How And Why Honda And Volkswagen Made Shockingly Successful (yet Still Doomed) V5 Engines

Trending 9 hours ago

Like each engines, five-cylinder engines person their cons, but they person besides had their moments successful nan sun, particularly successful Volkswagen Group's products. The company's I5 motors were a comparatively communal show nether nan hoods of various Golfs, Jettas, Beetles, and Passats good into nan 21st century. The aforesaid is existent for Audi entries ranging from nan original Audi Quattro of 1980, to much modern high-performance RS models. In fact, VW was truthful enamored of nan five-cylinder motor that it moreover put a V5 into accumulation vehicles — and it's nan only automaker capable to make that claim. But that wasn't nan only V5 to find immoderate benignant of success.

Honda built its ain type successful 2002, though it was constricted to usage successful nan company's MotoGP racing bikes — wherever it was responsible for Team Honda winning aggregate championships successful nan early 2000s. Now, contempt nan galore differences betwixt VW's and Honda's motors, they did extremity up having thing successful common: some were destined for eventual failure, partially owed to nan inherent issues pinch V-type engines moving an overseas number of cylinders, and partially because of different powertrain improvements that were capable to capable nan spread betwixt emblematic four- and six-cylinder motors.

Consider that five-cylinder engines primitively took purpose astatine nan Goldilocks area betwixt nan different two, targeting much powerfulness than a four-cylinder centrifugal but much ratio than a six-cylinder engine. Well, nowadays, that would beryllium nan cleanable mounting for a smaller turbocharged motor that could present those results without nan drawbacks aliases disbursal of a five-cylinder mill. 

VW and nan narrow-angle V5

For Volkswagen, nan communicative starts successful nan 1980s pinch its VR6 engine, which hardly qualifies arsenic a V engine. The perspective betwixt nan cylinder banks was a specified 15 degrees, meaning it was constrictive capable to usage 1 cylinder caput for each cylinders — alternatively than nan accustomed V-engine configuration of having abstracted cylinder heads for each bank. The adjacent shape came erstwhile Volkswagen was looking for a somewhat smaller motor package to fresh into much of its vehicles, and simply decided to region 1 cylinder from nan VR6. 

Okay, nan process was a small much analyzable than that because nan motor was now retired of balance. Volkswagen claimed nan constrictive V-angle helped mitigate nan problem, pinch immoderate thief from a counterweighted crankshaft and a dual-mass flywheel. However, nan consequence was a 2.3-liter motor primitively tin of 150 horsepower and 154 pound-feet of torque successful nan 1997 VW Golf. Upgrades accrued output to 170 horses and 168 pound-feet of torque for the 2000 exemplary year, but by then, turbocharging was already proving a amended tactic. Indeed, nan VR5 motor of nan clip couldn't apical nan output of nan company's 1.8-liter turbo-four motors. Yet it was heavier, much expensive, and little efficient. 

Nor did it ever make it to nan United States. While nan VR5 was disposable for Euro-spec versions of nan Bora/Jetta, Golf, and Passat, nan company's U.S. products featured nan accepted I5 instead. Even today, erstwhile nan VW Golf R is celebrating its 25th anniversary pinch a caller five-cylinder engine, it's 1 of nan Volkswagen Group's I5s — borrowed from nan existent Audi RS3.

Honda and nan wide-angle V5

The Honda we cognize coming sewage its commencement building motorcycles successful post-World War II Japan, and two-wheel proscription has remained a immense portion of nan company's business ever since. The history-making Honda Super Cub, first introduced measurement backmost successful 1958, is considered nan best-selling motorcycle successful nan world, pinch much than 100 cardinal produced — and counting.

Along nan way, Honda followed a acquainted book for makers of motorized proscription and turned to racing to boost its beingness moreover further — and 1 of its astir successful machines turned retired to beryllium a V5 motorcycle called nan RC211V. It was specifically engineered for nan 2002 motorsports season, erstwhile nan MotoGP classification was first introduced. Now, this was besides during nan era erstwhile four-stroke motorcycle engines were becoming popular, and nan MotoGP people was developed pinch four-strokes successful mind. The inaugural season, however, saw a adjacent magnitude of experimentation: Five manufacturers ran four-stroke motors successful 2002, and they utilized 4 different motor configurations.

Honda's was a 990-cubic-centimeter V5 pinch a immense V perspective of 75.5 degrees, and it was mounted transversely, pinch 3 cylinders facing beforehand and 2 successful nan rear. The ample perspective kept nan setup balanced without nan request to adhd a equilibrium shaft, which would besides person added a weight punishment into nan mix. Led by No. 1 rider Valentino Rossi's 11 victories, Honda's V5 motorcycle recovered its measurement to nan winner's circle successful 14 of nan year's 16 races. Yet erstwhile MotoGP rules changed again for 2007, nan V5 nary longer fresh into either Honda's plans aliases nan caller classification scheme, and that was nan last play for Honda's "famous five."
