Ferrari's Future

The technology behind the potent new 390bhp V8 engine and six-speed F1-style Cambiocorsa gearbox designed by Ferrari for Maserati's Spyder and Coupe will find its way into the next generation of Ferrari road cars. The F50 replacement, codenamed FX and due to make its debut later this year, will be fitted with a super-fast version of the paddle-shift automated manual transmission. 'The new F50 gearbox will be two to three times faster than the existing Cambiocorsa,' says Ferrari-Maserati powertrain engineer Mauro Rioli. The improvement is due to a combination of faster computer hardware and software, and to improvements in the electro-hydraulic selector mechanism. Features of the all-aluminium Maserati V8 will also find their way into Ferraris.

The Cambiocorsa 'box, which debuted on the Maserati Spyder last year, is already one of the fastest automated manuals fitted to a roadgoing car and underscores Ferrari's commitment to the technology. Two years ago, Ferrari engineers confirmed they were working on new-generation paddle-shift systems that could change gear up to eight times faster than the current 360 Modena F1 system, by performing sotware tasks in parallel rather than sequentially, and by combining more powerful processors with revised mechanics. Rioli claims refinement will also improve. 'When you improve the speed, you also improve the comfort,' he says. The existing Cambiocorsa will be used on the new Quattroporte Maserati launched next year and there will be no conventional manual option.

The new V8 has drawn heavily on F1 technology with its short block, integrated dry-sump pump and small clearances between the crank and the bottom of the sump. 'It is clear,' says Rioli, 'that this activity will be applied to Ferrari engines.'

The next Ferrari V8 could share the same bore-centres as the new Maserati engine which started development in 1996. Internal dimensions are in proportion to the existing 3.5-litre, 90 degree V8 of the 360 Modena engine which has a bore of 79mm compared to 80mm for the Maserati. Producing a shorter stroke 3.5-litre version would therefore be relatively simple but the engine characteristics will probably remain quite different. In a classic GT car like the Maserati, the emphasis is on torque, the 4.2-litre V8 developing 333lb ft at 4500rpm.

The current Ferrari engine is smaller and more peaky, producing 400bhp at 8000rpm and 276lb ft at 4750rpm. As a result, next- generation Ferrari engines are likely to stick with deep-breathing five-valves-per-cylinder heads rather than the four valves of the Maserati.

Ferrari is researching direct injection but Rioli claims that supercharging isn't an option. 'I think supercharging will end fairly soon,' he says, 'as efficiency is lower than with turbochargers.' But Ferrari is unlikely to return to turbos either, at least in the near future: 'You have to drop the compression ratio significantly and you lose efficiency.' However, turbocharging may one day be considered in conjunction with direct injection, which would allow a higher compression ratio off-boost. If the trend towards ever higher ouputs continues, Ferrari is ready to consider all options.
