Speaking to TMR at the Melbourne Grand Prix, Palmer said the need for a car like the Cygnet - which was powered by a naturally-aspirated 1.3 litre inline four and consumed a very un-Aston-like 4.0 l/100km (but helped bring the company's "fleet emissions" into line with European legislation) - had diminished due to the rise of electric powertrains.
"Aston sits in the high-luxury segment, so you can put different cars in there," Dr Palmer said to TMR.
"I think there are better ways of meeting emissions regulations, like electric powertrains for example, so I don’t think we need to make a Cygnet - at least definitely not under the Aston Martin name."
Palmer confirmed that the next-generation Rapide four-door will become an all-electric Tesla fighter when it launches in 2018, and the production version of the DBX concept (above) is expected to make use of the same tech. With both consuming zero fuel, Aston's fleet emissions average tumbles.
But what of a high-output, low displacement option rather than a frugal city hatchback?
Aston Martin's engineering alliance with Daimler allows the small British marque access to AMG's catalogue of high-output turbo engines - the 4.0 litre twin-turbo V8 of the C63 will likely power the next Vantage - which presumably also includes the A45's hypo 280kW/475Nm 2.0 litre inline four (below).
However when asked whether Aston would consider using that engine in an entry-level model, Palmer responded in the negative:
"Is it theoretically possible? I guess the answer is yes. Is it going to happen? Probably not on my watch," he said.
