Lexus GS (2012 – 2018) At A Glance

High quality and superbly built. Strong performance and relatively low CO2 from 450h. Impressively refined. GS F V8 fast but flawed.

Steering feels too remote. Still no diesel engine. Firm ride on F Sport models.

Insurance Groups are between 26–48
On average it achieves 80% of the official MPG figure

The Lexus GS has carved out a niche as an upmarket and somewhat leftfield alternative to large saloons like the BMW 5 Series and Mercedes-Benz E-Class. For those who value quality and refinement the Lexus ticks a lot of boxes. It's helped by Lexus dealers  - known as the best in the business and backed up by top marks in the various customer satisfaction surveys like JD Power. It's no surprise that the brand has one of the highest rates of repeat buyers.

This latest GS builds on the qualities of the old model but Lexus has worked to add a dash of style and driver enjoyment to the mix. In terms of looks it's a lot more angular at the front and it's a similar story at the back where the stretched lights make it appear wider. Overall it has a lot more road presence than before.

The improvements are most noticeable inside with a far better interior in terms of design and quality. There are less obvious Toyota elements and a far more stylish feel with features like the solid metal controls for the stereo and the analogue clock between the air vents. There's more space than before and it feels much more like a premium car than the previous GS did.

As before Lexus isn't fitting a diesel engine to the GS range - something which will mean many buyers immediately rule it out - instead it's sticking with standard petrols and a hybrid version. The GS450h is the impressive hybrid and it combines swift performance with low CO2 and good fuel economy considering its power.

There's also a GS250 powered by a 2.5-litre V6 petrol with more than 200bhp which is significantly cheaper than the hybrid model. Starting prices are fairly high, but all models come highly equipped as standard although entry-level versions don't get sat nav.

Driving the GS is relaxing and serene - it's an ideal long distance motorway car thanks to the impressive refinement - but it's not as good on demanding roads with artificial steering feel and wooden brakes.

Do I need an extended warranty for my Lexus 300h GS?
I have a Lexus 300h GS which runs out of warranty in June 2017. My local dealer is offering an extended warranty for £1095 for two years, including AA cover. Do you think it is a good idea to have this and is the price fair?
It's a standard sort of price but a Lexus 300h GS is one of the World's most reliable cars. I wouldn't bother, but it depends how much you value absolute peace of mind.

Where can I get a replacement key for my Lexus?
I have only one key for my Lexus GS 450H (62 plate). As it is a keyless entry car, I would like to get a second key. Do you know where I could get one from?
Try a branch of Timpsons in the High Street, side street or in a Shopping Mall. No joy there, links to keys and locksmiths in this directory: The first two on the list apparently give very good, very fast and very cheap service.

Buying an exec saloon for a short commute - A6 or GS?
I drive a 2005 Lexus GS300 and love the reliability, standard level of equipment and comfort. I want to change up to a newer car (1-3 years old). I cover 20,000 miles per year, 70 per cent of which is a short distance commute each day lasting no more than 20 miles. I'm thinking a Lexus GS300H 2014/15 OR Audi A6 2.0 diesel 2014/15. My gut tells me the Lexus is the better option for me based on my driving habits but would appreciate your thoughts or suggestions of an alternative not mentioned here.
Definitely the Lexus hybrid rather than the Audi diesel.

Need an executive car with a smooth ride
I have a Lexus GS300H at the moment on 17-inch wheels. I'd like to replace it with something that provides a smoother ride over rough roads. Would I be better off with something like a Lexus NX or anther make?
If you mean typical, British, potholed A, B and white roads, then nothing less than 55 profile tyres and preferably air suspension as on a Range Rover or the bigger Discovery. If you mean rocky tracks, then you'll need a minimum 60 profile tyres and the Hyunda Santa Fe and KIA Sorento this fitted are remarkably good on this sort of road. Whatever, it must have fully independent suspension. A solid axle at the back as on a pick-up truck is no good for ride comfort. NXs tend to come on big wheels with low profile tyres and don't have brilliant suspension.
