LEXUS is aiming to knock BMW off its junior executive perch with its first ever diesel model, which is an impressive oil-burning IS saloon.
The 2.2-litre model costs from £22,243. which makes the IS220d about £200 less expensive than the 2.5-litre petrol model.
There is only a small performance penalty and as the diesel model is significantly more economical and cheaper to run as a company car Lexus reckons that the rival BMW 3 Series diesel will suffer.
It is generously equipped with full climate control, a six-CD changer, cruise control, alloy wheels, remote central locking, keyless entry and engine start-up, electric windows and electrically folding and adjustable door mirrors.
Safety and security are also impressive, with front, side, curtain and knee airbags, stability and traction control and an alarm.
There is also an SE version costing £3,000 more, which adds 17-inch alloy wheels, leather upholstery and electrically adjustable front seats with memory settings.
One nice touch is that in addition to being heated the seats can also be cooled.
There are also Sport models with suede-effect upholstery, lowered suspension, even wider-diameter wheels and prices from £26,968.
The SE-L versions cost £900 more and gain wood trim, automatic wipers, front and rear parking sensors, an electrically adjustable steering column and an electrically operated sunblind for the back window.
The 2.2-litre diesel engine generates 175bhp for a 0-60mph acceleration time of 8.9 seconds, a top speed of 135mph, economy of 45mpg and a monthly tax bill of £125 or £227 depending upon the rate at which the user pays tax.
Whilst there is no denying that there are hugely impressive alternatives from BMW, Audi, Saab, Mercedes-Benz and several others, Lexus has a loyal following.
Its cars are stylish in an understated way, supremely well built, utterly reliable and boast just about the best residual values of all.
The IS diesel is no better than the BMW or Audi but it is just as good and it is something different, which is precisely what many discerning motorists increasingly want.
