The first generation of the Gallardo was powered with an even firing 4,993 cc (5. 0 L) 90 degree V10 engine generating a maximum power output of 500 PS (368 kW; 493 hp). The Gallardo offers two choices of transmissions, a conventional (H-Box) six-speed manual transmission, and a more advanced six-speed electro-hydraulically controlled semi-automatic electrohydraulic manual transmission, which Lamborghini abbreviates to "E-gear". The "E-gear" allows the driver to change gears much faster than they could with a manual transmission. The driver shifts up and down via paddles behind the steering wheel, but can also change to an automatic mode via the gear selector located in place of the gear shift lever. The vehicle was designed by Luc Donckerwolke and was based on the 1995 Calà prototype designed by Italdesign Giugiaro.
