2009 Cadillac Converj Concept

CONVERJ: THE “CADILLAC” OF ELECTRIC VEHICLES

A thermally managed battery pack contains more than 220 lithium-ion cells that provide the primary power to drive the Converj electrically up to 40 miles without using fuel or producing tailpipe emissions. The battery is integrated into the Converj’s chassis and stores electricity from the grid when the vehicle is plugged in. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet. When the battery’s energy is low, the Converj seamlessly switches to extended-range mode.

Chassis

Ferrari 458 Italia

ITALIA - Ferrari’s innovative new V8

The Ferrari 458 Italia’s Pininfarina design provides further evidence of the complete departure from the past that this new car hails. The Ferrari 458 Italia has a compact, aerodynamic shape, underscoring the concepts of simplicity, efficiency and lightness that inspired the project. As with every Ferrari, the car’s styling has been very heavily influenced by the requirements for aerodynamic efficiency, as can be seen from the downforce of 140 kg at 200km/h generated by the new model. The front features a single opening for the front grille and side air intakes, with aerodynamic sections and profiles designed to direct air to the coolant radiators and the new flat underbody. The nose also sports small aeroelastic winglets which generate downforce and, as speed rises, deform to reduce the section of the radiator inlets and cut drag.

Performance
Acceleration (0-100 km/h) <3.4>
Emissions 320 g CO2/km
Fuel Consumption 13.7 l/100 km
