Last month we
tested Peugeot’s very first diesel-electric Hybrid the 3008 Hybrid4 and were
impressed by the technology on offer if not so much by the execution itself.
However Peugeot are ploughing on and earlier this year launched its second
hybrid, the new 508-based RXH.
Essentially the RXH
is a 508 SW with raised suspension, beefy body moldings and underbody
protection, larger wheels and the same Hybrid4 system we have seen previously.
Peugeot’s sole aim is to offer buyers a large, quality, family estate capable
of modest off-roading, good on-road manners with low running costs unseen
before.
The RXH commands a
healthy premium over the standard 2-wheel-drive 508 SW putting it in the same
arena as Audi’s desirable A4 Quattro Allroad and Volkswagens newly launched
Passat Alltrack. We find out whether the big cat has what it takes to rival the
best Germany has to offer.
What
is it?
Launched
in May 2012 the 508 RXH is Peugeot's foray into the increasingly popular rugged
four-wheel drive estate category. Its unique selling point is its hybrid-diesel
powerplant. The RXH's biggest attraction has to be its claimed combined fuel
economy in the late 60s (mpg) and meager emissions at just 107g/km. Under the
skin is the familiar 508 platform with multilink rear suspension with the 37bhp
electric motor mounted to it. The drivetrain is identical to that found on the
3008 Hybrid4 that we tested earlier this year. The RXH sits at the top of the
508 range with just one single, well equipped trim level which costs £33,695.
Standard equipment includes luxuries such as automatic lights and wipers,
cruise control, front and rear parking aids, 18” alloy wheels, panoramic roof,
Bizone climate control and colour head up display. Here we are testing a fully
loaded example with the addition of metallic paint, Open/Go keyless entry, full
leather interior with massage function driver’s seat and Xenon directional
lights with Led daytime running lights. Our car with extras comes in at
£36,770.

Anyone that has seen a
508 SW on the road will appreciate its superb looks. With its bold creases,
prominent waistline and generous dimensions it’s one of the classier cars in
its class. The RXH builds on this with the addition of a new “floating” grill
at the front and all new bumper with “cat-claw” LED daytime running lights. The
cars ride height has been raised by 50mm for improved ground clearance and benefits
from widened front and rear tracks nicely concealed by the very attractive,
rugged looking plastic arch and sill extensions with chrome highlights. There is
also range of new colours available exclusively to the RXH along with gorgeous
18” Attila alloy wheels. Arguable the RXH is the best looking 508 in the range;
its transition from sleek estate to rugged quasi-SUV seems to have been hugely
successful.
Inside is pure 508
which is not a bad starting point. Everything is sumptuously trimmed in thick,
quality materials with all of the switches operating with a lovely damped
action. The design itself is classy and sophisticated with a pleasing blend of
black plastics with chrome accents. Differentiating the RXH from its 508 siblings
is an eye-catching strip of trim that intersects the dashboard fading from
black to red and back to black again also carried over to the sides of the
lower centre console. Our car also had high quality leather seats with
mud-coloured brown stitching.
Carrying
five adults in comfort is easy in the RXH with ample head and legroom in the
front and back. The seats themselves couldn’t be more comfortable with plenty
of adjustment for the driver including extendable leg supports for those in the
front. A rake and reach adjustable steering column makes finding the perfect
driving position is easy. Unobtrusive a-pillars make for good forward
visibility helped further by the elevated view out thanks to the raised
suspension.
We
found the Head Up Display to be a really useful gadget rising from the top of
the dashboard in the drivers line of sight projecting the cars speed onto the
slim piece of glass – helpfully the digits turn green when in all-electric
mode. The navigation and cruise control information can also be projected onto
the display in crisp colour.
Despite
having a raised boot floor to house the rear electric motor and batteries
luggage capacity is still decent at 423 litres -90 litres down over the
standard SW-extending to 1439 litres with the seat folded down. This is likely
to be plenty big enough for the majority of buyers.
At
the heart of the RXH is Peugeot’s superb 1997cc 16v 163bhp common rail diesel
engine mated to a robotized 6 speed manual transmission. At the rear is a 37bhp electric motor with up to 200Nm of torque powering the rear wheels. What
makes this setup unique is that both power sources aren’t mechanically linked
in any way. Also there is no need to plug the HYbrid4 in to charge its Nickel
Metal Hydride batteries. Additionally an energy recovery system turns the
electric motor into a generator during deceleration increasing the cars range.
There
are a series of driving modes to choose from via the control selector mounted
on the centre console. Most drivers will leave the car in Auto which cleverly
juggles between power sources for optimised fuel economy. ZEV (Zero Emission
Vehicle) mode is perfect for around town running on electric power alone for
around two miles with the batteries fully charged. There is also a Sport mode
where diesel and electric come together producing 200bhp coupled with
quicker gear changes for what Peugeot calls "Dynamic Performance".
Finally there is a 4WD mode for some mild off-roading.
The
RXH drives very much like the conventional 508 SW. Admittedly when turning the
ignition key the car generates no noise at all as the diesel engine sits in
standby mode. Move the gear selector from N to A and gently push the
accelerator and the car begins to silently move forward with nothing more than
a whir. It’s an eerie sensation but one that’s novelty never wears off, just
watch out for pedestrians who may not be aware of your approach!
Once
40 mph is reached the diesel engine seamlessly takes over providing the needed
thrust for higher speeds. Stepping off the accelerator causes the % power
needle fall to “charge” helpfully charging the batteries ready for the next
urban encounter. At first the increased rate of deceleration takes some getting
used to but drivers can feel smug that this usually wasted kinetic energy is
being put to good use. The RXH also slips back into zero emissions mode when
slowing down.
As we have found with the 3008 hybrid we recently tested the flaws in
the gearbox still remain although to a lesser degree. In Auto mode far too
often it’s found searching for the correct gear sending engine revs and noise
levels soaring but gear changes are fairly smooth. There is also far too much
hesitation when pulling away from junctions forcing the driver to wait for
large gaps in the traffic before making a move.
Thankfully there is a way of getting the most out of the engine and
making smooth progress. We found Sport mode improved throttle response and made
gear changes quicker especially when swapping cogs manually using the steering
wheel paddles. In this mode you can take full advantage of the RXH’s linear
power delivery and 500nM of torque combined picking up speed with real
conviction. This is reflected in the sprint to 60mph taking just 8.8 seconds –
up from 9.5 seconds in Auto mode. In Sport mode however economy does suffer and
the RXH is not able to run in full electric mode.
Out on the road the RXH has lost some of the 508’s sparkle in terms of
ride and handling. The 508 already has a firm ride but it seems that the new
cars suspension has been stiffened further to counteract the additional
suspension travel resulted in a ride that always feels busy picking up even the
smallest imperfections and jolts over sharp ridges in the road. Despite a
firmer setup the loftier suspension also tends to wallow when dealing with
larger bumps. Thankfully on smoother A-roads and motorways everything settles
down providing a more supple, forgiving ride.
When tackling corners the RXH’s steering is nicely weighted and
provides just enough feedback for keener drivers. Levels of body roll have
increased but not by much and the brakes are powerful and fade free making for
a decent drive. There is also more than enough grip from the Michelin Pilot
Sport3 tyres. Refinement seems to have suffered at the arm of those grippy
tyres and bluff body moldings with far too much noise filtering into the cabin
making rougher surfaces more tiring than they should be.
We managed to get a deeply impressive 60 mpg from the RXH- not far off
the claimed 68mpg combined- whilst with us resulting in a range of over 800
miles despite spending the majority of its time on country roads. With
emissions of just 107g/km the RXH is noticeably cheaper than its rivals to tax
and will be a seriously attractive proposition for business users thanks to its
12% BIK taxation. Compared to the standard 2.0 HDi diesel 508 SW combined fuel
economy is likely to be around 19mpg less at 49mpg combined. Furthermore the
508 SW falls into four tax bands higher than the RXH in Band F meaning an extra
£115 outlay each year.

The Verdict 3.5/5
Whilst with us we found the RXH to be a well-rounded package and
excellent ownership proposition. We really liked its rugged looks and luxuriously
designed interior that can easily accommodate a family of five and their
luggage. We also found the fuel economy to be very good overall and the superb
driving experience of the standard 508 is still there if slightly diluted. We
found it hard to get on with the rougher ride quality that felt far too wallowy
and the relative lack of refinement. Then there is the robotised gearbox which
still has some way to go compared to those offered by rivals. In Auto mode its
changes are ponderous and it’s often confused, in manual Sport mode however the
RXH is much more rewarding to drive but economy suffers. Overall the RXH has a
lot to offer family and business buyers alike but is only for those who are
happy to spend the princely sum of nearly £34,000 on a Peugeot rather than an
ultimately more desirable, prestige brand such as Audi. It is likely to come
down to running costs which rivals will find hard to match.
