Big question of the day ????

[sequoias]

I means H6 engines. The 1948 Tucker Sedan started with a H6 then Chevy Corvair in 1960s and later Porsche 911 in 1965? to present. Yes, Porsche worked on the flat 4 engines for VW during WWII.

Got it. I thought you meant the flat engines in general.

Funny, Porsche got an idea for Flat 6 engine from Chevy Corvair but I guess the Chevy Corvair copied the Flat 6 engine from 1948 Tucker Sedan.

Karl Benz, German engine designer, invented the world's first Flat engine in late 1850's (not exact year).

Note: the Flat 6 engine in a 1948 Tucker Sedan, is considering the largest gasoline powered flat engine, size 334.1 cid = 5.5L.... 4.50" bore X 3.50" stroke, 7.0:1 compression ratio, rated 166 HP and 372 lb. ft torque.

Oh yes, I remembered about Chevy and I seem that from hot rod show in the real life. Sad, Chevy stopped made them due engine problem?

Porsche and Subaru still use them for today.

Chevy stopped the Corvair completely due to bad publicity caused by Ralph Nader's book "Unsafe at any speed".

The Corvair's problem was not necessarily the engine, but the whole car was designed badly. All the weight was in the rear, and if you as much as farted while going around a curve, you would lose control easily.

It is too bad, since the Corvair was a cool car. Their engines have been known to last 500,000 miles.

VW, Porsche, and others have engineered their rear-engine cars to handle better. Want a flat-six? Get a Subaru.

Corvair has poor suspension geometry on the corners, smooth ride on straight road. If you turn left on the curve road at medium to high speed, the left front tire get a large negative camber (toward inside) and right front tire get a large positive camber (face outside of the vehicle' side), poor tire tread contacts on the surface. They used same lengths of upper and lower control arms. No good.
Todays vehicles almost have zero positive or negative cambers on the corners, good tire treads grip (full tread contacts). Short length upper control arm and long length lower control arm. Popular front suspension design in domestic cars is Ford Mustang II or Pinto

I already have Subaru since 2002 but it's EJ25.
