Peugeot will showcase the plug-in hybrid QUARTZ Concept for the Crossover segment at the 2014 Paris Motor Show. The QUARTZ is based on the same EMP2 platform that underpins the new 308. The composite structure and bonded panels save weight but bring stiffness, enabling the engineers to remove the central B pillar and create scissor doors. A retractable step further eases access.
QUARTZ uses a plug-in “HYbrid” drive system comprising a gasoline engine supplemented by two electric motors. A 1.6-liter THP 270 engine developed by PEUGEOT Sport is mated to a six-speed automatic transmission. The four-cylinder engine delivers 330 N·m (243 lb-ft) of torque, with a specific output of nearly 170 hp per liter.

|Peugeot is also showcasing its 208 HYbrid Air 2L Demonstrator at next month’s Paris Motor Show. (Earlier post.) The 2L stands for two liters per 100 km, equivalent to 118 mpg US, and is based on a production version of the Peugeot 208 1.2-liter PureTech 82 hp 5-seater Hatchback.|
|Peugeot’s Hybrid Air (earlier post) is a full-hybrid solution combining compressed air and hydraulic power, with no battery required for energy storage. Hybrid Air combines the PureTech gasoline engine; a compressed air energy storage unit located beneath the trunk; a hydraulic pump/motor unit in the engine bay; and and an automatic transmission with an epicyclic gear train.|
The front axle is also driven by an 85 kW electric motor with direct drive. This charges the 400V battery during deceleration and assists the combustion engine with gear changes. The rear axle also features an 85 kW electric motor for propulsion and battery charging.
There are three driving modes:
ZEV can cover up to 31 miles (50 km) on a single battery charge using the plug-in battery;
Road mode uses the combustion engine and front electric motor to enhance driving pleasure and maximise battery charging during deceleration;
Race mode harnesses the power of the engine and both electric motors to get the most out of the chassis with a limited-slip differential for increased driver engagement.
The front axle of the QUARTZ employs bespoke MacPherson struts. On the rear there’s a multi-arm suspension arrangement including the on-board electric motor. The pneumatic suspension automatically adjusts ground clearance between 300 and 350 mm. This is controlled by an optical system that uses cameras linked to the satellite navigation to read the road and anticipate changes in its surface.
At 4.5m long and 2.06m wide, the QUARTZ has an athletic stance on the road that’s further emphasized by its long hood and louvres that help improve airflow to the engine.
A glass roof flows towards the rear wings and incorporates two spoilers to further enhance its aerodynamic design. Wheel spokes have been kept to a minimum thanks to the strength of the materials and they’re covered with composite flaps. These optimize aerodynamic flow and help cool the brakes to ensure improved heat resistance.
The QUARTZ Concept is the first vehicle to employ digitally woven textile. This innovative process can create large and complex components that can be used as soon as they come off the machine. No cutting is required meaning no waste. The textile is woven with polyester fibre from recycled plastic water bottles.
The PEUGEOT i-Cockpit keeps everything at the driver’s fingertips. The compact steering wheel is inspired by competition models with controls embedded in it. This allows drivers to use the indicators, change driving modes and shift gears without taking their hands off the wheel. The head-up display provides a large, configurable screen with a central 45-degree polycarbonate strip to show additional information. The instrument panel is on both sides of the small steering wheel and the head-up display is angled towards the driver to ensure easy access to the toggle switches.
