Performance Axle Ration
I'm getting ready to order a 2008 Convertible with paddle shift and am
considering ordering the "2.73 Performance Rear Axle Ratio". Can anybody give me a description of what that is, and difference it makes in acceleration or speed? Is it worth $395? Thanks, Scott -- |

Generally, a lower gear ratio (3.55/1 being a lower gear ratio than 3.00/1) reflects a quicker launch, quicker run through each gear, and ultimately (theoretically) a lower top end speed. |

In a 2005 the rear gears from the factory a auto: 2.73:1 or 3.15:1;
manual: 3.42:1, limited slip. Would the be the same in a 2008? -- 1972 War Bonnet Yellow Corvette 1981 White Corvette 1995 Competition Yellow Corvette "Dale" > wrote in message ... > On or about Sat, 20 Oct 2007 07:01:34 -0700, "Big Al" > > wrote or did cause to be written: >> >>2.73 does not seem like a performance ratio.

I have a 2004 Auto with a 2.73 ratio.
The good news: 21 MPG around town, 25 highway. The bad news: Could be faster, IMHO. A 2.73 rear end ratio IS NOT a "performance" item. It gives you better MPG and slower 0-60.....0-100 on up times. Helps Chevy meet their CAFE numbers. The higher the number, the more "performance" from the rear axle ratio. 2.73.....bad. 3.48...good 4.11....better Gas mileage?? Who cares. That's not why I have it. It's a 'Vette not a Vega!
