Most Efficient Convertibles

Below are the top 10 most efficient convertibles according to their highway fuel economy.

All are foreign, petrol fueled performance cars apart from our winner, the San Storm, which has a tiny 1.2 litre diesel engine.

It would be great to see more Indian manufacturers breaking into this car category to give consumers greater choice for an inexpensive efficient convertible.

San Motors Storm

The most efficient convertible is the San Motors Storm.

The Storm occupies a unique position, being the only budget convertible available in India. Costing just Rs 5,95,000 (the next most efficient convertible, the Porsche Boxster, costs over ten times this!), the Storm is the only cheap car to offer that fun wind in your hair experience.

Unlike the rest of the cars in this list though, the San Motors Storm is not a sports car. Its 1.2 litre Renault petrol engine, while economical, offers just 58.5bhp which takes the car from 0-100kph in a slow 14.6 seconds (the Boxster does it in 5.8 seconds!). Top speed is just 143kph.
