Peugeot 3008 Crossover bypasses four-wheel drive in favor of Bosch-developed Grip Control.  (Newspress)

Peugeot's 3008 crossover model is based on the company’s Platform 2 architecture, which it shares with the 308 and Citroën C4. The 3008 introduces a number of new technologies and will be available with the company’s Hybrid4 hybrid drive system, first seen at the Paris Show last October, in the next three years.

The 3008 will be powered by a range of engines comprised of two gasoline and four diesels units. Both gasoline engines displace 1598 cm³. The 88-kW (120-PS) variant is Euro-V compliant, as are the two 1997-cm³ diesels producing 110 and 120 kW (150 and 163 PS), respectively. The Euro-IV compliant engines are the 110-kW (150-PS) gasoline engine and the 80-kW (109-PS) diesel. Six-speed transmissions are fitted to all models except the 110-PS (81-kW) gasoline engine, which is equipped with a five-speed transmission. The 110- and 163-PS (81- and 120 kW) diesels are available with a six-speed automated transmission.

The car sets out to combine the features of an MPV, SUV, and hatchback. At the same time, Peugeot decided against offering the car with a four-wheel-drive option. Instead, in partnership with Bosch, the company has developed Grip Control. The optional package is offered with mud and snow tires and is effectively a revised traction-control system within the electronic stability control ECU.

The system offers five modes: Standard, Snow, All Terrain, Sand, and ESP Off. Standard is designed for regular road-going conditions. Snow to offer the best grip conditions for both front wheels when driving off. All Terrain will transmit optimum torque to the wheel with the most grip, while permitting a high degree of slip to the other wheel. Sand mode allows some wheel slip on both wheels simultaneously and will revert to standard mode if speeds exceed 120 km/h (75 mph). ESP Off can disengage the ESP system at speeds up to 50 km/h (31 mph).

A second option available with the most powerful gasoline and diesel engines is Dynamic Roll Control, developed with KYBSE. The system is a passive hydraulic system built into the rear suspension crossmember. It consists of a floating piston and hydraulic compensation reservoir pressurized to 20 bar (290 psi) and links the two rear shock absorbers. In cornering or rapid changes of direction, the system locks the piston and therefore helps to counter roll. The piston is free to move when the vehicle is traveling in a straight line and tends to counter suspension bounce in a more conventional way.

Peugeot has applied laser welding to the door frames and parts of the rear structure. This not only helps body rigidity but has also allowed some 5 kg (11 lb) to be removed from the body shell weight.

To reduce the front overhang to a minimum, Peugeot has incorporated a Bogé impact absorber. This consists of two conical impact absorbers fitted between the impact-absorption beam and the chassis leg. In an impact, the system permits a controlled deformation by way of a sacrificial collapse of the system to preserve the chassis leg.

To contain weight, the chassis leg and bonnet are constructed from aluminum, and high-strength steels make up some 12.5% of the body weight. Composite front wings are used, and the optional panoramic glass roof is 5 mm (0.2 in) thick, equating to a weight saving of around 5 kg (11 lb) compared with glass of conventional thickness and technology.

To provide a comfortable steering wheel angle with the high driving position of the 3008, Peugeot has incorporated an additional universal joint in the steering system.

The body shell measures 4365 mm (171.9 in) long, 1837 mm (72.3 in) wide, and 1639 mm (64.5 in) tall on a 2613-mm (102.9-in) wheelbase. Front and rear overhangs measure 916 and 836 mm (36.1 and 32.9 in), respectively. In aerodynamic terms, Peugeot claims a Cx factor of 0.296.

Split tailgates were much in evidence at the Geneva Show, but the 3008 adopts a conventional approach with a top hinged upper section and bottom hinged lower section capable of supporting an evenly distributed 200 kg (440 lb). The luggage compartment floor can be set in three different positions to provide load flexibility.

Flexible seating is also part of the 3008 package. The rear seat is split 60:40, and the adjustable trunk floor height ensures that, when folded, the rear seats can offer a surface flush with the floor. The front passenger seat can also be folded level with the rear seats, to open up 1241 L (43.8 ft³) (VDA) of luggage space, compared with 432 L (15.3 ft³) (VDA) with all seats in place.

Driver convenience features include a head-up display showing speed, cruise control, and distance alert information. The radar-based distance alert system warns the driver if the car is too close to the car in front. An automatic electric parking brake will be part of the regular equipment package.
