The two crossover models are priced from £21,749 for the Vitara and £20,749 for the S-Cross. The Swift Sport is priced from £21,570, although all three are being offered from launch with 0% PCP deals.
That is now the only powertrain option available on Suzuki's hatchback, with the brand seeking to meet upcoming emissions regulations. It uses a 48V set-up alongside a reworked version of the outgoing car's 1.4-litre turbocharged four-cylinder petrol engine.
The new powertrain generates 127bhp, down 11bhp on the outgoing model, although torque increases by 3lb ft to 173lb ft. The result is a quoted 0-62mph time that reduces by a second to 9.1sec, although the Swift Sport claims the same 130mph top speed as before.
The mild-hybrid system helps to generate a higher level of torque lower in the rev range, it is claimed. Efficiency increases are promised, and although the 50.1mpg quoted is little different to the outgoing car, that was measured under the older, less realistic NEDC economy test cycle.
The 48V system brings features such as an integrated starter-generator, which can power components in the car and operate as a starter motor to assist the petrol engine during initial acceleration. It can also idle the engine below 50mph using electric power from the motor.
The system puts out the same power and torque figures as the Swift Sport in the Vitara and S-Cross. The former promises a 0-62mph time of 9.5sec – the same as the non-hybrid – but WLTP-measured fuel economy rises from 43.1mpg to 49.7mpg. CO2 emissions also fall from 146g/km to 128g/km.
Oddly, the S-Cross hybrid's 9.5sec 0-62mph is 0.7sec quicker than the non-hybrid. It also improves WLTP fuel consumption from 40.6mpg to 50.1mpg and emits 127g/km of CO2 - a substantial 30g/km improvement.
A Suzuki spokesman told Autocar earlier this year: “It’s not about out-and-out power any more. We’re trying to make 48V work at a more efficient pace lower down the rev range.
“The Swift Sport has never been a hot hatch. The Swift Sport is a car to have fun in at good speeds, but safely and without getting into trouble.”
