Lexus GS430 Sport

With a powerful 4.3-litre V8 and rear-wheel drive, the GS430 has always been underrated, but in Sport trim it finally gets the muscular look many buyers want. The superb engine and smooth gearbox deliver their performance to greater effect with the firmer suspension, yet some fans will miss the standard car's smooth ride.

Becoming a rap star isn't easy, but if you haven't got the lyrical talents or the inflated ego, you can at least have the car to go with the lifestyle. With lowered suspension, big wheels and some far from subtle styling add-ons, the new Lexus GS430 Sport wouldn't look out of place on the drive of a California mansion. But how does it fit into the UK range?

Both the six-cylinder 3.0-litre GS300 and mighty 4.3-litre GS430 are now available in Sport trim, which not only adds some cosmetic muscle, but also tightens up the suspension to give more taut handling. Owners of standard models will instantly notice the suspension alterations, with the ride quality compromised by the stiffened springs, making uneven road surfaces a bind.

But the benefits are immediately felt when fast progress is needed. The 279bhp GS430 has always been quick in a straight line, but couple the 6.3-second 0-62mph time with this model's superb handling and you have a truly capable sports saloon.

As well as 18-inch alloys, the Sport gets an aggressive front air dam, new mesh grille and an unmissable rear spoiler. Inside, nearly every conceivable extra is standard, with sat-nav being the only obvious item left on the options list.

At £39,995, the new GS flagship is £2,300 more than the GS430 SE. Is it worth the extra? The styling is a matter of taste, but as a BMW and Mercedes-rivalling high-performance saloon, the Sport may soon be climbing the charts.
