Aston Martin is developing an all-new and ultra-exclusive supercar that bears the codename One-77. The British marque intends to build a mere 77 examples of the supercar that will be based on carbon fibre chassis with a handcrafted aluminium body. Power will come from a massive 7.0-liter V12 engine. The Aston Martin One-77 is expected to be launched in 2009 with a price tag that’s said to be in the £1 million range.
