New details have emerged about the upcoming 2014 Mazda MX-5 and Alfa Romeo Spider.

A diesel engine is being considered by Mazda for the new MX-5 but they worry it will add weight and also might make the car harder to sell since probably there won't be a large market for a diesel-powered roadster. In addition, Mazda prefers the high-revving capabilities of a gasoline mill.

Speaking of a gasoline engine, the 2014 Mazda MX-5 is tipped to receive a naturally-aspirated 1.6-liter SkyActiv engine producing approximately 130 bhp (97 kW). Its sister, the Alfa Romeo Spider, is likely to feature a 1.4-liter "TB" turbocharged engine rated at around 120 bhp (89 kW). Alfa could also offer a more powerful MultiAir engine with up to 296 bhp (221 kW).

Both cars will probably be offered as standard with a 6-speed manual gearbox, while for more money clients will be able to opt for a 6-speed automatic with steering wheel-mounted paddle shifters.

In terms of size and weight, Mazda wants the new MX-5 to have just about the same dimensions as the original model, with a curb weight of just 800 kg (1,763 lbs).
