    A LS7 is 32kg lighter than a M5 V10, and produces more peak power, alot more torque, with a usable torque band. Not to mention it costs a shit load less to build.

    That doesn't make the engine in the M5 any less impressive though :o

    Until the CTS-V comes out we won't know if GM can pull off putting that engine into a sedan.

    Simple large engine that makes gobs of usable power anywhere in the powerband > complicated engine that is heavier, has peakier powerband, and a lot less torque. Not to mention, the more complicated an engine is, the more expensive it is to fix and more likely things will break. The LS7 will also get better gas mileage and sound better.

    oh, i didn't realise that an LS7 and an M5 engine were the same size:hsugh:

    if the m5 engine was 7 liters it would be making 700hp :bowdown:

    I am wondering how GM will improve on its current crop of v8 engines. The LS1 wasn't a great engine, it lacked low down torque but was still a good v8, but the LS2/7 are superb.

    weight is a lot more important than displacement :gtfo:

    Is that ricer capacity talk? They are the same power, only the bigger LS7 weighs less and uses less fuel.

    The LS1 makes plenty of torque down low. It just has a smoother powerband than say an LT1. That is why the LT1 will feel faster down low, but it really isn't. I know that from experience :)

    The LS1 i owned, didn't really feel fast until 3500 revs, when it was in its power band, most large 6 cylinder engines had more sub 3k rpm pull.

    if means shit really. BMW chooses the route of more complicated and heavier engines to make power. While their engines are impressive, they are too complex for their own good and they lack torque compared to a smaller and lighter pushrod engine.

    no, just saying it's not fair to compare the two

    Don't get me wrong. The LS1 definitely is a great engine higher up in the powerband where the LT1 would fall on its face. However, an LS1 can stay with the LT1 down low with no problems.

    it is when the ls7 gets better efficiency numbers and weighs less.

    When will people learn capacity is practically irrelevant. The only reasons to not use a higher capacity engine is fuel consumption and engine weight/size, if that can be overcome, higher capacity engines offer more power and flexibility.
