It’s an unusual derivative line-up that sees Kia’s 1.4-litre turbocharged petrol engine powering both the cheapest and the most expensive Proceed in the range (the more powerful, lesser-equipped 1.6-litre Proceed GT is, rather surprisingly, cheaper at list price than our test car) – and it gives this powertrain a lot of notional ground to cover.
On refinement, the engine gets off to the right start. Agreeably quiet almost all of the time except at low revs and under load (when an intermittent, just-audible, under-bonnet rattle-cum-flutter made its curious presence known in our test car), it has creditable throttle response and makes a usefully stout amount of torque through the lower and middle thirds of the rev range. At high revs, however, the engine becomes a bit wheezy, apparently failing to make any more power once the crankshaft has spun beyond about 4500rpm, and therefore undermining the otherwise subtle but effectively conjured sense of dynamism the chassis produces.
And so when you compare the car’s performance level against the clock with that of mid-range petrol rivals, it’s a bit underwhelming. The Proceed was the better part of a second slower than the VW Golf 1.5 TSI Evo we tested in 2017, both from rest to 60mph and from 30-70mph through the gears.
