The MG Dynamo is about the same size as a Volkswagen Up, and weighs roughly the same as the electric version of that car, at 1080kg. Its 114lb ft of torque is available instantly, propelling the Dynamo from 0-31mph in 5.3 seconds. A BMW i3 will accelerate up to the same speed in around 3.5 seconds.

No further performance figures have been revealed, but assuming the Dynamo matches the figures for the Roewe E50, expect 0-62mph in 14.6 seconds and top speed of 81mph. It’s compatible with both AC and DC charging, which means a full charge takes six hours in a three-pin plug, or 80% can be replenished in 30 minutes using a rapid charger.

While the Dynamo is billed as a concept, the fact it is based on an existing electric car makes it much more feasible as a production model. One of the biggest considerations for MG will be the price UK buyers are asked to pay.

In China, the E50 starts at the equivalent of £28,000, but after local and national grants and exemptions, it costs more like £11,500. A UK price similar to the latter could make it a very interesting rival to the likes of the Renault Zoe and Volkswagen e-Up.

The MG Dynamo concept car is on display at the SMMT in Westminster until April 28.
