What is it?
The third member of the Renault Laguna family – and the best-looking version by a mile. Renault only aims to sell about 2000 Laguna Coupes a year in the UK, but it hopes that this sophisticated-looking fastback will add some much-needed drama to the whole range.
GT spec brings leather upholstery and Renault’s rear-steer system, which boosts both low-speed manoeverability and high-speed stability.
The Coupe is about 7cm shorter in the wheelbase, and has a 3cm wider track than other Lagunas. UK buyers will be able to pick a 2.0-litre turbocharged petrol, a 2.0-litre turbodiesel and a 3.5-litre petrol V6.
However, we opted to test the range-topping powerplant, an all-new 3.0-litre turbodiesel V6 with 235bhp which will be shared with forthcoming Infiniti models.
This drives through a standard six-speed automatic gearbox, and produces an impressive 332lb ft of torque at just 1500 rpm.
What's it like?
The Laguna Coupe’s cabin is stylish and deeply impressive, continuing the good work begun in the existing Lagana hatch and estate.
The fascia has tasteful aluminium facings, plus superbly designed switchgear which is the match of any premium rival in terms of both look and feel.
All Coupe models get sportier seats and extra under-thigh support at their edge. The interior can carry four adults at a rather snug pinch, and the overall effect is luxurious and airy.
On the road, the Coupe keeps the refinement of the Laguna hatchback, offering excellent high-speed cruising. The engine is turning over at just 2700rpm at an indicated 100mph, and wind noise is very low.
The Coupe also gets firmer spring and damper settings, which can mean there’s a lumpiness in the ride at low speeds that takes getting used to.
Yet over suburban bumps it feels quiet and taut: Renault has found an extra 25 per cent of torsional stiffness in the two-door body, compared with the hatchback.
The engine’s strong output does a decent job of motivating the Laguna Coupe’s 1500kg body in a suitably sporty fashion.
The car feels powerful and long-legged, although its autobox can be a mite unresponsive when asked to provide a kickdown for overtaking. For quick downchanges the driver is better advised to intervene via the (pleasant-to-use) selector.
The diesel is barely recognisable as such above idle, only the 5000rpm redline on the tacho serves to give the game away, and in real-world driving it feels every bit as brisk as the petrol V6.
The four-wheel steer system works well, sharpening response in roundabouts, yet taming untidy high-speed lane-change manoeuvres.
Renault engineers say a tweak that started as a simple safety gadget has turned out to be an aid to driving pleasure, adding an 'on rails' feel in long, fast bends.
Should I buy one?
You should certainly give it serious consideration. This is a very good car: handsome, well-made, well-equipped and perfect for fast cruising. The low-speed ride isn’t the best in the business, but it’s a great high-speed mile-muncher.
