When will the 2.4T HEV be available?

The 2.4T is a front-wheel drive engine. If you like it, you can go for the sporty version of the Crown. The SD is based on a rear-wheel drive platform. Beyond this, there's the 2.5, and moving up from there, you have the V6 and V8 options.

The 2.4T is gone.

Toyota currently does not have a 2.4T front-engine, rear-wheel-drive powertrain.

Just be patient, soon there will be a V12 Crown available for 100,000 RMB, with lifetime free fuel.
