V5 engine: the short but curious story of a quirk of Volkswagen
Yes, Volkswagen has a peculiar fixation with engine design and for decades like to take the foot off the pot with bets as risky as engines W. But in history there are so peculiar engines or more than propellant W12 still remains, the W16 huge Bugatti Chiron or VR6 revered by many. There was a time that would reinvent Volkswagen 5 cylinder, not conventionally, but creating a 2.3 V5 engine exotic that few know and have seen even less.
5-cylinder engines are mechanical characterized by low employment in automotive history, but whenever they have used has been realized through a design in line with to offer the best balance in terms of vibrations. Lack of support is found in the best balanced inline-6 and the versatility of the 4 online. Despite this and although Mercedes and Volvo also used them for a long time, still survive today 5 online hand Audi 2.5 TFSI and block used by RS3 and TT RS Q3 RS.
But all this did not matter to Volkswagen in 1997, despite having 5 Audi online available, he decided to start from scratch and create a V5 engine, yes, 5-cylinder V configuration close to 15 ° between thwarts but with a single head. Thus was born a peculiar engine, even more than the VR6 derived, for Volkswagen created an ultra-compact block where five cylinders working in a similar space needed a conventional 4 in line. The first generation of this engine 2.3 V5 reach the market in specification 150 hp with cylinder head 10 valves - two per cylinder - and the aim of being an intermediate step on benefits to move the Golf IV GTI, VR6 leaving a step above variants being marketed in 2.8 liter and 204 hp first, and 3.2 liters after 240 CV for the most powerful and sports specification was Golf R32.
The V5 engine ever too stressed in Volkswagen, and that was integrated in the ranges of Golf, Bora, Beetle, Passat and even the SEAT Toledo in an attempt to raise the cache of Spanish sedan that militated in a different current segment and enjoyed considerable commercial success for that so. The 2.3 V5 150 CV - the original block - wanted to offer something really new as mechanics, and despite its exotic design, its operation was smooth and progressive, yet was characterized by a linear power delivery where missing low and to a lesser extent higher, but with remarkable means guaranteeing good recoveries. To this must be added that it was a glutton for by its features motor.
After the first version of 150 hp, Volkswagen not ceased in its efforts and updated propeller V5 releasing a new cylinder head with valves 20 - cylinder 4 - variable distribution and management optimization of ignition and injection. In the end the fact that most stood out in this evolution was the gain of 20 bhp, He led the V5 2.3 to 170 hp at 6,200 rpm, but the real work of Volkswagen had focused on improving the character of the engine and reduce consumption. The V5 engine had improved, offering more where once wavered, But that was not worth anything to survive.
Parallel Volkswagen had been developing the 1.8 20V Turbo, a four-cylinder, turbocharged and with five valves per cylinder exceeded throughout the 2.3 V5 and offered a modular configuration to permit different power levels, support different transmissions and even ability to be combined with AWD despite be a transverse engine. The V5 which had been updated signed his sentence and in no time was disappearing from the beaches in favor of a more explosive 1.8 Turbo and lower consumption in the memory only would the few models who installed this exotic V5 and sound of this engine that became one of his best hallmarks.
