The sophisticated Lexus IS 250C and IS 350C continues to blend the expressive stylishness of a hardtop convertible with the quietness and comfort of a coupe. The IS convertible’s quickly goes from a hardtop to a convertible in less than 21 seconds. The IS 250C and IS 350C’s exterior design has its lineage in the IS sedan but possesses its own dynamic styling, with unique characteristics coming to life when interchanging between convertible and coupe configurations.
The convertible’s three-piece hardtop provides open-air freedom with the top down through the operation of a convenient single switch. Constructed primarily of lightweight aluminum, the hardtop provides surprising storage space, with low noise and increased security not typically found in soft-top convertibles. The top completely retracts with no elements remaining in view.
The four-link roof assembly, also made of aluminum for a lightweight design, provides smooth, even movement. Each component is motor driven with detection switches, allowing the control unit to know their exact position at all times. The back window’s reinforced glass construction lends itself to reduced weight.
A roof-speed brake-control system decreases the roof speed as it approaches the end of the closing operation in either direction, ensuring an elegant and quiet movement. On models equipped with available Intuitive Park Assist (IPA), sonar sensors in the rear bumper 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. 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. The aluminum hardtop features an automatic front lock assembly that provides the interior security not found in most 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.
The optional Pre-Collision System (PCS) is packaged with Dynamic Radar Cruise Control, which uses millimeter-wave radar to measure and help maintain a pre-set following distance from a vehicle traveling ahead. PCS relies on the radar sensor to detect certain obstacles in front of the car, and a PCS computer with sensor inputs from vehicle speed, steering angle and yaw rate is designed to determine whether a collision is unavoidable. In such a situation, PCS alerts the driver via sound and visual warnings while preemptively retracting front seat belts and pre-initializing Brake Assist (BA) so that increased braking will be applied the instant the driver depresses the pedal.

Safety and Security Features
- The body structure has excellent rigidity and strength, achieved by effective structural changes and additions to the rocker area, A and B pillar under structure, side collision crossmember, and upper and rear-floor crossmembers; underfloor braces were added both in the front and the rear.
- All body and chassis revisions went through extensive testing to ensure that the IS 250C and IS 350C have nearly identical noise, vibration and harshness (NVH) characteristics to the IS sedans.
- High-rigidity damping materials and asphalt sheets were added to help minimize vibration effects, while redesigned rear-suspension-mount bushings help reduce noise and vibration associated with the changes in body characteristics from a sedan to a convertible.
- The IS convertible features standard 10-spoke 17-inch wheels with a clean liquid-graphite finish and optional split five-spoke 18-inch wheels with a liquid-graphite finish and all-season tires.
- Engineers tuned and optimized specific features including:
- The double-wishbone front suspension to help provide handling control and ride comfort;
- The torsional rigidity of the suspension bushings,
- The spring constant on the coil springs, and the shock absorber damping force;
- The stabilizer shape and the Electric Power Steering (EPS) gear ratio for control;
- The suspension bushings, coil springs and shock-damping force of the multi-link rear suspension; and
- A lowered rear-suspension tower with enhanced rigidity to help provide rear control, linear yaw response and improved trunk space.
- Standard Vehicle Dynamics Integrated Management System (VDIM) governs all of the vehicle’s dynamic handling systems – the Anti-lock Braking System (ABS), Brake Assist (BA), Vehicle Stability Control (VSC) and Traction Control (TRAC) – employing them collectively and seamlessly to make corrections while helping provide higher dynamic capability; and interfaces with the electronic throttle control system.
