Despite gloomy economic conditions and ever-increasing oil prices, it looks like the American manufacturers have an emerging confidence. Their message seems to be that people might have an ultra-efficient hybrid or range-extender for everyday use but, while they still can, some of them want to occasionally enjoy V8 power too.
Chevrolet has also joined in, unveiling the range-topping Camaro ZL1 in Chicago. Taking its name from a limited run of Camaros built in 1969 with all-aluminium racing engines, the new ZL1 features the same 6.2 litre (376 cubic inch) V8 motor that powers the current SS spec Camaro, but with a few fundamental differences.
A sixth-generation intercooled Eaton supercharger, high-strength pistons and heat-resistant cylinder heads all combine to lift output from the 426 bhp (317 kW / 431 PS) of the SS to an estimated 550 bhp (410 kW / 557 PS). Torque is also expected to show a similar increase, rising from 569 Nm (420 lb/ft) to 677 Nm (550 lb/ft).
However, with the car still undergoing development before its market launch in early 2012, final power and performance figures for the ZL1 have yet to be determined.
The only transmission choice will be a Tremec TR-6060 six-speed manual gearbox, connected to the engine via a twin-disc clutch to cope with the extra torque and deliver smoother gear changes.
It might be assumed that the hottest Camaro will be good only for quarter-mile runs, with even the slightest bend quickly exposing its shortcomings. But Chevrolet is keen to challenge such preconceptions, stating that the ZL1 is ‘intended to reach optimal lap times on top road-racing circuits and excellent driving dynamics on the street.’
To help achieve this, the retuned suspension features Magnetic Ride Control that adjusts the behaviour of the dampers. There’s also a heavy-duty limited slip differential, while a new electric power steering system is said to offer more precision and driver feedback. The braking system has been developed in partnership with Brembo, and includes six-piston calipers for the larger front discs.
All of which sounds very promising, but only the first road tests will confirm whether or not the ZL1 lives up to Chevrolet’s bold claims.
Visually, the aesthetic throughout is that form follows function. Compared to lesser Camaros, changes comprise a redesigned bonnet with air extractors set into a carbon fibre centre panel, a more aggressive front fascia and splitter, rear diffuser, rear spoiler and lightweight 20” forged aluminium wheels.
It was announced last year that Chevrolet would start officially importing the Camaro into the UK. However, there’s still no sign of it, so it remains to be seen if the ZL1 will ever make it across the Atlantic.
