Aston Martin Cygnet — spec data and generation history.
The Toyota iQ in a posh frock — Aston rebadged the Toyota city car with leather, hand-stitching and a wing badge to help meet European fleet CO2 averages. 1.3 four-cylinder (97 bhp), CVT or six-speed manual, FWD. Sold poorly (~150 in the UK out of a 4,000-projected total). AML built one V8 Vantage-engined Cygnet in 2018 (Q by Aston, 4.7 V8 — 430 bhp) as a one-off owner commission. The standard car is a curio; the V8 conversion is now a cult legend.
