Forget every single thing you know about the old Peugeot 3008, because this is none of those things. This is the all new 2018 Peugeot 3008 GT, a luxury performance, mid-sized SUV with a complete new look and feel.

For starters, a 2.0-litre diesel pushes this shiny new Peugeot around, pumping out 133kW of power and 400Nm of torque. While that sounds wonderful, far more interesting is the 4.8L/100km fuel economy – and no, that’s not a misprint.

It really does push those kind of numbers. While some days of hard driving saw numbers more in the mid-6L range, when we drove it like someone who wasn’t doing a road test might, it stuck between 4.8 and 5.3L/100km, which is impressive.

Coupled with a six-speed auto gearbox, the 2018 Peugeot 3008 GT is front-wheel-drive only, but it’s a pretty effortless vehicle to drive. When you switch it to sport mode, it gets plenty of grunt up and accelerates harder than we were expecting.

That said, the power plant in the GT doesn’t sound fantastic when sitting idling, think tradie ute, but get in and drive it before you pass judgement, because on the road, it’s one of the quietest diesel’s we’ve ever driven, and it never seemed to do it tough, either.

Gear changes, especially down-shifts, can be a bit ordinary at low speeds. But overall, the GT performed exceptionally well. It looks good outside, too, with what can best be described as a very unique-looking front grille.

It rides on 19-inch, Boston two-tone, diamond-cut alloy wheels, which don’t help the ride a great deal. It also features aluminium roof bars and door mirror LED puddle lights that feature the Peugeot Lion.

It’s also loaded with magic-wash front windscreen wipers (as in, the water washer disperses through the wipers), full LED headlights and fog lights, and rear LED ‘claw effect’ lights with a daylight function.

Jump inside and before we talk about the actual interior, we need to discuss the technology the Peugeot 3008 GT is bundled with, because it’s amazing.

From the massage system for the driver, to the air deodoriser that operates automatically to keep the 3008 GT smelling fantastic, the French car maker has literally thought of everything and made it all work together harmoniously.

It’s delivered under the guise of Peugeot i-Cockpit, which also provides the super-cool looking compact sports steering wheel and an 8-inch touchscreen infotainment system, along with the configurable 12.3-inch, head-up digital instrument display.

The infotainment system features 3D navigation, Wi-Fi, Bluetooth, USB, DAB, Apple CarPlay, Android Auto and Mirrorlink. You can even open emails off your phone, receive text messages and, using voice recognition, send some responses.

Getting away from the technology and looking at what’s inside the 3008 GT, the first things you'll notice are the quilted leather seats, the monstrous panoramic retractable glass roof, oh, and the little hints of luxury everywhere.

Everything is electric, or at least it feels that way, with electric folding door mirrors, electric parking brake (includes hill assist), and an electro-chrome, auto-dimming rear-view mirror. There’s electric front seats and seat warmers, too.

The dashboard, and front and rear door panels, are finished in grey Alcantara leather. The front and rear centre consoles feature two cup holders. There’s loads of boot space too, some 591L in all.

The 2018 Peugeot 3008 GT features a ‘magic flat’ split-fold rear seat with boot-accessible controls. Even the front passenger seat can be laid flat to increase the sheer load space 1670L, should you need it.

On the safety front, there’s active blind-spot detection, active lane-keeping assistance, adaptive cruise-control with stop function, advanced driver-attention alert, distance alert system, electronic stability control and a lane-departure warning.

As an added bonus, autonomous emergency braking is now standard across the 3008 range. It operates by detecting stationary or moving cars and trucks, as well as pedestrians, and provides braking assistance to avoid collision.

In the 3008, the system kicks in at 5-140km/h if another moving vehicle is detected, under 80km/h if a stationary vehicle is detected, and below 60km/h if a pedestrian is detected -- slowing the car to prevent an accident.

Peugeot also offers smart-beam assistance, six airbags, and speed-limit recognition and recommendation. For parking, there’s 360-degree reversing and front cameras, and the convenient city park system, which helps you park at either 90-degrees or parallel.

It’s got some stiff competition, with serious players in the same space including the Mazda CX-5, VW Tiguan, Kia Sportage, Hyundai Tuscon, Renault Koleos, Subaru Forester and the Ford Escape.

But as the top-of-the-line in the 3008 four-variant lineup (the other options are the Active, Allure and GT-line), it has the props to be a better option on luxury and technology alone, than most of its competitors.

The 2018 Peugeot 3008 GT hits the road at $49,490 plus on-roads, and comes in Pearl White, Hurricane Grey, Platinum Grey, Perla Nera Black, Metallic Copper, Magnetic Blue Amazonite and Ultimate Red.

It also comes with a three-year warranty and roadside assistance program.
