It won't just be sitting on a turntable in the Lexus marquee either - showgoers will be able to take the new IS for a spin up Goodwood's famous driveway.
However, with the petrol-electric IS 300h being an entirely new addition to the IS range - which is one of the last Lexus model lines to get a hybrid powertrain option - it's safe to say that the IS 300h is the one that the public and press will be most curious about.
The IS 300h is also the first IS to make use of a four-cylinder petrol engine (we're not counting the Japanese market Toyota Altezza, which used the first-generation IS chassis), and produces a total of 162kW with the aid of an electric motor.
Fuel consumption for the IS 300h is claimed to be just 4.3 l/100km, which would make the IS 300h one of the most environmentally friendly options in the luxury segment - besides Lexus' own CT 200h, of course.
But it's not all about economy. Lexus says the new IS is built around a more rigid chassis, with drive continuing to go to the rear wheels.
F Sport models also get adaptive suspension, and Lexus has tuned the new IS with a focus on handling.
The Goodwood Festival of Speed opens on 12 July.
