The Chief Engineer & Chief Designer of the Lexus LC 500 Convertible chat about how they achieved the perfect balance of function and beauty.
What does it take to make the world’s most beautiful convertible? For the team behind the new Lexus LC 500 Convertible, achieving that dream called for much more than simply swapping the LC Coupe’s fixed roof with a soft-top. There are strong family ties between the two amazing Lexus LC models, but it’s the details under the skin that count the most, according to Chief Designer Tadao Mori and Chief Engineer Yasushi Muto, as they take us through the Lexus LC 500 Convertible design process.
“Our biggest challenge was always how we would keep the trunk line low, while still allowing room for load space and stowing the roof. With other carmakers, you’ll often see a high rear line, but we wanted to make this the most beautiful convertible, keeping the best lines whether the roof is up or down. We’re really proud of how we have kept the top of the rear wings so low, keeping the feeling of a low centre of gravity.”, shared Chief Designer Tadao Mori.
Achieving this was no simple task. It meant the roof had to be folded into what seemed an impossibly small space behind the rear seats. According to Chief Engineer Yasushi Muto to make this possible, every bend in the roof had to be a different size, so they had to engineer a complex and unique mechanism. It’s the first soft-top that Lexus has made, and the team worked in close collaboration with specialist supplier Magna in Austria to achieve the perfect results.
In addition to the smart, compact roof design, Lexus’ famed quality is also evident in the way the LC 500 Convertible’s roof opens and closes.
“When you operate the roof, one will notice that there’s a pause at the beginning and end of the sequence, with faster movement in between. This is intentional, it’s a way of communicating elegance in moving parts that has been part of the Lexus DNA right from the start with the first-generation LS sedan.”, says Muto.
There is no value in a car that looks great but is impossible to live with, so beauty has to be balanced with practicality.
“The balance itself isn’t difficult to understand – we call it functional beauty – but achieving it was very difficult. For example, we had to add bracing to keep the body rigid but also needed to keep space to stow the roof. So we developed a new rear suspension brace made of aluminium that gives good rigidity but is also compact. Its design also helped us keep the car’s beautiful silhouette.”, Muto adds.
Both Mori and Muto love top-down driving. Mori drove a classic MG sports car for more than a decade and they are enthused about the special sense of freedom it gives and a connection with the natural world around you.
On his favourite aspect of the new car, Muto shared, “When I’m on a winding road and I press the accelerator or the brake so the car downshifts, I love the sound of the engine, it’s direct and exciting and unique to a naturally aspirated V8. I also love the view from the rear of the car. You can see just how the interior design merges with the exterior to make a very beautiful thing.”
For Mori, the joy is in the details, he says, “For example, the button to open and close the roof is hidden in a palm rest like a little gem. It’s not on show, it’s a special control that nobody else can see. The seats, too, are sports-level quality, covered in leather with a special perforation that’s not just functional, but also creates a beautiful pattern and high-quality feel.”
The LC 500 Convertible boasts a naturally-aspirated 5.0-litre V8 engine producing 351kW and 540 Nm of torque at 4800 rpm. Connected to the DirectShift-10 automatic transmission, this engine gives the LC linear, yet invigorating acceleration. Power output will be tuned according to driving style, with smooth acceleration character during normal commuting and aggression at the limit when the driver desires.
