Description
Model Variants

The Lola B05/52 was the spec car used by the series from the 2005–06 season to the 2007–08 season.

It was powered by Zytek engines, and ran on Cooper tyres. The former chassis is now used in the Euroseries 3000, starting in 2009.

Chassis

The chassis, designated Lola A1GP, is made and designed by Lola Cars. The A1 Car's carbon fibre skin cloaks a core of aluminium honeycomb. Based on bionic engineering principles found in nature, the hexagonal honeycomb provides remarkable strength for its weight, and has progressive deformation properties in response to an impact, which contributes to driver safety. In addition, drivers are protected by FIA-approved side intrusion panels that protect them from lateral impacts.

Engine

The engine for the cars was developed by Zytek Engineering. The 3.4-litre V8 unit is capable of delivering 520 bhp (550 bhp in powerboost mode). Each engine must be very durable, as it must last a whole season. The engine only weighs 120 kilograms, making it one of the lightest 3.4-litre engines ever made.

Technical specifications

The car has an overall length of 4833 mm, with a long wheelbase of 3000 mm and a wide track of 1476 mm (front) and 1468 mm(rear). Its total weight amounts to 695 kilograms, without the driver and the fuel.

Suspension

The front and rear suspension is of a double wishbone and pushrod operated twin coil over damper construction. Adjustable ride height, cambers and toe, as well as anti-dive and anti-squat made to optimise drive control.

Clutch

A two-piece carbon clutch was tailored especially for the car to handle the exceptional torque of a racing engine with up to 550 bhp (410 kW) and the two racing starts per weekend. The unit combines lightweight construction with durability and bullet-proof reliability. The A1 car's gearchange is by electronically automated shifting of a six-speed paddle shift transmission—peak loads at full throttle could literally shred a lesser clutch. The two-piece carbon clutch can take the load, even when the driver changes up with the PowerBoost activated. In hot and cold testing the clutch proved faultless. The clutch operation of A1GP car was operated by the foot-pedal on the very left side.

PowerBoost

The PowerBoost button on the A1 car allows the engine to reach its maximum of 550 bhp (410 kW). When used at the right time, this feature can encourage overtaking. For the PowerBoost to activate, the throttle position must be above 80% and the speed more than 60 km/h. The button must also be depressed to continue on PowerBoost mode. However, the PowerBoost automatically deactivates itself if the throttle falls below 40%. Each driver only has a limited number of uses of the PowerBoost function. The driver can only use it four times in a sprint race and eight times in a feature race. Once these maximum allocated uses of the PowerBoost have been used, the system is disabled until the end of the race, after which Zytek engineers reset the system for the next race.
