We say Undeniably pricey, but a refined, sizeable limo. But the LS still lags behind Jaguar, Mercedes and BMW all round.Performance Fast and torquey across the range. The 4.3-litre V8 is a real powerhouse; newer 5.0 petrol V8 hybrid outputs the best part of 400 horses and torques.Emissions Fuel consumption of 30mpg and CO2 under 220g/km is testament to Lexus’ hybrid technology.Driving Suspension and computer make sure the ride's always smooth, with loads of grip and responsive steering – it’s fast but the LS is designed for comfortable, sedentary driving above all.Feel Engine is near-silent and the LS cabin is well insulated. Superb motorway cruiser and a very good limousine in long-wheelbase format.Space Acres and swathes of room everywhere. To boot there's a huge, er, boot in the LS. A long-wheelbase model adds even more room inside.Equipment Everything is standard on the LS. Soft-closing doors and massaging seats are among the unusual options.Price The LS costs an absolute packet to buy and run, with prices starting at above £90K it’s aimed squarely at Mercedes S-Class and above markets. High specification, decent running costs but this is a fearsomely expensive car.Quality Lexus engines are reliable and the LS are supremely comfortable inside.Safety The LS has loads of airbags and plenty of electronic aids to prevent an accident in the first place.Pros Great engine, huge inside, loads of standard kit.Cons Massive running and buying costs. Looks like a slab of rock.Alternatives Mercedes S-Class, Jaguar XJ, Maserati Quattroporte
