It’s by

perfect combination of the nimbleness and lightness of a motorcycle with the security and safety of four wheels.

The eQooder has a range of around 90 miles and takes less than six hours to charge from a domestic socket.

It’s fitted with a reverse gear and even has regenerative braking to boost the battery.

IN 2016, Porsche stuck a fourcylinder turbo engine into its Boxster and Cayman models and added a 718 badge.

The number is a reference to a racing car the company built in the late 1950s and early 60s.

The engine is powerful, so no performance was lost moving from the old existing six-cylinder naturally aspirated ones. All jolly good so far.

Except that the new four-cylinder sounds like a Beetle if you’re being polite – or a farting pig if you’re not.

Although both the Boxster and Cayman 718s are better to drive and faster, sales dropped off because of the unappealing engine. The alternative, if you mourned the loss of the six-cylinder, was to buy a Cayman GT4.

This had a 4.0-litre engine borrowed from the 911 but without the turbochargers and with a litre of extra capacity. Porsche launched the second generation Cayman GT4 last year and we tested it in the summer.

At £75,000, it’s not cheap. But it’s the best sports car for any money.

Or it was until the car we’re testing today arrived, as the Cayman GTS is brilliant.

For starters, it uses the same engine as the GT4 – a

4.0-litre flat-six that’s naturally aspirated.

The only difference between the engines in the

GT4 and GTS is that in the former the motor revs to

8,000rpm and in the latter it hits 7,800rpm.

With those lost 200rpm goes 20bhp, but you won’t notice on the road because the GTS still has a mighty 394bhp and the same 431Nm of torque.

Porsche will have only done it for marketing reasons so the GT4 stays top dog and justifies the extra cost.

So, what do you lose having saved £11,000 by buying the £64,088 Cayman GTS? Again, not much that you will notice on public roads.

Firstly, it doesn’t have the same aero package as the GT4 – the rear wing has gone and there is no underbody diffuser. Bang goes 100kg of downforce at 150mph!

Also, the front suspension on the more extreme car has rose joints, whereas the GTS’ suspension has standard rubber bushes.

Rose joints are what you find on racing cars – they make the suspension geometry more accurate but tend to transmit more shocks from the road.

You’re going to love this car if you’re a traditionalist because, like the GT4, it
