Aston Martin May Use Toyota Engines

Aston Martin May Use Toyota Engines

Last week, an Autocar report indicated that Aston Martin had some interest in smaller three-, four- and six-cylinder engines. The report sounded as though Aston was developing the engines in house, but a more obvious solution would be to look at existing small engines from other manufacturers. A new report points to Toyota as a possible source. 

Aston already borrowed an engine (and entire car) from Toyota in building the decorated Toyota iQ called the Cygnet, so it makes some sense that it would go right back to Toyota for its next eco move. Amsterdam newspaper Der Telegraaf reports that Aston is looking at several possibilities.

On the plus side, the focus of the report isn't on Corolla four-cylinders, but Lexus V-8 and, even, V-10 options. Those engines may not seem small, but given the V-12 and V-8 stock that Aston is working with now, they could deliver some emissions benefits.

Frankly, we're a little skeptical of the report. Besides the fact that we've never read a line of Der Telegraaf until today and don't know its reputation as an auto news source, it seems strange that Aston would be pursuing big V-8 and V-10 engines, especially in light of the report on three- and four-cylinder engines. The Cygnet has proven that Aston Martin is serious about meeting emissions regulations and isn't afraid to take drastic measures to do so, so why fiddle around with slight gains from Toyota-sourced V-8 and V-10 models? If anything, we'd think it'd be looking at Toyota's V-6 and four-cylinder stock.

Perhaps Aston is thinking of using Toyota's engines as sort of compromise between emissions cuts and performance, either in its existing or future sports cars. Still, when equipped to the Lexus LFA, the 4.8-liter V-10 delivers a measly 11/16 mpg and coughs out 741 g of CO2 per mile - worse than anything in Aston's standard fleet, even the V-12-powered DBS flagship. So why would Aston be looking at it in relation to cutting emissions? A V-8 could be a fitting compromise, but the report is a little too shallow to take at face value. We'll wait until more information surfaces before believing it.
