The self-effacing Volkswagen Polo wasn’t renowned for its potency until the firm’s engineers attached a supercharger to the 1272cc engine under the bonnet of the 1.3 GT model.
The result was a brawny GTI basher called the Polo G40, the suffix referring to the supercharger, the twin spiral chambers of which resembled the letter ‘G’ and were 40mm in width.
When Autocar tested the G40 Mk2, we described the effect of adding a supercharger as “nothing less than dramatic”. Peak power was raised to 113bhp at 6000rpm, with 111lb ft at 3600rpm. “These are outstanding figures for a 1300 and enable the Polo to step out of the junior GT class and into the tough GTI arena,” our tester wrote.
While the VW’s MacPherson strut front and semi-trailing arm rear suspension were largely unchanged, the G40’s spring and damper rates received attention and its fine-lattice alloys wore 175/60 Continental tyres. Other hot hatch accoutrements included some red piping and a semi-sporting steering wheel. Our testers described the overall effect as “neat and understated”.
There was nothing understated about the performance, however. “Its top speed of 119mph isn’t too far adrift of VW’s 122mph claim and is remarkable for a 1300cc engine,” reported our testers. “The 205 GTi’s 122mph just about fights off the challenge, but the Fiesta is left red-faced at 118mph.
“The G40 is embarrassingly accelerative, too. It sprints from rest to 60mph in 8.4sec, taking 0.5sec out of the XR2i and shaving 0.3sec off the 205’s time. This truly is big-capacity lugging power from a tiddler and it leaves its 1.6-litre rivals gasping.”
The story out on the road was mixed. The gearchange was described as “sticky and imprecise” and part-throttle response “wasn’t especially crisp”.
The chassis handled the power well, though: “Torque steer is mild and traction consistently good. The steering is accurate and communicative but afflicted by a curious over-centre action that pulls on to lock under power.”
Nevertheless, the G40 was described as “a lot of fun”, with mild understeer as the staple handling characteristic, garnished with “a generous dollop of (admittedly crude) throttle adjustability” that allowed a neutral balance to be achieved mid-corner.
“Grip was good rather than exceptional and the mediocre ride is better at high speeds than in town, but all in all the chassis feels impressively well sorted. It would be nice to say the same about the brakes but, alas, they suffer from dead initial travel and feel disconcertingly spongy.”
