The 2010 Lexus IS 250 C And Lexus IS 350 C Luxury Hardtop Convertible Coupes

(TORONTO) – Canadians who know that perfect summer days are few can pursue more perfect moments in the open air in the all-new, 2010 Lexus ISC luxury hardtop convertible coupe. Built upon the proven platform of the popular Lexus ISseries luxury sport sedans, and engineered for no-compromise quiet and comfort, the Lexus IS250C and Lexus IS350C deliver top-down driving pleasure in good weather plus the comfort of a seamlessly-designed hardtop roof when things turn stormy.

Lexus introduced the IS sedan almost a decade ago, and it continues to deliver adrenaline-fueled moments of pure driving pleasure. Last year, the IS F joined the series as “the Beast” that delivers raw track-proven power and performance. Now, the all-new 2010 Lexus IS 350C and IS 250C hard-top convertibles give Lexus a coupe and convertible in the entry luxury segment for the first time. The IS series has become the perfect trilogy of fun, performance and freedom.

“From the heart of the aspirational luxury IS series, Lexus wanted to provide guests with a no-compromise entry luxury convertible with its own distinct design and engineering. Our guests told us they wanted a new type of convertible – one that addressed the problems commonly associated with drop-tops such as excess noise, vibration, harshness and turbulence, ” noted Larry Hutchinson, Director of Lexus in Canada. “With the ISC, Lexus delivers – with class-leading low wind noise levels, minimal turbulence and comfort characteristics we addressed their wants.”

Featuring a convenient single-switch operation, the new three-piece hardtop provides open-air freedom with the top down without sacrificing the quiet and comfort of a coupe. Constructed primarily of lightweight aluminum, the hard top also provides surprising storage space but with low noise and increased security not typically found in soft-top convertibles. In addition, the top completely retracts with no elements remaining in view.

“The ISC provides additional moments to inspire and delight our guests. These include the fastest retractable hardtop in its class – converting the ISC from an all-weather performer to an open air cruiser in just 20 seconds – plus many other features that redefine open top motoring comfort in a coupe,” Mr. Hutchinson continued.

The 2010 Lexus IS250C and Lexus IS350C are arriving at Lexus showrooms across Canada now. Pricing for the IS 250C starts at an MSRP of $52,100, while the IS 350C starts at an MSRP of $60,400.

Product Details

Sophisticated Retractable Hardtop Convertible

The Four-link roof assembly, also made of aluminum for a lightweight design, provides smooth even movement. Engineered to operate in an easy, efficient manner, each component is motor driven with detection switches, allowing the control unit to know their exact position at all times. In addition to the two main roof panels being constructed of light-weight aluminum, the back window’s reinforced glass construction also lends itself to reduced weight. Weather-strip changes in areas around the doors and windows ensure tight seals.

A roof-speed brake-control system decreases the roof speed especially as it approaches the end of the closing operation in either direction, ensuring an elegant and quiet movement. Standard Intuitive Park Assist (IPA) will stop the movement of the luggage door at the start of operation if it detects an obstacle will interfere. Also, a visual warning will appear on the instrument panel if a detected obstacle may soon interfere with top operation.

When the IS convertible’s top is opened or closed, the power windows will automatically lower if in the closed position, and raise back up when the operating switch is held. Also, when the top is up, the door windows automatically lower 15 mm when the door opens, and then raise back into a fully closed position when the door closes. This ensures the doors’ clean open/close function while also maintaining a tight seal around the glass. The aluminum hard top features an automatic front lock assembly that provides the interior security not found in soft-top convertibles. When the top is stowed in the down position in the rear of the IS convertible, the lock assembly is engaged to keep the panel in a fixed, stable position.

Convertible Aerodynamics
The IS convertible has a best-in-class 0.29 drag coefficient (Cd). This is accomplished with the help of underbody covers below the engine (with aerodynamic steps), the full floor, and fuel-tank covers, as well as a rear-floor diffuser with vertical fin and airfoil. Other areas that contribute to the low Cd include the design shape of the outer mirrors, high-mount stop lamps, and the rear tailamps. Fender fairings before the front and rear tires reduce airflow into the wheel house, improving aero characteristics and reducing air turbulence.

The IS convertible’s air conditioning system automatically adjusts for the outside temperature when the top is lowered, improving interior temperature consistency and comfort. The system adjusts the air outlets, temperature and air flow exiting the outlets. The airflow volume adjusts to outside temperature and vehicle speed, while the temperature control adjusts to outside temperature, amount of sunlight and vehicle speed. The system also includes a pollen filter and variable-control compressor.

Convertible Body Rigidity
The IS convertible’s body structure has excellent rigidity and strength, achieved by effective structural changes and additions to the existing IS sedan platform. Additional bracing was implemented to help provide excellent handling control, ride comfort and body durability while also minimizing weight gain.

Areas that received modifications or additions include the rocker area; A and B pillar under structure; side collision crossmember, and upper and rear-floor crossmembers. In addition, underfloor braces were added both in the front and the rear.

The transformation to a convertible also required reevaluation of noise, vibration and harshness (NVH) characteristics in order to meet Lexus standards. All body and chassis revisions have gone through extensive testing to ensure that the IS250C and IS350C have nearly identical NVH characteristics as the IS sedans. High-rigidity damping materials and asphalt sheets have been added to minimize vibration effects. Redesigned rear-suspension-mount bushings help reduce noise and vibration associated with the changes in body characteristics from a sedan to a convertible. Additional sound absorption and insulation materials have been optimally positioned to create a quiet, comfortable cabin.

Dual-Mode Redesign
The IS250C and IS350C’s new exterior design has its lineage in the IS sedan but possesses its own dynamic styling, including unique characteristics when interchanging between convertible and coupe configurations. With the exception of the hood, all other body panels have been redesigned to blend seamlessly with the new three-panel folding roof.

The convex shoulder lines distinguish the convertible’s profile, while the top-up configuration provides a sweeping cabin silhouette. With the top down, the belt-line draws up around the rear deck lid, providing a muscular look.

In the front, hood lines flow into a unique chrome grille shape, then continue down into an air inlet before flowing outward past the more distinctive elliptical fog-lamp design.

The rear view features a clean, continuous design, with flowing bumper corners and a strong bumper shape that flows inward towards the exhaust. All-new combination tail-lamp clusters feature LED lights and two distinct horizontal lines that emphasize breadth, while the LED brake light integrated within the standard rear spoiler imparts a sporty impression.

The IS convertible features 18-inch wheels which have an athletic five-spoke design with asymmetrical changes in shape and a liquid-graphite finish. They feature the tire-pressure warning system found on the sedan models. In addition to standard all-season tires, an optional run-flat tire is available either with or without a spare, adding to the available luggage space.

Five colours common with the IS sedan are available on the convertible, including ultrasonic blue which is shared with the ISF. Like the sedans, additional wet sanding is applied in mid-coat application to provide a premium finish.

Unique Interior Look
The IS convertible interior maintains the luxury touch points associated with the IS sport sedans, while new comfort and entertainment features provide a consistent atmosphere regardless of top configuration. Special attention was given to providing an attractive interior design when viewing the convertible externally. The door and side trim is fashioned to create continuity and continuous flow from front to back.

A four-seat configuration provides each passenger with their own comfort space, and the rear-seat console enhances the rear-passenger amenities with cup holders and storage. Soft padding on the sides of the console and the outer trim areas improve comfort. The rear headrests are retractable for improved visibility and the lever can easily be accessed from the rear console or from the driver’s seat. Rear-seat comfort is enhanced by shifting seat position inboard, providing for sizeable headroom.

Eight-way adjustable power front seats, including power lumbar support are standard, and the available heated/ventilated function has increased heating range to include the shoulder areas and increases airflow in ventilation function. Front-seat backs are scaled inward, and slim, leather seat-back pockets help to maximize rear-seat legroom.

The gauge cluster is similar to that of the IS sedan, some additions on the IS convertible add style and function. A higher-contrast multi-information LCD, dial-color change for more contrast, and decreased surface-glass transmittance all enhance visibility when the top is down. The multi-information display also includes status of the hardtop while in transformation, providing a bar graph showing its progress. It also displays a warning to inform the driver if the roof is not completely open/closed, a rear obstacle may impede proper open/close operation, or if the open/close function is not available while the vehicle is in motion. Metallic trim around the two main gauges contribute to a premium look.

The interior adopts recycled materials in 13 various areas including door and side trim. The IS convertible will have three interior trim color options, including two new colour combinations. In addition to black leather interior, a new alabaster color is joined by a distinctive alabaster/blue contrast trim.

Dynamic Driving Performance
The IS250C and IS350C provide a consistent blend of driving performance and comfort in either convertible or coupe configuration. They share common double-wishbone front and multi-link rear suspension systems with the IS sport sedan models.

The double-wishbone front suspension received a number of changes to provide the handling stability and ride comfort required for a convertible. The torsional rigidity of the suspension bushings was optimized, as was the spring constant on the coil springs, and the shock absorber damping force. The stabilizer shape and the Electric Power Steering (EPS) gear ratio were also revised to help provide improved control.

The multi-link rear suspension also received similar changes to suspension bushings, coil springs and shock-damping force. In addition, the rear-suspension tower was lowered with enhanced rigidity to help provide rear control and linear yaw response; it also provides improved trunk space.

Performance Oriented Drivetrains

The IS convertible models feature the same powertrains as the IS sedans. The IS 350C's 3.5-litre V6 delivers exhilarating performance with outstanding 306 horsepower at 6,400 RPM along with 277 lb.-ft. of torque at 4,800 rpm. The IS 250C's 2.5-liter V6 engine has a great combination of fuel efficiency and performance. The IS 250C’s V6 produces 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. Both engines utilize aluminum cylinder blocks and heads, while employing dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.

A direct-type fuel-injection system provides a cooling effect in the cylinders, enabling the high compression needed to extract maximum energy from the fuel. Aside from its larger displacement, the 3.5-liter V6 differs chiefly in that it augments the direct fuel injection with port fuel injectors. In light- and medium-load conditions, these additional injectors help produce a precise burn, increasing power and efficiency, while reducing emissions. A dual exhaust system reduces backpressure at higher engine speeds. Like IS sedans, the IS250C and IS350C meet Tier 2 Bin 5 emissions

An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350. The IS 250 comes with either a six-speed manual transmission or the paddle-shift, six-speed automatic transmission.
Easy Access Utility & Comfort
The new IS convertible emphasizes easy access and rear-seat comfort. In addition to front doors that are 11.8 inches longer than the IS sedans, two convenient fold-forward lock-release levers are standard on both sides of the front passenger seats, making it easier to operate from any location inside the vehicle. In addition, the passenger seat features a power slide button on the top of the seatback to ease rear seat ingress/egress. A standard new automatic one-touch, easy-entry power-seat mechanism provides even easier egress and ingress through quick-acting, front-seat fold-and-slide activation. The two passenger doors also have three open-stopping positions (rather than the normal two) to add convenience in various parking situations with different spacing between vehicles. The IS C also is equipped with a standard power tilt and telescoping steering column to help the driver quickly get into a comfortable position.

Standard Intuitive Park Assist (IPA) system uses ultrasonic sensors to detect objects close to the car's front and rear bumpers, alerting the driver and showing distance to objects in the multi-information display within the speedometer. When any IS model is also equipped with the optional navigation system, information on objects detected in the rear are shown in greater detail on that system's seven-inch display via the backup camera.

Standard Hill-start Assist Control helps prevent the vehicle from moving backward when the driver moves their foot from brake pedal to the accelerator. The system will also be available for the first time with the manual transmission.

The standard Lexus Premium Audio System features a six-disc, in-dash CD changer, and eight speakers. An equalizer system maintains the same acoustic field when the top is either open or closed, compensating for the natural loss of bass sounds when open. In addition to the 1/8^th-inch audio mini jack on the IS sedan, the IS convertible will also have a standard USB connector in the centre console for interface with an iPod that will not only play the music on the device, it will display information on the navigation screen such as artist, album and song track.

Bluetooth Audio wireless connectivity is another new feature available for those customers with compatible devices. Standard XM satellite radio (subscription required) offers a wide variety of programming, while standard hands-free voice recognition and Bluetooth technology for models without optional navigation allow phone calls to be made and received while driving.

Lexus’ latest Hard-Disk Drive (HDD) navigation system, with a new set-up display and increased audio-display tabs, is available on the IS convertible and is complete with a seven-inch VGA touch-screen and back-up camera.. The navigation system also includes as standard on all navigation-equipped IS convertibles Lexus’ latest voice recognition system, Voice Command, which builds upon the previous-generation system’s functionality, adding more spoken-command flexibility. With Voice Command users avoid having to speak commands in a specific order (e.g., “Phone > Dial by Name > Dial Bob”). Now this same task can be completed simply by saying, “Call Bob at home.” The Voice Command system also works to control many functions of the audio system, heating and air conditioning, and the navigation system. Commands such as, “Make it cooler,” “Let’s find XM channel 46,” “Show me Japanese restaurants,” and “I need a gas station,” make tasks easier to accomplish, in fewer steps, and help allow drivers to focus more on the road ahead. A Mark Levinson Premium Surround Sound Audio system, exclusive to Lexus is available in conjunction with the optional navigation system. This 12-speaker audio system features discrete 5.1 multi-channel playback with 5.1-channel speaker architecture. Its 10 amplifier channels provide 270 watts total output at 0.1 percent total harmonic distortion (THD). From 20-20,000hz, the Mark Levinson system plays conventional CDs and specially encoded DVD audio and DVD video discs, plus MP3/WMA-formatted CD-R/RW and DVD-R/RW. DVD movies can be viewed on the optional navigation system's seven-inch colour touch screen when the parking brake is engaged.

Lexus Safety & Security
Standard Vehicle Dynamics Integrated Management System (VDIM) governs all of the vehicle’s dynamic handling systems – the Anti-lock Braking System (ABS), Brake Assist, Vehicle Stability Control (VSC) and Traction Control (TRAC) – employing them collectively and seamlessly to make corrections while helping provide higher dynamic capability. VDIM also interfaces with the electronic throttle control system.

The IS convertible features large, ventilated four-wheel disc brakes with Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist. The IS350C is equipped with 13.15-inch front and 12.20-inch rear rotors with aluminum four-piston front calipers to aid in heat dissipation and stopping power and reduce unsprung weight. The IS250C has 11.65-inch front and 12.20-inch rear rotors.

Passive-safety technology begins with a number of body-structure changes integrated in the IS250C and IS350C to help augment strength and torsional rigidity. Seatbelt pre-tensioners and force limiters are used for the front seats, while the rear seats adopt emergency locking retractor seatbelts with an automatic locking retractor.

In addition to the dual-front airbags, the Lexus Supplemental Restraint System (SRS) for the IS convertible includes new enlarged front-seat-mounted head and torso side airbags, and knee airbags for both the driver and the front passenger. The front-passenger airbag features two chambers, creating an indentation in the center impact area that helps to provide overall occupant protection.

The standard High Intensity Discharge (HID) headlamps paired with the Adaptive Front-lighting System (AFS) helps to illuminate a curve as the driver steers into it.

The standard SmartAccess keyless entry and push-button-start/stop allows the driver to keep the access key FOB in a pocket or purse. The standard HomeLink programmable garage door opener also operates home security devices and other systems.

F-Sport Performance Accessories Available for IS C
The IS C F-Sport Performance Accessories will include performance enhancing parts such as 19-inch forged alloy wheels, brake upgrades, suspension systems, air intake, exhaust systems and more. F-Sport Performance Accessories by Lexus USA are engineered by Toyota Racing Development (TRD). When installed by an authorized dealer, the accessories are fully warranted for 12 months or for the balance of the new car warranty, whichever is greater. Parts for the IS C will be on sale upon the IS C’s launch.
