Laguna Coupe

Its achievement approaches our beloved
Peugeot 406 Coupe...

The
time was September 2007. The place was Frankfurt motor show. All the
limelight went to the stage of Renault, where a stunningly beautiful
coupe was displayed. It was called a concept, and its name suggested it
was based on Laguna. Somehow, Renault this time did not repeat the
faults in the weird-looking Laguna. It successfully shaped a beautiful
coupe with artistic lines, smooth flowing surfaces and a pure profile.
It stole the show where Jaguar XF, new Audi A4 and Aston Martin DBS
made world debut !
Exactly one year later, the production version of Renault Laguna Coupe
is introduced. Some may be disappointed that it loses a little sporty
flavours of the concept in the name of practicality. For example, the
low roof line of the concept has been raised by 26 mm to make life
easier for rear passengers. A thin intake has been opened at the
leading edge of the bonnet to help engine cooling, which damages the
sleek appearance slightly. The 18-inch wheels are also less well filled
the wheelarches than the 20-inch items found in the concept.
Nevertheless, these changes could not stop the Laguna Coupe from
winning our hearts. Its very graphical front end design and its
sculpted rear end are original. It is one of the few designs ever made
that really combines beauty, elegance and originality. Compare with it,
a BMW 3-Series Coupe looks strange, an Audi A5 looks unimaginative and
a Peugeot 407 Coupe looks unpolished. Its achievement approaches our
beloved Peugeot 406 Coupe.

Compare
with the regular Laguna 5-door hatchback, the 2-door Coupe has a
sportier profile, of course. It is 60 mm shorter overall and 65 shorter
in wheelbase. The width has been increased by 20 mm, the tracks have
been widened by 30 mm while the roof is lowered by 47 mm. On scale you
will find it undercuts an equivalent Laguna hatch by about 40
kilograms. On bending machine you will find its 2-door monocoque
chassis returns 25 percent higher torsional rigidity. All these figures
point to better driving dynamics. The only area it goes backward is
aerodynamics, as drag coefficient is increased from 0.293 to 0.307.
Despite of the shorter wheelbase and lower roofline, the cabin of
Laguna Coupe is still roomy by the standard of its kind. Four
six-footers will find pretty comfortable in it, which means its rear
seats far more usable than Audi A5. No one can quite match the Audi for
interior build quality, but this Renault can stand beside it without
feeling disgraceful. Its soft-plastic dashboard is basically the same
as the regular Laguna, which we described as "stylish, inviting and
high quality". Now with some aluminum inserts on the dash, transmission
tunnel and door panels, it looks even more delicious, delivering a
luxury ambience. In addition to the sporty bucket seats, you will
definitely prefer this interior than that of BMW.

As
expected, in order to compete with its more premium German rivals, the
Renault coupe is set around 15 percent cheaper yet offers more standard
equipments and practicality. It has a very good sound system, dual-zone
climate control, Bluetooth handsfree, keyless entry, parking sensor,
cruise control, xenon lights and leather seats. Another merit is a
spacious (423 liters) boot, which can be expanded further by folding
the rear seat flat. This can be done by pulling a handle in the boot, a
convenient feature carried over from the Laguna estate. French cars are
rarely so thoughtful, let alone a coupe.
Laguna Coupe is the first Renault coupe since the Fuego of the early
1980s. Back in those days, the fastest Fuego 1.6 turbo could top only
118 mph and accelerate from rest to 60 mph in 9.3 seconds. The world
changed a lot during these 25 years. Even though Laguna Coupe is not
exactly fast by today's standards, it can reach 150 mph and 0-60 mph
takes 6.9 seconds, and this is diesel-powered ! Renault's new 3.0-liter
diesel V6 is state of the art. It has a compact graphite iron cylinder
block to reduce noise and weight. DOHC 24-valve cylinder heads,
variable geometry turbocharger and 1600-bar second generation
common-rail direct injection help output and fuel economy. This engine
has a potential of 265 horsepower and 406 lb-ft of torque, but to avoid
spinning the front wheels of Laguna Coupe it is detuned to 235 hp and
332 lb-ft. (Expect the rear-drive Infiniti could realize its
potential.) Mating with a compulsory 6-speed automatic transmission,
the combo delivers a smooth, refined and solid performance while
returning near 40 mpg fuel economy !

Another
top engine comes from Nissan - the 3.5-liter VQ35DE V6. Unfortunately,
it is detuned to 240 horsepower only for this application, far short of
the 290 hp level in the American-market Nissan Maxima. Performance is
more or less the same as the diesel V6, but the latter is definitely
superior for in-gear acceleration due to its strong mid-range torque.
The diesel engine is also quieter in cruising, because it barely
registers 2700 rpm at 100 mph. As a result, few people will choose the
Nissan V6. Instead, those could not afford a V6 may look to the 205 hp
2.0 turbo or 180 hp 2.0 turbo diesel, both are carried over from Laguna
GT. At the bottom of the range is a 150 hp version of the 2.0 turbo
diesel which does without 4-wheel steering.
Predictably, the Renault coupe does not intend to challenge BMW for
driving dynamics. Even if it does, its modest architecture would not
allow. You must bear in mind that Laguna is an unsophisticated family
car using front-wheel drive and simple MacPherson struts and
torsion-beam (semi-independent) suspensions. In my memory, no cars
using such configuration has ever been successful to offer BMW-level of
dynamics. However, Renault still did some works to narrow the gap. Most
notably is the adoption of a 4-wheel steering system, which was
originated from Nissan's Infiniti division and introduced to Laguna GT
recently. At low speed manoeuvre, the 4WS system steers the rear wheels
in opposite direction to shorten turning circle. As a result, the
driver feels the cornering response sharper, the rear wheels more tide
down to the road (as they are less prone to slide by centrifugal force)
and therefore less understeer and less untidy behaviour. In other
words, it feels like cornering "on rails". At higher speed, the rear
wheels steer in the same direction as the front wheels, so lane change
becomes fluent and more stable.

The least painful way to break away

This
is not just theory. On the road, the Laguna Coupe feels far sportier
than its nose-heavy configuration suggested. It feels quite agile,
grippy and stable through mountain roads. It still can't challenge BMW,
but it is comparable to Audi, if not as quick against the clock.
However, its strength is still high-speed cruising, where its diesel V6
works quietly, its suspensions ride smoothly (it rides worse on
low-speed small irregularities) and you can enjoy its superb interior
environment.
Overall, the Laguna Coupe is an impressive effort. It is beautiful,
well built, luxury and superb for motorway cruising. These merits are
offset by its slower performance and the lack of driving involvement.
However, considering its rarity and good value for money, it is
probably the least painful way to break away from your default BMW.
