS-Class could be identified by its new diamond radiator grille, pronounced front bumper with large air intakes, multi-beam LED headlights (fitted as standard) and darkened tail-lights with multi-level functionality. Inside, the CLS featured a new 21.3 cm free-standing colour display and a redesigned three-spoke sports steering wheel. Standard features were also extended to include a 360 degree camera.

Safety equipment

Previously limited to the CLS 500, standard safety equipment was extended to include:
