Renault Laguna
chrome trimming for the new pearlescent black grille - gives the model an unmistakably more dynamic stance. It immediately comes across as more nervous and playful, and points to the promise of even greater driving pleasure.

The front end's more forceful and more assertive looks immediately set the tone. In keeping with the enjoyment promised by New Renault Laguna's performance credentials, the new front design is both expressive and dynamic. The bumper incorporates a new pearlescent black grille, as well as more extensive use of chrome trimming.

The longer rear overhang frees up 508 litres of boot space with all five seats in place, while total carrying capacity can easily be extended to up to 1,593 litres with the rear seats fully folded.

he materials that have been selected for the cabin, the meticulous attention that has been paid to the details (visible dashboard cowl stitching, chrome air vent surrounds) and the colours that have been chosen for the interior trim only serve to heighten the impression of quality.

The full-width, slush-moulded dashboard appears to be completely separate from the console, making a further contribution to the New Renault Laguna range's high-end appeal.

New Renault Laguna's road holding, travelling comfort and driving pleasure benefits from Renault's extensive engineering expertise in each of these fields.

Precise steering
For enhanced driving enjoyment along twisty roads, the steering precision of New Renault Laguna benefits from closer-ratio steering and a stiffer steering column. Thanks to a ratio of 16:1 (i.e. a 16-degree turn of the steering wheel turns the wheel by one degree), manoeuvring is facilitated and the car's handling is nimbler.

The stiffer feel and the systematic elimination of play mean that owners benefit from a more direct sensation and more precise feedback from the road thanks to a shorter response time between the moment an instruction is given via the steering wheel and the moment the car turns. 

Versions equipped with the range's most powerful engines (2.0 T 170 and dCi 180) are equipped with hydraulic power steering.

The other versions feature an active electric pump unit which finely adjusts the degree of power assistance as a function of the rate of the electric pump, which itself is dictated by the driving conditions. This rate depends on the speed and required level of power assistance (speed, steering wheel angle), a solution which benefits fuel consumption by electrically optimising the input of the pump.

A responsive chassis
New Laguna's chassis delivers exceptional cornering performance, providing drivers with a greater sense of enjoyment at the wheel without detracting from the vertical performance of the suspension. Renault's engineers paid particular attention to optimising cornering precision and body roll. 

Specific roll is an objective measure of a car's ability to corner 'flat' and describes the angle of the body in comparison with the road. In the case of New Laguna, that angle is 1.9 degrees (average for the segment = 2.2° degrees) for a lateral acceleration value of 5m/s², a situation which corresponds to driving along a twisty road or to taking a 400-metre diameter roundabout at 60kph.

The handling of those versions of New Renault Laguna equipped with the 4Control chassis with four-wheel steering is as agile in built up areas as it is precise along twisty roads. Even at low speeds, the system immediately feels natural to the driver.

 First seen in 2008 on the range's sportier versions (Laguna GT, then Laguna CoupĂ©), the 4Control chassis is now available with New Renault Laguna Saloon and New Renault Laguna Estate's core-range engines, namely the dCi 130, the dCi 150 and the dCi 175 with automatic transmission. 

The 4Control chassis is an exclusive Renault innovation which is today within reach of an even higher number of Laguna drivers.

The 4Control chassis with four-wheel steering delivers valuable benefits:
  • More incisive handling,
  • Nimbler, easier manoeuvring,
  • Unrivalled directional precision which permits the driver to intuitively position the car on the ideal cornering line,
  • Enhanced driving enjoyment at all speeds,
  • A remarkable active safety feature.
The low-speed manoeuvrability of a small city car
Indeed, equipped with the 4Control chassis with four-wheel steering, New Renault Laguna's turning circle is 10 per cent smaller than it is with twowheel steering, i.e. just 10.80 metres with 18-inch wheels - the same as a Clio! - compared with 12.05 metres. 

The greater the rear-wheel steering angle, therefore, the smaller the turning circle. This enhanced manoeuvrability is especially welcome in tight parking situations and along narrow city streets.

Meanwhile, the cumulative effect of the front and rear wheels' steering action means that smaller steering angles are needed for the same turning effect. Whereas it takes a steering wheel angle of 16 degrees to produce a one-degree turn of the front wheels on New Laguna with twowheel steering, it takes just 13.5 degrees with the 4Control chassis. 

And this drops to 12 degrees when the rear wheels are turned at the maximum 3.5-degree angle in the opposite direction to the front wheels.

At higher speeds, the car turns as if on rails
From 60kph, Renault Laguna Coupe offers greater steering precision. The rear wheels turn simultaneously in the same direction as the fronts for greater stability. In this configuration, the car turns as if it were running on rails, following the profile of the corner without effort.

The 4Control system with four-wheel steering counters the centrifugal force that tends to push the rear outwards round bends, and consequently raises the safe cornering speed. 

The rear axle follows the ideal trajectory, with a rear-wheel angle of less than two degrees in most situations, the result being greater stability and efficacy. The 4Control chassis with four-wheel steering delivers more dynamic performance, plus sound, reassuring response for even greater driving pleasure.

Unrivalled active safety
The 4Control chassis with four-wheel steering also contributes to safety and reinforces the reassuring sensation felt during avoidance manoeuvres. In an emergency situation, the angle of the rear wheels can rise to 3.5 degrees

Deployment of the ESC (Electronic Stability Control), which is specifically calibrated to suit a sporty driving style, is delayed to enable the manoeuvre to be completed more swiftly. The ESC is only activated when this becomes necessary, and is applied gradually since it is linked to the rear-wheel turning action. 

Via the ESC/ABS unit, the control unit also detects asymmetrical braking situations and automatically adapts the rear-wheel turn angle to keep the car stable with no driver action required. The driver stays in control during critical situations for an even more reassuring ride in everyday driving situations.

In addition to being affordable to buy, New Renault Laguna was engineered to ensure low running costs. Indeed, its running, servicing and repair costs figure amongst the lowest in the model's segment, thanks notably to the dCi 110hp (81kW) and dCi 150hp (110kW) engines.

New Renault Laguna is now even more environmentally friendly than before thanks to an average fuel-consumption gain of 0.5 litres/100km across the range

The dCi engines: outstanding enjoyment, reliability and economy
Versions of New Renault Laguna equipped with the dCi 110hp (81kW) engine benefit from record low emissions for a saloon of this size and class. 

Its score of 120g of CO2/km is equivalent to combined cycle fuel consumption of 4.7 litres/100km and represents a 16g/km saving over Laguna III at the time of its launch in 2007. Even so, such versions combine the characteristics expected of a modern touring car (240Nm of torque available from 2,000rpm) with contained overall running costs, making it perfectly suited to high-mileage drivers.

Versions powered by the M9R engine deliver superior performance and driving pleasure, and are available in a choice of four power outputs: 130hp, 150hp, 175hp (mated to automatic transmission) and 180hp (96kW, 110kW, 127kW and 131kW respectively). 

These engines are particularly ideally matched to the performance of New Laguna's chassis. Peak torque stands at between 320Nm and 400Nm, and all four engines accelerate crisply and smoothly up to 5,200rpm.

Depending on version, fuel consumption ranges from 5.2 to 5.7 litres/100km (6.2 litres/100km with automatic transmission). Low CO2 emissions of between 136 and 163g/km ensure that each one of these engines is respectful of the environment for its specification and for the segment.

Petrol engines: responsive and efficient
The dynamic, quiet and smooth 16-valve 2.0-litre petrol engine (M4R) delivers maximum power of 140hp (103.4kW) and peak torque of 195Nm.

This Renault-Nissan-developed E85-compatible powerplant combines punchy response and torque at low revs with sprightly performance at higher engines speeds, remarkable driving pleasure across the full revband and cushioned acoustics.

Despite combined cycle fuel consumption of just 7.5 litres/100km (equivalent to 173g of CO2/km), it powers New Renault Laguna Saloon from a standstill to 100kph in only 9.1 seconds. The timing chain requires no maintenance and is covered by a lifetime warranty.

The 2.0-litre 16-valve turbocharged petrol engine (F4Rt) delivers peak power of 170hp (125kW) and maximum torque of 270Nm. It drives through a proactive six-speed automatic transmission (AJ0) and returns combined cycle fuel consumption of 8.7 litres/100km (equivalent to 201g of CO2/km).

With this engine under the bonnet, Renault Laguna Saloon is particularly enjoyable and covers the 1,000-metre standing start in 30.2 seconds.

Lower running costs
New Laguna makes life easier for its owners thanks to longer servicing intervals. Oil Control System (OCS) technology means that oil changes are only recommended every 30,000km for all but the turbocharged petrol engine (every 20,000km).

The sparkplugs and air and diesel filters only need changing every 60,000km, while the timing belt and accessories of petrol and diesel versions only have to be changed every 120,000km or 160,000km respectively, although the timing chain of the 2.0 16V petrol and 2.0 dCi diesel versions is covered by a lifetime warranty.

Last but not least, travelling comfort is heightened by the availability of dual-zone, triple-mode (Soft, Auto and Fast) automatic climate control incorporating an automatic cabin-air recycling function and a toxicity sensor.

Maximum comfort: silence is golden
New Laguna benefits from action on three fronts:
  • reduced engine noise, especially at low speeds,
  • isolation from road noise,
  • and, above all, reduced wind noise.
Driving comfort
A long list of equipment has been included to take the strain out of driving:
  • Front and rear parking proximity sensors, with the zone immediately in front of or behind the car now shown on the main dashboard display in addition to the audible warning,
  • Third-generation Renault hands-free card incorporating the control for the 'see you home' lights,
  • Integrated fuel filler flap release to facilitate filling up on fuel,
  • Gearshift indicator (facilitates 'eco' driving),
  • Cruise control with speed limiter,
  • Electronic parking brake, etc
Ride comfort
The suspension ensures a comfortable ride thanks to the control of vertical travel. The combination of pressurised dampers at the front and bitube rear dampers enables obstacles to be soaked up smoothly at moderate speeds.

Quality cabin airThe Soft-Auto-Fast controls for the advanced, innovative triple-action climate control are intuitive to use and positioned together between the vents, while the system's automatic functions can be customized to suit individual requirements. 

Today, while the results of certain surveys have yet to be published, they all point to similar findings. Those independent surveys that have been published (JD Power, ADAC, etc.) and the results of in-house surveys and tests in the specialist media suggest that Laguna has succeeded in achieving a TOP3 ranking.
