New Renault Laguna Estate and GT sedan is powered either by a 2.0 liter turbo gasoline engine producing 205 hp or a 2.0 litre diesel dCi 180 hp extinguish. Top speed is clocked at 232 km / h for the sedan while the masses managed 222 km / h 0 to 100 kph sedan should take about 8 seconds while the mass requires about 8.5 seconds.
But more interesting than the engines on the measure is Active Drive chassis. This new chassis features a four-wheel steering system (4WS) to give the driver easy handling and steering precision. In the town of Active Chassis book a hold shorter, namely 10.80 meters, the same as the Renault Clio.
New Renault Laguna GT is scheduled to go on sale in France early next month, with the rest of Europe after this summer.
Four-wheel steering for an exceptional hike
Active Drive chassis with four-wheel steering provides many advantages, starting with improving the handling, extremely rigorous dynamic response and accuracy of driving gives the driver intuitive control on the bend line, in order to reach new heights in the conduct and active safety. Management is immediately enjoyable and reassuring, even at low speed. In town and on winding roads, the car is easy to drive: handy and precise.
Advanced roll control, with specific parameters and reinforced seat support, gave the impression that the Renault Laguna GT corners flat, without addressing in the turn. The driver was pleasantly surprised by the lack of dynamic transient phenomena in a turn, and by the extreme precision achieved by very small wheel angles. Active Drive chassis with four-wheel steering also excels in active safety, both under hard braking conditions (with a good control of adhesion asymmetric, and ESP suited to the sporty driving styles), and during maneuvers evasive high speed ( ‘elk’ test).
Impressive handling at low speed
Active Drive chassis with four-wheel steering makes Renault Laguna GT exceptionally easy to operate in the city and superbly agile on winding roads. At speeds below 60kphh, the rear wheels turn in the opposite direction to the front wheels, up to an angle of 3.5 degrees. This provides two advantages: a small turning circle, in order to facilitate the manoeuvre, and small angles flying through the more direct, specially tuned steering.
With four-wheel steering on the Active Drive chassis, the Renault Laguna GT is 10 per cent smaller than with two steering-wheel steering: 10.80 metres (the same as Clio!) With 18 – inch tires, instead of 12.05m . Most of the rear wheel steering angle, plus the turning circle. Improving the handling is especially noteworthy in tight parking situations and along the narrow streets of the city.
With the front wheels and the rear wheels turn in opposite directions, the car rotated efficiently, which means that the small steering angles are required for the same direction. Recognizing the need for a steering wheel 16 ° angle to produce a 1 ° tower in the front wheels on New Laguna, it takes only 13.5 ° with the chassis Active Drive. And that figure drops to 12 ° when the rear wheels are turned to the maximum angle of 3.5 ° in the opposite direction to the front wheels. Because the leadership is more direct, with less need for wide wheel angles, printing and handling agility is greatly enhanced. For one profile curve, the driver will require less action on the steering wheel. This makes it more efficient to avoid, with the car without apparent effort to weave around obstacles.
From 60kph, the emphasis is on the steering precision. The rear wheels turn simultaneously in the same direction as the front wheels, to enhance stability, as if the car was on rails. Active Drive System with four-wheel steering counters of the centrifugal force that tends to push the stern out round bends, and thus raises the speed cornering security. The rear axle is set to the ideal path, with a rear-wheel angle of less than 2 ° in most situations, the stability and effectiveness. Active Drive chassis with four-wheel steering enhances dynamic handling, with sound, the answer reassuring for the pleasure of driving traffic.
Unparalleled active safety
Active Drive chassis with four-wheel steering also enhances security to reassure increased during evasive action. In an emergency situation, the rear-wheel angle can climb to 3.5 °. Cut them into ESC (Electronic Stability Control), specially configured for a sporty driving style, is delayed, so that the maneuver can be done both safely and faster. ESC switches only when necessary, and is being implemented gradually, as it is synchronized with the rear-wheel turning to action. Via the ESC / ABS unit, the control unit detects 4WS situations of asymmetric braking, adjusting the rear-wheel angle turn automatically to keep the car stable without a driver action required. This helps the driver during retain control of critical situations, and peace of mind without interruption during every day driving conditions.
Dynamic logic control
Jointly developed by Renault and Renault Sport Technologies, the Active Drive chassis with four-wheel steering implements electronic monitoring of vehicle dynamics. A sensor on the steering column sends the information via the steering wheel angle CAN network to the control unit 4WD, located behind the rear axle. The control unit also inputs 4WD vehicle speed from the ESP / ABS unit. And it tracks wheel angle to detect specific information flying movements symptomatic of a sporty driving style or avoidance situation. All these parameters are analyzed to determine the tower rear wheel angle, which is implemented using an electric actuator of the rear axle. Dynamic behavior of the vehicle is modeled precisely to define the ideal path of the vehicle at any time on the basis of the driver’s input and the real situation of the vehicle. The controller and electrical supplied by Aisin, a Japanese equipment supplier known for his experience of four-wheel steering.
High performance engines
The diesel version of the Renault Laguna GT is powered by a 2.0 dCi engine, the best in its class for performance, driveability and acoustics. In this application, it yields outstanding peak power of 180hp (131kW) at 3750rpm. Maximum torque of 400Nm is available from 2000rpm, fast, consistent, sustained build-up through 5000 rpm. A low inertia variable nozzle turbocharger strengthens dynamic response at low revs to achieve superlative performance: 29.6 seconds for the 1000 metres standing start, and from 0 to 100kph in 8.5 seconds. This new device is equipped with a particulate filter and valve exhaust gas recirculation with enhanced cooling, which makes driving pleasure intense perfectly compatible with environmental protection: mixed cycle consumption Fuel is only 6.5 litres/100, resulting in CO2 emissions of only 172g/km. With its ultra-fast glow plugs, 2.0 dCi 180hp unit roared into action instantly when the Start button is pressed, even in conditions of extreme cold (up to -23 ° C).
The petrol version of the Renault Laguna GT is powered by a sporty version (205hp/150kW at 5000rpm and 300Nm of 3000rpm) of the two-litre 16-valve unit derived from the technology of Renault Sport featured on Mégane Renault Sport, and more specifically to Retravaillé Renault Laguna GT, to get the best performance, handling and intense driving pleasure. It is superbly versatile, combining velvet with surprising finesse response crisp, ideal for sports use.
Specifications such as the specific air-intake system and dual-scroll turbo ensure the rev-counter leaps forward at the slightest touch of the throttle. Renault Laguna 2.0T GT accelerates from 0 to 100kph in 7.8 seconds and takes 28s to cover 1000 metres from the stop. Nevertheless, the fuel consumption is very reasonable 8.2 litres/100km, which makes for CO2 emissions by only 194g/km.
Distinctive GT styling
With its distinctive streamlined profile, Renault Laguna GT expresses an elegance that goes much further than sporting aptitude alone. The long plunging bonnet terminates in a highly assertive front-end with a radiator grille characteristic of the most powerful Renaults. Purposeful- looking lateral air-intakes suggest an insatiable appetite for the open road, corroborated by the wise gaze of the headlamps against the neat black background. Renault Laguna GT is fitted with generously sized 225/45 18-inch special high performance Bridgestone Potenza tyres, a Formula One spin-off, mounted on special Celsium wheels. The highly efficacious braking system uses 320mm diameter discs at the front and 300mm discs at the rear. Aerodynamic sills reflect the promise of the Active Drive chassis extend from the front of the car to the characteristic straight-section twin tailpipe at the rear. Sports tourer attributes run through to every last detail, such as the gloss black wing mirrors and smoked rear lamp units.
As well as appearing on the outside centre pillar, the exclusive GT logo is also embossed on the light grey alcantara of the front seatbacks. As on all Renault Laguna models, the interior design exudes a most impressive sense of comfort and quality, in all seats. Sports design details abound, highlighting the exclusive capacities of the GT version: special three-spoke leather sports steering wheel with grey stitching, cross-drilled aluminium pedal, sports gearshift lever knob, dark charcoal Riviera leather upholstery with reinforced lateral support. Extreme attention has been paid to materials and finish, true to the car’s unwavering commitment to pure motoring pleasure.
Equipments and technology
The Renault Laguna GT range starts with the Dynamique equipment level and features a long list of top-end equipment selected to favour travelling comfort, including a three-mode (Soft/Auto/Fast) dual-zone automatic climate control system complete with toxicity sensor and automatic air recycling. Driving comfort is enhanced by the availability of parking brake assist, cruise control with speed limiter and automatic headlamp and wiper activation, while acoustic comfort was dialled into the model from a very early phase in its development thanks to features that have made Renault Laguna a benchmark in this area, too. Nothing has been left to chance on the active and passive safety fronts either. Renault Laguna and the GT version particularly excel in terms of their active safety performance as demonstrated by the latest EuroNCAP test results. Its principal innovation concerns improved side impact protection thanks to a twin impact sensor system and new-generation double thorax/groin airbags.
The affordable overall equipment and performance package of this flagship version sets it apart on the sports saloon marketplace and ensures the ultimate in reassuring driving pleasure.
Advanced technology for an unforgettable ride
Four-wheel steering systems of the 1980s were essentially mechanical, with the front and rear wheels linked and pre-determined angles aimed at making up for shortcomings in the vehicle’s handling (e.g. a tendency to understeer). Such systems were gradually superseded by the advent of ESP. Meanwhile, towards the end of the 1990s, carmakers like Nissan were beginning to develop solutions based on electrically- and even hydraulically-operated activators with a view to taking the dynamic performance of their vehicles forward. Electronic control of the rear wheels has enabled handling to be fine-tuned even further, notably in the case of rear-wheel drive vehicles.
The Active Drive system builds on this approach by ensuring a more dynamic and more reactive response to make the absolute most of the inherent qualities of Renault Laguna GT’s remarkable chassis and consequently deliver even greater driving enjoyment. In addition to the complex modelling of the vehicle’s handling, real-time response to the driver’s instructions (every 10ms) and its ability to adapt to different conditions, New Laguna GT’s Active Drive four-wheel steering system means that active safety systems are only required as a very last resort, which means drivers benefit from more efficient and even more reassuring reactions when faced with an unexpected driving situation.
