TURBOCHARGED LEXUS LF-NX CONCEPT

• New Lexus LF-NX Turbo compact premium crossover concept debuts at Tokyo motor show
• New variant of the original LF-NX concept presented at the Frankfurt motor show
• Powered by a 2.0-litre four-cylinder turbocharged engine, Lexus’s first turbo petrol unit
• Driver-focused cockpit

Following the unveiling of the LF-NX HV compact premium crossover concept at this year’s Frankfurt motor show, a new version – the LF-NX Turbo- is making its world debut today in Tokyo.

Combining spirited performance with fuel efficiency, the new LF-NX Turbo’s 2.0-litre engine paves the way for the introduction of turbocharged petrol powerplants in future Lexus models.

Design

The LF-NX Turbo shares the innovative, striking design of the HV (hybrid) version that was presented earlier this year in Frankfurt, with the addition of numerous detail changes to the exterior and interior that reflect the performance potential of its new 2.0-litre turbo engine.

The revised frontal treatment sees the Lexus spindle grille gain a smoked chrome trim and the addition of a narrow, black mesh lower air intake above a matt chrome chin spoiler. The effect is to reinforce the crossover’s lower centre of gravity and sportier performance.

The wheel arches and lower rocker panel have a high-gloss black paint finish and the upper rocker panel moulding is finished in matt chrome. The smoked chrome effect of the grille is repeated in the glazing surrounds and the upper surface of the door mirrors.

At the rear, a new lower bumper design is underscored by a full-width aerodynamic diffuser with a matt chrome finish. This is flanked by highly sculpted chrome exhausts, shaped to echo the styling the of the vertical air intakes in the front wings.

The concept gains a stronger alloy wheel design and a change in tyre size, replacing the HV’s 255/50R20 rubber with 255/45ZR20, giving the vehicle a more sporting appearance with a wide, confident stance.

In the cabin the performance potential is expressed in the red illumination for principal controls, meters, navigation screen and Remote Touch Interface, touch tracer and touchpad controls.

Powertrain

The LF-NX Turbo concept is equipped with Lexus’s first turbocharged petrol engine.

The 2.0-litre, four-cylinder unit features Lexus’s advanced high-tumble port, fan spray fuel injection, D-4S and VVT-i combustion technologies. Its design sees the exhaust manifold integrated into the cylinder head, and it is fitted with a twin-scroll turbocharger with an active wastegate valve.

By optimising the exhaust gas temperature, the exhaust manifold delivers high performance, fuel efficiency and low exhaust emissions, while the turbo operates effectively across the widest possible rev range.

The unit is engineered for fast throttle response, yet demonstrates excellent fuel economy.

 

LEXUS UNVEILS NEW RC COUPE

• Concept-to-reality coupe that takes Lexus into new territory
• Development focus on body rigidity to secure agile handling
• High-performance V6 petrol and hybrid powertrains that accentuate the RC’s sporting nature
• New Lexus styling direction in a dedicated coupe, including the strongest interpretation yet of the trademark Lexus spindle grille
• New development of Lexus Remote Touch Interface control system

Lexus today unveiled its new production-ready RC coupe at the Tokyo motor show, a car designed to raise awareness of the brand with a wider audience and imbue it with even stronger emotional appeal.

RC is part of a ride and handling revolution at Lexus, something which began with the latest-generation GS and gained further momentum with the launch this of the new IS. Although it’s built on the GS platform, the RC is not simply a two-door derivative of a saloon, but differs in all its dimensions from the GS and IS.

Two versions were revealed: the RC 350, with a 3.5-litre V6 engine teamed with an eight-speed sequential transmission; and the RC 300h hybrid, with a 2.5-litre petrol unit.

Chief Engineer Junichi Furuyama, who also leads the IS programme, said the aim is for the RC to engage with owners on an emotional level: “One of the main reasons motoring enthusiasts aspire to own coupes is that they look cool, sexy even. We developed the RC to deliver the kind of extra responsiveness that drivers find exhilarating, not overwhelming, true toomotenashi – the traditional Japanese spirit of hospitality.”

Mark Templin, Executive Vice President Lexus International, said: Our focus is to strengthen the brand’s emotional appeal through our products and the RC is another demonstration of this.

“The emotional attachment people make with a coupe is rooted in purity of design and the driving experience. With the RC our engineers have got that balance right.”

Exterior design

The designers have endowed the RC with deeply contoured lines and crafted the widest and lowest-set interpretation yet of the Lexus spindle grille.

In terms of size, it occupies a unique position in the Lexus range, measuring 30mm wider, 35mm lower and 70mm shorter in the wheelbase than the IS saloon, giving it a classic coupe stance.

Triangular headlamps capture the sporty characteristics of the earlier LF-LC concept, along with the novel three-lamp LED configuration that was part of the show car’s design. Both front and rear lighting units use the Lexus L design motif.

The aluminium wheels further express the concept-to-production design philosophy, with two designs: a deeply sculpted, 10-spoke 19-inch wheel and a muscular, five-spoke 18-inch version. Both are precision-machined and finished with elegant black and platinum caps.

The hero colour for the RC is red, with a new Lexus painting process giving brighter and stronger contrasts through using multiple layers of clear and deeper-coloured coating.

The RC measures 4,695mm long, 1,840mm wide and 1,395mm high, with a 2,730mm wheelbase.

Interior design

The four-seat interior of the RC is strongly influenced by Lexus’s sports concepts, reflected in the extensive use of contrasting colours, materials and lighting.

The purpose-designed lighting package gives a sense of occasion, with illumination that reflects upwards rather than down to envelop the cabin.

The high-contrast interior colours emphasise the elegant lines around the interior, together with shimamoku highlights – a genuine wood finish created using an intense layering technique refined by Lexus.

The driver’s cockpit follows the established Lexus design principle of an upper operation zone and lower display zone. The upper zone houses the instrument panel and seven-inch navigation screen; lower down the layered centre console integrates the Remote Touch Interface controller.

The seats are made using an integrated foaming construction, similar to the moulding technique used for racing seats, to provide excellent comfort and support.

Driving dynamics

The RC’s strong and purpose-built chassis represents the latest stage in Lexus’s missions to deliver a world-class driving experience, building on the advances made with both the latest GS and IS models.

Extra-thick underbody rocker panels greatly increase the car’s rigidity and enhance its driving performance. Lexus has also used new manufacturing techniques it pioneered in the LS and IS models, including the use of innovative body adhesives, to strengthen the chassis.

Aerodynamic aids, especially those featured on the RC’s underbody, also contribute to the handling package. The suspension design features front double wishbones a multilink system at the rear.

Powertrains

The RC V6’s specific output per litre is second only in the Lexus range to the LFA. The dual-injection 3.5-litre petrol unit produces a maximum  314bhp (234kW) at 6,400rpm and peak torque of 380Nm at 4,800rpm.

The eight-speed Sports Direct Shift transmission with paddle shift controls is adapted from that used previously in the IS F, optimised for power delivery and economy. In M (manual) mode, full torque converter lock-up from second to eighth gear allows for downchanges in just two tenths of a second.

The hybrid – the first Lexus hybrid coupe – uses a dual-injected 2.5-litre four-cylinder petrol engine with a 141bhp (105kW) electric motor driven through an electronic continuously variable transmission (E-CVT) with a shiftmatic function providing six step-gears.

According to market, RC will be offered in front-wheel or all-wheel drive configuration. Further details of European powertrain line up will be announced in 2014.

The sound generated by the engine has been specially tuned to add to the coupe driving experience.

Advanced technologies

Advanced technology features in the RC include an upgraded version of Lexus’s Blind Spot Monitor and a new iteration of the Remote Touch Interface controller.

The RC will be the first model to be fitted with the improved Blind Spot Monitor, capable of detecting vehicles approaching from behind at a higher speed and from a greater distance than before.

Lexus’s innovative Remote Touch Interface for controlling audio and navigation systems has been revised, improving the overall tactile reaction that is all part of the engaging driving exerience.
