Currently the cheapest GS on sale (the GS300) retails for $94,814, which is around $10,000 more expensive than the entry-level BMW 5-Series and Mercedes-Benz E-Class, and $11,000 more expensive then the entry-level Audi A6.
The new variant will allow Lexus Australia to offer more direct competition to its key German rivals, such as the BMW 520i and Mercedes-Benz E250 CGI.
The Lexus GS250 comes with a 2.5-litre V6 engine producing 154kW of power and is backed up by a six-speed automatic transmission with paddle shifters and throttle-blipping technology on downshifts. Acceleration from 0-100km/h takes 8.4 seconds.
Like the rest of the GS range, the GS250 will be available with the optional F Sport package which gives the GS a sporty character. Revisions include more aggressive styling with new front and rear bumpers, 19-inch alloy wheels, sports suspension, uprated brakes, and various F Sport badges and logos.
Pricing for the GS250 will be announced closer to its launch.
