Lexus is expanding its LC 500 sports car family with a soft-top convertible that will be celebrating its world premiere at the 2019 Los Angeles Auto Show on Wednesday.

Set to go on sale next summer, the model closely echoes the coupe but adopts a four-layer soft top that has been designed to recreate the flowing roofline of the coupe.  It can be opened or closed in approximately 15-16 seconds at speeds up to 31 mph (50 km/h).

The top will be offered in black and beige, and be paired with a stylish body in one of ten colors.  Speaking of the latter, the convertible features a unique rear end with a new tonneau cover and a modified trunk with an integrated third brake light.

Since owners will drive their cars in a variety of conditions, the LC 500 has been equipped with an advanced heating and cooling system.  Dubbed Lexus Climate Concierge with Upper Body Heating, the system automatically adjusts the climate control system, seat heaters, neck heaters and heated steering wheel to ensure occupants are comfortable regardless of the outside temperature.

Speaking of comfort, the convertible has a specially designed beltline and rear molding which help to reduce wind noise.  There’s also a transparent wind deflector and an optional wind screen that reduces buffeting at high speeds.

Inside, drivers will find a stylish cabin with leather and Alcantara upholstery.  Other highlights include alloy pedals, an ambient lighting system and a 10.3-inch infotainment system with Android Auto, Amazon Alexa and Apple CarPlay compatibility.

The convertible comes standard with the Lexus Safety System+ which includes a Pre-Collision System with Pedestrian Detection, Lane Departure Alert with Lane Keep Assist and All-Speed Dynamic Radar Cruise Control.  There’s also Intelligent High Beam Headlights and a Blind Spot Monitor with Rear Cross-Traffic Alert.

Lexus didn’t release detailed performance specifications, but the convertible has a 5.0-liter V8 engine that produces 471 hp (351 kW / 478 PS) and 398 lb-ft (539 Nm) of torque.  It is connected to a 10-speed automatic transmission that sends power to the rear wheels.

While there’s no word on weight or 0-60 mph (0-96 km/h) times, the automaker beefed up the chassis and fined tuned the suspension.  In particular, the rear has a die-cast aluminum suspension brace and a performance dampener to improve ride comfort.

Pricing remains a mystery, but Lexus will offer a limited edition model dubbed the Inspiration Series.  Only 100 units will be available and they will each have a Structural Blue exterior with a blue top, gray accents and 21-inch wheels.  Additional information will be announced in the future as will details about a one-off LC 500 Convertible that will be auctioned off by Barrett-Jackson on January 17th.
