LeftLaneNews Details GM’s LS Engine Plans

by Keith Cornett on October 31, 2007

Leftlanenews.com did a query of their sources at GM to provide a detailed look of future plans for GM’s LS engines. For our purposes, we’ll cover the three that have implications for Corvette: The LS7, LS8 and LS9. The LS7
The LS7 is a naturally aspirated 7.0 liter motor and is the current top of the line performance engine for GM, appearing exclusively in the Corvette Z06. It is hand built at GM’s Wixom Performance Center, and therefore very expensive to make. The LS7′s days are numbered according to Leftlanenews sources, ceasing production sometime during late 2009 or mid-2010. Previous rumors of the Cadillac CTS-V getting the LS7 appear to be false. Instead, the performance Cadillac sedan will get the new LSA motor next year with the Corvette Z06 upgrading to the supercharged small block LS8 in 2010. The LS8
The LS8 is a 6.2 liter smallblock V8 with a supercharger. This motor will be dropped into the top-end Zeta platform cars with the Camaro Z28 being the most likely candidate. Initial specs have it at 475-500 horsepower with a choice of manual or automatic transmissions. As mentioned above, the Corvette Z06 will receive this power plant in 2010 with a possibility of an uptuned version to ensure Corvette’s horsepower superiority over the Zeta cars. The last thing a Corvette owner who plunks down $75K for a Z06 is going to want to hear is that they bought the Corvette with the Camaro engine. The LS9
So much has already been written about the LS9 that is seems like it’s already in production and out on the streets. Another 6.2 liter smallblock V8 with a supercharger, it has an integrated intercooler on the intake manifold. Estimated horsepower is speculated to be 650 hp with 700 hp in reach. The ZR-1 may also feature an optional automatic with paddle shifters. Earlier this year it was said that the LS9 would come only equipped as an automatic, but the run by the ZR-1 with an LS9 coupled to a 6-speed manual transmission at Laguna Seca earlier this month quashed that rumor. The LS9 will be hand built starting in July 2008 at Wixom Performance Center alongside the LS7 as no more than 2,000 units are expected per year.
