Ferrari 458 to get in Geneva Twin Turbo V8 engine
Ferrari 458 to get new twin-turbo V8 | Autocar
Ferrari will launch a twin-turbocharged V8-powered replacement for the 458 Italia at the Geneva motor show next spring, marking the start of a new era under chairman Sergio Marchionne.
The new car is a reskin of the aluminium platform that underpins today’s 458. The car’s project name is 142M — M for modified, 142 being the project number of the 458.
The new two-seater is expected to break fresh technical ground for a ‘mainstream’ mid-engined Ferrari by featuring a twin-turbo V8. It is based on the California’s 3.8-litre unit and test mules have been running it for some time.
Modified with dry-sump lubrication compared with the wet sump in the California, the V8 will have a capacity below 4.0 litres to comply with an influential Chinese tax threshold. Currently, the 4.5-litre V8 in the 458 suffers high taxes in China, hampering sales.
The California’s V8 has a capacity of 3855cc, based around an 86.5mm bore diameter, shared with the 3798cc Maserati version. To raise capacity, the California’s has a slightly longer stroke.
For the new 458, Ferrari must select the V8’s stroke carefully to ensure ‘over-square’ dimensions for a short stroke to promote peak power delivery at high engine revs.
A 4.0-litre capacity, for example, would be delivered with a relatively long stroke of 85mm, very close to the 86mm bore. In comparison, the outgoing 458 engine has a 94mm bore and a much shorter stroke of 81mm.
Ferrari may even need to select a stroke of 75mm, equivalent to just 3.5 litres, to maintain similar engine geometry to the rev-happy V8 in today’s 458. However, whether that is sufficient to generate the required power is a point for discussion.
The target car for the new 458 will be the 641bhp McLaren 650S and there are suggestions the Ferrari might be rated at 666bhp. To develop 666bhp from under 4.0 litres, the new V8 will have to produce 168bhp per litre, and from 3.5 litres 192bhp per litre.
To achieve that, the engine will feature a relatively high 12:1 compression ratio, aided by Ferrari’s ‘ion’ knock detection system, which adjusts combustion conditions individually in each of the eight cylinders.
The engine’s capacity is also likely to form the car’s name, a tradition started by the 206 Dino in 1968 — a 2.0-litre V6. A 3.5-litre V8 opens up the possibility of 358, a 3.8-litre 388 and a 4.0-litre 408. By adding a T, Ferrari might denote turbocharging. However, experience suggests that Ferrari is just as likely to opt for a new naming direction.
Other aspects of the new 458’s engine design are likely to diverge from the California’s, too. “Do not expect the same induction system as the California,” one source told Autocar.
One possibility is an electrically powered turbo. Ferrari is known to be experimenting with this technology, although it requires a 42V electrical system, which is probably too expensive to reverse engineer into an existing architecture. More likely is a conventional twin-turbo set-up, with two low-inertia turbo units that allow instant throttle response and high peak power at the expense of torque.
One of the challenges facing Ferrari’s powertrain engineers is how to reliably match a 650bhp-plus, 550lb ft-plus torque output to the seven-speed Getrag ‘7DL750’ dual-clutch automatic gearbox employed on all models from the California up to LaFerrari. Peak torque from the California’s 553lb ft V8 was set at the ’box’s limit and is only delivered in seventh gear. In the six lower gears, it’s limited to 400lb ft.
Autocar understands that developments are in the pipeline for the Getrag ’box, but whether that means beefier internals or an extra gear, for example, is unclear.
Styling is said to be the work of the in-house Centro Stile Ferrari design chief Flavio Manzoni and it is likely to be evolutionary. Developments in aerodynamics are likely to lead changes, with the front-end graphic centred around aggressive twin intakes.

my list of best sounding Ferraris, not in any order: F50, 355, 360CS, 458, Enzo, LaFerrari
for race cars - F50GT, 599XX, Enzo FXX, to name a few
more cars can make the list with aftermarket exhaust, the Testarossa is one of my fav F-cars but was never known for its sound - have a listen to one with Fuchs exhaust and that is pretty nice.
not including older cars cuz I don't know their sounds as well
moral of the story, there are many Ferraris that are not known for their sound

2016 Ferrari 458 MM Speciale

Press release...
Ferrari has unveiled its latest One-Off creation during the car’s first shakedown on the Fiorano circuit in the hands of Ferrari’s chief test driver Dario Benuzzi and the car’s enthusiastic British owner.
Designed in-house by the Ferrari Styling Centre, the 458 MM Speciale was built on the chassis and running gear of the 458 Speciale. Stylistically, the client was looking for extremely sporty lines and specified a ‘visor’ effect for the glasshouse: a black-painted A-pillar, very much in the style of the 1984 Ferrari GTO, helps provide a wraparound solution between the windscreen and side windows which thus meld into single, seamless glass surface. This solution simultaneously lowers the roofline and lends an aerodynamic sleekness to the full volume of the swept-back C-pillar.
Finished in Bianco Italia and complete with a livery that pays homage to the Italian flag, this unique coupé features all-new bodywork, handcrafted in aluminium with composite carbon-fibre bumpers front and rear. The 458 MM Speciale also boasts a new side air scoop, one of the most distinctive elements in an extensive revision of the aerodynamic package.
The radically modified aerodynamic solutions are already evident on the front of the car, where the bodywork hugs the coolant radiators which are more steeply inclined and mounted closer together than on the 458 Speciale. The side intakes were devised to allow direct additional cooling of the engine bay to compensate for the different rake of the rear. The tail features a spoiler which balances the downforce evenly and also completes the theoretical beltline that sweeps back along the side from the front wheelarch, giving the car a powerful and athletic stance.
The 458 MM Speciale sits on specific wheels exclusive to this very unique car, and an additional touch is the adoption of modified front and rear light clusters. Inside the cockpit upgrades include to an enhanced audio system and trim definition to match the owner’s specific wishes. The Cioccolato leather upholstery with white stitching is elegantly accented by a slew of neat touches such as the satin white rings around the tunnel controls.
