vw fanlarının efsanevi motorlarından g60 ve g40 serisi hakkında bilgi paylaşmak istedim. malum sitemizde vw teknolojisini en dandik 1.6 8v ile eşdeğer görmeye çalışan bazı anti fanatikler mevcut.
g60 ve g40 motorlardan g60 mk2 golf ve döneminin vw modellerinde kullanılmış olup 1988 den 1994 yılına kadar üretimi yapılan 1.8 lt aşırı besleme 160 bg 225 nm tork sunan bir makinedir. g40 ise 1.3 lt aşırı besleme 116 bg 150 nm tork veren bir makinedir. çok sağlam ve uzun ömürlü olmş makinelerdir bunlar. yüklemeye karşı çok dayanıklı ve ciddi güçler elde edebilen makinelerdir.
ve bu makinelerde edinilen tecrübelerin sonucu da şimdiki tdi, efsane konumuna gelen 1.8 20v T ve en son torunu olarak 1.4 tsi ve TFSİ motorlardır.

1.4 litre 'Twincharger' Future use of technology
Whilst it may seem a long period of time since the last Volkswagen engine with the G-Lader supercharger was installed in a Polo in 1994, Volkswagen Group have been thoroughly utilising the forced induction knowledge learned from these G40 and G60 engines.
[edit] Diesel engines
Volkswagen Group now have a long-established 'knowledge base' from both forms of forced induction. They first utilised this technology with turbochargers in their TurboDiesel 'TD' engines. This then evolved into their highly regarded range of Turbocharged Direct Injection 'TDI' diesel engines, which are now available throughout virtually every car and light commercial vehicle in the Volkswagen Group.
Variants of their TDI engine have recently been used by Audi to great success in long-endurance prototype sports car racing, including the first diesel-powered victory at the 24 Hours of Le Mans in their R10 TDI, at the cars first attempt. SEAT have also tasted success in touring car racing, winning both the Drivers' and Manufacturers' categories of the 2008 and 2009 World Touring Car Championships, with their SEAT León TDI racing hatchback.
Turbochargers on diesel engines are now seen as the norm, from all automotive manufacturers, and it is rare to find an automotive diesel engine without turbocharged forced induction.
[edit] Petrol engines
[edit] Turbochargers
Turbochargers have also been of great benefit to recent petrol engines in the Volkswagen Group. Probably their most famous and widely used engine is their highly popular Audi-developed 1.8 litre 20-valve Turbo inline-four engine. This has been used in many of their mainstream, and high performance cars; such as the original Audi S3 and Audi TT, the Mk4 VW Golf GTI, the original Škoda Octavia vRS, and the original SEAT León Cupra R. This strong, and highly tuneable engine has won many prestigious awards, and is highly regarded by professional engine tuners and motorsports teams. Furthermore, this same engine is used in a very high state of tune in the one-make Formula Palmer Audi (FPA) open-wheeled racing series.
Volkswagen Groups' current range of Audi-developed Fuel Stratified Injection engines, again award winning, and again winning at Le Mans - continue to champion the turbocharger in petrol engines, and also include cylinder-direct fuel injection, making them not only powerful, but now also very fuel efficient.
Audi-developed straight-fives (including the 232 kW 2.2 Turbo from the Audi RS2 Avant), V6 engines (the B5 Audi RS4 280 kW 2.7 T V6), and even V8 engines (the C5 Audi RS6 331-353 kW 4.2 V8), have successfully used turbos, the latter two V engines as 'biturbo's. Current 'large capacity' Volkswagen Group users of turbos include Lamborghini-derrived Audi C6 RS6 5.0 TFSI V10 biturbo engine, and the Bugatti Veyron EB16.4 8.0 litre 736 kW sixteen cylinder 'quad-turbo' engine, which can achieve an astonishing (for a road-legal car) top speed of 406 kilometres per hour (252.3 mph)!
[edit] Superchargers
The supercharger has also seen a recent return in a petrol engine. First announced at the 2005 Frankfurt Motor Show, Volkswagen released the 1.4 litre TSI 'Twincharger' engine - which uses both a turbocharger, and an Eaton fifth-generation Roots-type positive displacement supercharger. Dependent on the state of tune, power output from this relatively diminutive engine ranges from 90 kilowatts (122 PS; 121 bhp), and can rise to 133 kilowatts (181 PS; 178 bhp) - which puts it on a par with a conventionally aspirated 2.3 litre engine. And once again, another Volkswagen Group engine winning a highly prestigious award, this time the "International Engine of the Year".[4]
And for larger displacement engines, the supercharger has been fitted to an all-new aluminium alloy 90° V6 engine,[5] which displaces 2,995 cubic centimetres (182.8 cu in). Now used in all current Audi four-door saloons and five-door Avants (Audi's name for an estate car) - from the Audi A4 upwards, along with the two-door Audi A5 coupé - it uses an all-new Eaton 'Twin Vortices Series' (TVS) Roots-type positive displacement compressor. This new blower features twin four-lobe rotors which are twisted 160-degrees. It is mounted on top of the engine within the 'Vee', pumping air directly into the inlet manifold. This new design of supercharger is said to reduce the noise, vibration, and harshness (NVH) of the engine. In 'standard' tune, this engine produces 213 kilowatts (290 PS; 286 bhp) at 4,850-6,500 rpm, and 420 newton metres (310 ft·lbf) at 2,500-4,800 rpm. However, a higher performance variant is fitted to the latest B8 Audi S4,[6] and in this car, produces 245 kilowatts (333 PS; 329 bhp) at 5,500-7,000 rpm, and 440 newton metres (325 ft·lbf) at 2,500-5,000 rpm - which makes this new S4 more potent than its immediate predecessor, with its 4.2 litre V8. This engine is also scheduled to be fitted to a new hybrid version of the Volkswagen Touareg.[7]
