Chevrolet chose not to include fuel-saving stop-start technology in the 2014 Corvette Stingray package, but future Corvettes may get it as government-mandated fuel economy requirements are raised. To explain why the launch-year model doesn't have the technology, Corvette chief engineer Tadge Juechter simply says, "It is more mass and more cost," Edmunds reports. As sports car enthusiasts, we like the sound of that.

Juechter has them at heart as he relates why stop-start systems aren't valued by Corvette customers: the "real environmental value is zero," he says, and it is perplexing why the "great-sounding engine" should be shut off at every stop. He's got a point, but the reality is that engines use fuel and create smog at idle. "Customers will have to put up with changes from what they traditionally expected in order to get better fuel economy," Juechter says.

Despite eschewing stop-start, the new Corvette's fuel economy reportedly increased by almost 12 percent over the 2013 model. A Stingray equipped with the seven-speed manual transmission is rated at 17 miles per gallon city and 29 highway, which are very good numbers for a sports car with a 6.2-liter V8 and 455 horsepower.

      Stop Start is an answer to a question never asked. It should be left out of performance cars. However if its necessary, engineers should allow the owner to disable it at their own choosing.

        right now the EPA does not use start stop to test for mog, so they turn it off, therefore gm has no reason not to have the system be at the drivers control.... in the 3er once you turn off of it will only come back on if you turn it on.... and I think GM will use a version that's not as noticable as that on the bmw

      Not a big fan of start/stop tech, and especially not on something like the Vette. I know the systems will get better as time goes on, but from what I've experienced in a BMW...it isn't quite seamless. Not to mention the extra wear and tear on the starter mechanism..

        That is why it is a bad idea to do start-stop with the starter and ring gear. I believe GM used a belt to do start-stop on a mild hubrid pickup truck a few years ago. That is the right approach. Replacing a belt is a whole lot cheaper than replacing a starter/ring gear.

      I think that anything that improves mileage is great but in a car like the corvette it should be optionally disabled. But what i really want in a car is a start-stop that i can control. Give me a car with a manual transmission and when i put the shifter in neutral and let the clutch out, i want the ending to stop. This way i can control when the engine stops. If my accessories are made to work with the engine off as many cars are now, then i can hypermile my car in an entertaining way saving gas. But if i dont want to i dont have to. But the important thing about this is i control it, and getting good mileage takes skill with a manual and thus it has some entertainment value. Aside from the hydraulic brakes, most cars have accessories set up to handle this.

      Just dont do it the way BMW does it- by using the regular starter and flywheel. This is a very stupid idea. BMW even warns you in the owners manual that using the start-stop will shorten the lifespan of certain components.

        What this guy said. Every time I drive a new 328i (my 335i is constantly in the shop) with start/stop, I marvel at how such a poorly executed feature made it onto a $50,000 car with a turbo-four in it. The shutter this thing sends through the car, the drivers seat, and the steering column is simply egregious in a car costing so much from a brand that's known for refinement and engineering scruples. I'm completely for start/stop tech. However, it needs to be implemented in a way that is seemless, well-engineered, reliable and refined.

      This car is nothing to be impressed with. I've heard of a 2.0L turbo with 350/350HP/TQ that gets 30mpg while turning 3500rpm, doesnt need a downshift from top gear to pass anything on the road and instead of harmful exhaust coming out of the tailpipe it emits the breath of god himself.

      Start-stop doesn't save all that much fuel. Besides, I echo other sentiments that if you have a roaring V8, it just confuses people if it turns off. Let's let the Corvette be a Corvette.

          5 mpg seems more than a little optimistic, but I would expect some significant savings when dealing with such a large engine.

          • 1 Year Ago
          Knowing Laser, he probably sits at stoplights and revs the engine. In that case it might make 5 mpg of difference. ;-)

          • 1 Year Ago
          Jeez, a little harsh right? Usually companies "claim" it'll save around 5-10%. Seeing as how their studies would be tailored toward a positive perception of the tech, it's probably only for cars that spend the vast majority of their time at traffic lights. I don't know if they've released official numbers for the C7, but this means 1.5-3 mpg improvement AT CONSTANT TRAFFIC LIGHTS... so no, not really that effective especially when sacrificing the beautiful V8 sound.

          • 1 Year Ago
          And furthermore, there's no way you're getting 42 unless you average 60 mph mostly highway... or you're driving a prius or diesel or something. Shutting off the engine at the occasional traffic light will not give you 5 mpg... liar.

      Reminds me of Top Gear's complaint about stop-start on the Porsche Panamera Turbo - "It's like buying a mansion the size of Buckingham Palace, and then living in one room so you don't wear the carpets out."

          You missed the point. Not about emissions, about fuel savings. You buy a very expensive car like the Panamera Turbo (MSRP $141k), gas savings is negligible by comparison. But even if you talk about emissions, trying to significantly offset the emissions of a 520 hp car by having start stop is pretty futile. Either way, regardless of talking fuel or emissions, if you're buying a 520 hp, $141k Porsche Panamera, shutting off the engine when you stop won't improve much. You'd be much better off getting a Tesla Model S.

        Those that produce and present Top Gear don't always quite live in reality. Road tax here is usually based upon CO2 emissions. In Europe, the stop-start helps cut the official CO2 figures, which then means cheaper levels road tax. When you buy the car, you can usually just switch it off by the in car settings and never bother with it. I don't really understand why people are so fussed by it. The technology itself doesn't add enough weight to the vehicle for people to be concerned about.

        I don't consider buffoonery entertaining. I would describe them as soft, alcoholic old salemen with no responsibility seeking to tap the the market made up of malcontent losers with appendage malfunctions. Their target demographic is the men and boys age fourteen and older with a mental age of 14, or basically boys who never grow up.

      I'm all for simplicity and would prefer my sports car to be just that. But with that said, I'll admit that my own car with stop-start is totally seamless and unobtrusive. It doesn't bother me a bit, and the silence at stoplights is kind of nice. So while my preference would be that the Corvette engine just keep running, I don't see this as a huge sacrifice.
