2008 Lexus HPX!
The 2003 Lexus HPX Concept is all but a go for release sometime next year!
Having seen it in the flesh in 2003 at the New York International Auto Show, this is one incredible beast!
If it is to compete with the Infinit RX, it will have it beat by PLENTY in size and utility, as, from my eyes, it is similar, if not bigger than, the Caddy SRX, which was also at that show.
Suffice to say, the V8 implanted in it will be considerably stronger than the 320HP currently used in the Infiniti.
