· The engine delivers outstanding performance. Maximum output is 221kW (300PS) at 6,200rpm; maximum torque is 353N-m (36.0kg-m) at 5,000rpm. And yet it is more compact than the previous engine: 36mm narrower and 61mm shorter. Magnesium cylinder head covers and a two-piece aluminum die-cast intake manifold help make the engine lighter as well.
· The Japanese Ministry of Land, Infrastructure and Transport has certified the new Legend as an Últra Low Emissions Vehicle. Its emission levels are 75% lower than those required by 2005 standards. ( posted on conceptcarz.com)
· The fully dual exhaust system splits into two pipes immediately after the under-floor catalytic converter. Independent exhaust pre-chambers have also been added to achieve significant flow enhancement while contributing to quieter operation. The variable-flow mufflers combine quiet operation at low rpm’s with powerful output at high rpm’s.
· DBW (Drive By Wire) electronic throttle control optimizes throttle characteristics in accordance with vehicle speed, providing the driver greater control. An organ pedal integrated with the DBW provides a linear pedal feel by positioning the pedal fulcrum close to the heel of the foot.
Electronically controlled 5-speed Sequential SportShift automatic transmission
· A more compact 5-speed automatic transmission takes full advantage of the engine’s superior performance. Gear ratios have been set to deliver responsive off-the-line and acceleration performance, as well as economical cruising. Shift control is smooth and faithful to the driver’s intent, with minimal gear change shock.
· Honda’s Prosmatic transmission control technology, which provides intelligent shift control in response to driving conditions, has further evolved, with a new shift hold control that reduces unnecessary gear changes.
· Complementing the Sequential SportShift automatic transmission, the gun-grip shift knob provides easier gear changes and a sporty image. The new Legend is also equipped with paddle shifters that allow the driver to enjoy a more sporty, manual transmission feel, changing gears without taking hands off the steering wheel.
Drive System
SH-AWD Super Handling All-Wheel-Drive system
· A world’s first, the SH-AWD system combines front-rear torque distribution control with independently regulated torque distribution to the left and right rear wheels to freely distribute the optimum amount of torque to all four wheels in accordance with driving conditions. Front-rear torque distribution varies between ratios of 30:70 and 70:30, and lateral torque distribution in the rear wheels varies between ratios of 100:0 and 0:100. Torque is used not only for propulsion, but for cornering as well, resulting in a significant enhancement in vehicle maneuverability.
· The system’s torque control logic operates primarily on active feed-forward control based on driver input. This is combined with feedback control based on vehicle behavior to achieve highly precise control that respects the driver’s intent.
CFRP (carbon fiber reinforced plastic) propeller shaft
· The propeller shaft transmitting torque to the rear wheels is made of CFRP (carbon fiber reinforced plastic) for reduced weight.
Chassis and body
The newly developed chassis combines outstanding levels of driving performance with a luxurious ride.
· The front double-wishbone suspension provides outstanding straight-line stability and ride comfort.
· The rear multi-link suspension, composed of an upper arm, two lower arms, and a control arm, combines stability with superior comfort.
· Large-diameter front ventilated disc brakes are combined with large-diameter rear ventilated drum-in-disc brakes. To save weight, both the front and rear calipers are made of aluminum, with high-rigidity, opposing 4-pod calipers used in the front.
· The body has been made approximately 33% more rigid overall compared to the previous model, with approximately 34% higher bending rigidity and 30% higher torsional rigidity. Front-rear rigidity balance has also been enhanced and welds strengthened throughout to achieve higher rigidity.
· Front-rear lift balance has been optimized, with lightweight aerodynamic parts employed on the vehicle’s underside. A flush surface design has been applied throughout, including elimination of level differences around the side windows and repositioning and reshaping of the wiper blades, to achieve a Cd value of 0.29*.

Weight Reduction Technologies
Since strong, lightweight, high-tensile steel is used in some 50% of the body frame’s main structural components, the body is approximately 19kg lighter than if conventional materials were used.
· The sub-frame employs a hybrid construction. Members formed from aluminum pipe using an innovative blow molding process are welded to cast members to achieve significant gains in both lightness and rigidity. This saves approximately 19kg in weight compared to the use of cast members.
· The lower arms in the front and rear suspensions and the front and rear bumper beams are made of aluminum with a new manufacturing process which helps save weight and increase rigidity.
· The hood, front fenders, and trunk lid are made of aluminum using high-speed blow molding that enables one-piece molding of complex shapes, with approximately ten times the stretching capacity of conventional presses.
· Higher engine output and various weight reduction measures combine to significantly improve the new Legend’s power-to-weight ratio, for outstanding acceleration performance. As compared to the previous model’s 7.86 kg/PS, the new Legend achieves an impressive 5.87kg/PS.
Quietness
· Fluid-filled mounts are used for the engine and transmission mounts, and the front and rear engine mounts are electronically controlled. Further, the front sub-frame is supported by a floating bracket with the engine mounts attached to it using a double anti-vibration mechanism to more effectively absorb engine vibration.
· Noise reduction technologies such as Active Noise Control, which sends an opposite phase signal through the car’s audio system to cancel out engine hum to ensure a quiet ride. The target frequency is identified based on engine speed, and microphones mounted in the front and rear roof monitor conditions. Sound is emitted from the car’s audio system as required to cancel out noise and reduce engine hum.
· Lightweight, high-performance sound-absorbing materials are employed in the carpet, dashboard insulator, roof lining, and trunk compartment lining. Lightweight sound absorbing materials are used wherever possible, resulting in quieter operation with only one-third the weight of conventional materials.

· The instrument panel features three-dimensional, self-illuminating gauges, backed by blue-gradation dials that are illuminated by indirect-illumination LED.
· The multi-functional display beneath the speedometer provides the driver with a range of information, including fuel consumption, average vehicle speed, and other driving details, including the operating status of the SH-AWD system.
· Blue illumination from a series of small lamps imparts an elegant touch to the interior.
Últra-high-gloss exterior finish for deep contrast and a spectacular shine
· Conventional single clear-coat finishes involve a prep coat applied using electrodeposition, followed by a first intermediate coat, a second intermediate coat, a base coat, and a clear coat. The new Legend goes beyond this standard and has an ultra-high-gloss exterior finish. Specialists painstakingly water-polish the surface after the intermediate coats are applied to make it smooth, then apply two coats of clear finish. Increasing the thickness of the clear coats creates a deep contrast that shows off all six body colors beautifully.
Genuine wood paneling made by TENDO CO., LTD. imparts the high-quality feel unique to natural wood (Exclusive Package)
