First we have the Park Avenue. Coming in with the standard 3.6L V6. This will take care of the lower end Luxury market.
Then we have the Roadmaster. Standard with the DI 3.6L V6, then stepping up to V8 power in the form of the 6.0L V8 and then the Ultra V8 and V12. This would take care of the upper end of the market with a more sporting suspension. Think Audi S8
Both will also be available with Diesel of various sizes and the obligatory Hybrid drivetrains
