In these times, where every engine in modern cars has overhead cams, why does Corvette still have push rods? This is a common question we get from new Corvette buyers. Is it because GM is slow to change, or is there a good logical reason?
When you look at the push rod design, you can instantly notice a few things. #1 the engine is not as tall as an over head cam engine. #2 the engine is shorter. #3 it is less complicated. It turns out a push rod engine, can also produce a lot of low-end torque, this is what makes a car accelerate, and is a good thing for sports cars. The downside is that the red line is lower.
Other advantages of a push rod engine is that they are simpler, less expensive to produce and sit lower in

There’s a lot of talk, and videos, popping up on the internet about the 2019 ZR1 these days. New owners are mounting cameras and taking them to Dynos, Race Tracks and Drag Strips and GM is testing at Nurburgring.
Since they were already in Germany, GM decided to make the 240-mile trek to ATP Automotive Testing Papenburg, one of the largest proving grounds in the world and one that has miles upon miles of straight track looped together with banked curves at the end.
To establish an official top speed, a vehicle must make two passes on the track, one in each direction to correct for the wind. The top speed is the average of the two speeds. The 2019 ZR1 hit 214.88 mph in one direction and 210.20 going the other way around, setting an official top speed of 212.20 mph!
Corvette Racing has been taking on all competitors in North America and around the globe for 20 years in a row and now has 107 victories worldwide – 99 in North America, 8 at the 24 Hours of Le Mans, 12 Manufacturer and Team Championships and 11 Driver Championships.
At Long Beach, CA., this last weekend, Corvette Racing proved they still have the touch this year. Gavin and Milner, who almost lost it in the last corner, won in their No. 4 C7.R for the second year in a row while Garcia and Magnussen struggled back from eighth place, due to a spinning out at a re-start, to finish in fourth place.
