Lexus Rx450H+ vs Peugeot 308

What's the difference?

The new Lexus RX450h+ Sports Luxury is packed with a wealth of premium features and strikes a solid balance between refinement and practicality. There are enough thoughtful touches that make everyday driving a little easier.

You’ll get the most out of the plug-in hybrid powertrain if you’re able to charge it regularly; ideally every day. That might not always be practical for busy people on the go, but overall, the RX450h+ manages to blend efficiency with Lexus’ signature comfort and quality.

The 308 GT Sport plug-in hybrid is a beautifully designed small hatch that is comfortable, enjoyable and easy to drive. The electric motor gives this hatch good acceleration and the equally impressive handling makes for a fun car to drive too. There's good storage, a decent boot and room for even tall people like me in those back seats.

There are two clear drawbacks, however: the price is steep compared to the petrol version; and you'll need to plug the vehicle into a power supply each night if you drive the car daily and want to achieve the 2.4L/100km fuel economy we did in this test.

Last, but probably the most important thing you'll read is that Peugeot will bring fully electric cars to Australia from the second half of 2023, from SUVs to (hopefully) the battery electric version of this very 308 hatch.

If it was my money, I'd hold on - you're going to have your next car for quite a long time so it's worth waiting for the fully electric versions.

The RX isn’t breaking new ground with its plug-in hybrid design, but it still delivers that signature Lexus understated refinement.

The strong, flowing body lines, 21-inch alloy wheels and updated 'spindle grille' all give it presence without screaming for attention.

And in a segment where boxy and bulky designs tend to dominate, the RX’s swoopy silhouette helps it stand apart in all the right ways.

Inside, the cabin feels considered and luxurious. There's a heavy use of premium materials, including the leather and suede upholstery, plush soft-touch surfaces and the big, crisp displays that make the space feel modern and high-end.

The panoramic sunroof brings in loads of natural light, too, which is especially welcome given the dark headliner that might otherwise feel a little heavy.

If I have one gripe, it’s the thin steering wheel, which doesn’t quite match the otherwise solid, tactile feel of the rest of the interior. But overall, the cabin is a space that feels luxurious and well-executed. It's quietly confident, just like the RX.

There hasn't been a Peugeot in the last five years that wasn't stunning. There's the high quality feel in their build, and premium yet unique look - like a new Volvo but with more flair. And the 308 hatch and this hybrid version has all of that.

From the sinister looking LED tail-lights to the wide mesh grille, you really get the feeling that Peugeot is hitting its design stride.

This 308 GT Sport plug-in hybrid looks identical to the petrol version with its low, wide stance, and big dark alloy wheels that fill up its arches.

The cabin is sporty, lavish and minimalist with quilted leather upholstery seats, the digital driver display and media screen, and avant garde small angular steering wheel.

The RX cabin is thoughtfully laid out and impressively practical, with a premium feel that doesn’t come at the cost of everyday usability.

Up front, there’s plenty of space for driver and passenger, yet the stepped dash design brings a sense of intimacy. The electric front seats are seriously comfortable, with four-way lumbar support and extra adjustment functions that make this an easy choice for long drives.

Storage options are generous, too. There’s a clever dual-opening centre console, large glove box, multiple phone-sized shelves, map pockets and a couple of cup- and drink holders in each row.

Charging is taken care of by four USB-C ports, one USB-A port and a wireless charging pad.

Tech is up-to-date and well-integrated. The upgraded 14-inch media display looks crisp, supports wireless Apple CarPlay and Android Auto, and is paired with a revamped 12.3-inch digital instrument cluster and a colour head-up display.

The cluster’s new layout is modern and much easier to read than the previous offering. The digital rear view mirror also earns its keep when the cabin’s packed with passengers or gear.

One of my favourite touches? The seat controls on the side of the front passenger seat. It makes quick work of moving the seat forward, especially helpful when you’ve got a kid clambering in with a school bag full of projects.

Access to the rear row is easy, but the stadium-style seating, where you're perched noticeably higher than those in the front, won’t be for everyone.

That said, the rear seats are plush and padded, though they lack side bolsters, which rear passengers might notice during cornering.

Legroom is generous and the hardened kickplates are a dream to clean when your child’s treating the seatbacks like a climbing wall.

My eight-year old gives the back seat a glowing review, thanks to its creature comforts, including rear climate control, directional air vents, seat heating/ventilation on the outboard seats, two USB-C ports and retractable sun-blinds, which are a crowd favourite in our household.

There are three top-tether anchor points, and the bench is wide enough to fit three child seats, though bulky booster seats might be tricky due to the raised seating height.

At the back, the boot is well set up for families, offering electrically folding rear seats, a 12-volt socket, flat loading floor, and a hands-free powered tailgate.

Under the floor, there’s a small compartment for your charging cables (Lexus throws in two!) and a usable 612L of capacity when all seats are in use. One downside, though, is the lack of a spare tyre as you just get a tyre repair/inflation kit.

Peugeot's 308 is a small hatch, think Toyota Corolla, only beautiful and more spacious.

So, the 308 can carry five people with just enough head and legroom for a semi-giant like me (I'm 191cm) to sit behind his driving position.

There's good cabin storage with large door pockets, a long and deep storage box under the centre armrest up front along with two cupholders up there, too.

The boot has a cargo capacity of 361 litres, which isn't bad for this class.

To power devices there's a wireless phone charger under the dash, and USB ports for front and rear passengers.

A quirky Peugeot design feature is the low-placed angular steering wheel. I found had to squeeze my knees past to sit in the driver's seat. I'm not sure what size human was used as the test case for this but it wasn't somebody with stilts like mine, I can tell you that.

The 308 GT Sport plug-in hybrid lists for $64,990 before on-road costs. The ‘GT Sport' part of the name is the grade and the hybrid only comes in this grade. In comparison the priciest petrol 308 hatch is the GT Premium for $48,990. The 308 GT Premium also comes in wagon form and that's $50,490. Alas the wagon doesn't come as a hybrid.

Is it good value? Nope. A charge of $16,000 over the cost of the GT Premium petrol version with almost identical standard features is pretty unreasonable. It's also not good value when you could buy a fully electric car about the same size such as a new Tesla Model 3 for $64,300, or a Polestar 2 for even less at $63,900.

However if your heart is set on a PHEV, the main competitor is another Euro hatch - the Cupra Leon VZe from $59,990.

The 308 GT Sport plug-in hybrid standard features include LED matrix headlights, 18-inch alloy wheels and a panoramic sunroof, while inside there are two 10-inch displays - one for the media system and one for the driver's gauges.

It also has black full-grain Nappa leather seats (heated and massaging for the driver and front passenger), a 10-speaker Focal stereo system, proximity unlocking, dual-zone climate control, sat nav, wireless phone charging, plus Apple CarPlay and Android Auto.

Under the bonnet the RX450h+ Sports Luxury runs a plug-in hybrid powertrain that pairs a 2.5-litre four-cylinder petrol engine with a CVT auto and dual electric motors - one on each axle. Together, they produce a total of 227kW of power, though Lexus doesn’t quote a combined torque figure.

Still, it’s quick off the mark for a large SUV, with a 0-100km/h time of 6.5 seconds. There’s more than enough grunt for daily driving and overtaking, even if it doesn’t quite match the outright power of its key PHEV rivals.

The 308 GT Sport plug-in hybrid has a 1.6-litre turbo-petrol engine making 132kW and 250Nm combined with an electric motor at the front wheels making 81kW and 320Nm.

The combined output of the engine and motor working together is 165kW and 360Nm, and sending that grunt to the front wheels only is an eight-speed automatic transmission.

Acceleration is good. We're talking 0-100km/h in 7.4 seconds which is more than two seconds quicker than the petrol-only variant.

The plug-in hybrid system brings solid efficiency, with claimed fuel use of just 1.3L/100km. In real-world conditions (mostly urban driving with regular recharging) I managed a respectable 4.8L/100km, which makes a strong case for the hybrid set-up.

The fuel tank holds 55 litres and it's worth noting Lexus recommends using a minimum of 95 RON unleaded petrol to fill it.

Using our real-world economy figure you can expect a range in excess of 1100km between fills.

The RX450h+ is fitted with a relatively small 18.1kWh lithium-ion battery, supporting an NEDC electric-only range of up to 65km.

While that’s fine for short daily trips, it’s shorter than you'd ideally want in a family SUV of this size and it lags behind rivals like the BMW X5 and Volvo XC90 in this department.

Charging is simple enough. The RX uses a Type 2 charging port and accepts up to 7.0kW on AC power, which means a full charge takes around 7.5 hours, perfect for overnight top-ups. Lexus also includes an at-home charging cable and second adapter cable as standard, which is a thoughtful touch.

This is what it's all about right? Well, Peugeot says that after a combination of open and urban roads the 308 GT Sport plug-in hybrid will use 1.3L/100km.

At the launch I did a 34km test loop through Sydney's Northern Beaches with a good mix of morning traffic and hilly terrain. At the end of my journey the trip computer reported an average fuel consumption of 2.4L/100km.

I drove the entire loop in Hybrid mode, but there is a Sport mode, a Battery Save mode and EV mode.

If you were to drive in EV mode Peugeot says the electric driving range with a full battery is 60km.

At the start of my drive the battery was about three-quarters charged with the gauges displaying 38km of range.

A mileage of 2.4L/100km is still excellent fuel economy and from experience I can tell you a petrol-only variant would be up around the 8.0 or 9.0L/100km mark for the same trip.

There is a catch, and that is you'll need to plug in your hybrid 308 daily to charge the battery if you plan to achieve the fuel economy I did.

Charging will be slow, however, because Peugeot has fitted this hybrid with a small 3.7kW on-board charger. So, even using a fast charger you'll be looking at more than four hours to fully charge the 12.4kWh lithium-ion battery.

This charging time and small electric driving range in return could be a deal breaker for some and it's the reason why I've given the 308 GT Sport plug-in hybrid a lower mark. If you aren't always charging this car your fuel usage will rocket. New buyers unaware of this could end up using more petrol than ever.

A fully electric vehicle may be a better solution for city dwellers.

The RX450h+ delivers power that’s pert and prompt, with genuine bursts of acceleration that make driving fun. It’s always ready to go and there's no lag in stop-start traffic - which gives it a lively, dynamic feel around town.

The transition between petrol and electric power is seamless; you hardly notice the switch, which makes for a smooth, refined driving experience. The cabin is impressively quiet, even on the highway, making long trips comfortable and peaceful.

Regenerative braking isn’t adjustable and is subtle enough that many won’t notice it which is likely a plus for fans of traditional internal combustion engines who are making the PHEV leap.

The adaptive variable suspension adds a sporty edge to handling, letting you confidently take corners at speed. There’s some body roll but the RX never feels top-heavy or unsettled.

The steering carries the weight of the SUV but remains well-balanced and responsive. Overall, it’s a well-tuned machine that’s a pleasure to drive.

Maneuverability is a strong suit, too, thanks to a tight 11.8-metre turning circle and a clear, easy-to-use 360-degree camera system. Parking is easy-as-pie, which a lot of drivers will appreciate.

Once you've become accustomed to the strange, low steering wheel with its angular design the 308 GT Sport plug-in hybrid is superb to drive. The suspension is composed and comfortable, the handling is excellent, the steering is light and with the combination of both the electric motor and petrol engine, acceleration is good.

For those of you who haven't driven a plug-in hybrid before I think you'll like the quiet electric power at low speeds and the feeling of ‘instant' acceleration the electric motor adds, but compared to driving a regular petrol car the experience is much the same, just less noisy and smoother.

The petrol variant of the Peugeot 308 achieved low scores when it came to protecting its front passengers in ANCAP's frontal off-set crash test and it was for mainly this reason that the vehicle scored four out of  the maximum five stars in its ANCAP and equivalent European safety rating.

That said, Peugeot Australia has added more safety technology to the 308 than the European version of this car, such as a more comprehensive autonomous emergency braking (AEB) system as standard.

Along with AEB that can also detect cyclists and pedestrians, other standard safety tech includes lane keeping assistance, blind spot warning and rear cross traffic alert.

For child seats there are three top tether anchor mounts across the second row and two ISOFIX points on the outside rear seats.

There are front and side airbags for the driver and co-pilot, while curtain airbags cover the first and second rows.

The RX comes with a five-year, unlimited-kilometre warranty, which matches its key rivals but isn’t exactly class-leading by today’s standards.

Servicing is handled via a capped-price program, with each service costing $695. The intervals are well spaced at every 12 months or 15,000km, whichever comes first.

This Sports Luxury grade also includes a three-year complimentary 'Lexus Encore' membership, granting access to a handy phone app and member benefits at partners like Westfield and Ampol. On top of that, you get 24/7 roadside assistance for added peace of mind.

The 308 GT Sport plug-in hybrid is covered by Peugeot's five-year/unlimited-kilometre warranty.

Peugeot will cover the hybrid battery with an eight-year/160,000km warranty.

Servicing is recommended at 15,000km or 12 month intervals and it can be expensive. Peugeot says the first service will be $425, then second is $771, the next is $425, then at 60,000km the costs will be $900, then $439 for the following.
