V8 - An engine with 8 cylinders, arranged in 2 banks of 4, forming a V shape.
V8’s are famed for the prodigious power output, and delicious exhaust note. ( Ok, ok, I’m a V8 junkie, no question about it. ) V8’s are most often found in trucks and muscle / sports cars. V8’s are not [...]

V6 - An engine with 6 cylinders, arranged in 2 banks of 3, forming a V shape.
The V6 engine is right up there with the I4 in terms of popularity. Everything from the Nissan Altima to the Lexus IS250 use a V6 engine. Hugely popular, and offers the best of both worlds, with regards to [...]

I8 - Inline 8 cylinder engine: An engine with 8 cylinders, arranged in a single row. No automaker currently uses this design due to packaging issues. To fit an I-8 under the hood, a car needs a simply massive hood, and the V8 is a much more compact, smarter choice. I8’s haven’t been seen in [...]

I6 - Inline 6 cylinder engine: An engine with 6 cylinders, arranged in a single row. Automakers are starting to move away from the I6 in favor of the V6, which is a more popular design currently. The now-retired Toyota Supra made good use of the I6 engine. Currently BMW is the king of the [...]

OHV- Overhead Valve: The OHV engine is often called a pushrod. The name stems from the design, of course. An OHV engine has the camshaft located on the cylinder block itself, instead of on the cylinder head like a SOHC or DOHC design. The camshaft is attached to pushrods ( hence the [...]

DOHC - Dual overhead Cam: Two camshafts per bank of cylinders, located on the cylinder head. Example: A DOHC I4 would have 2 cams, while a DOHC V8 would have 4 cams. Again, just like the SOHC design, it’s important to remember that with a DOHC setup, there are two cams per [...]

SOHC - Single overhead Cam: One camshaft per bank of cylinders, located on the cylinder head. Example: A DOHC I4 would have 1 cams, while a DOHC V8 would have 2 cams. Many people forget that it’s one cam per bank of cylinders - that’s very important. The majority of SOHC engines [...]

CVT - Continuously variable transmission: An automatic transmission with a nearly infinite number of gear ratios. In general, the more gears a transmission has, the better it can use it’s available power, and the better the fuel economy. With a nearly infinite number of gear ratios, the CVT delivers the best of both [...]
