C7

After several hours, we swapped cars to acquaint ourselves with the Chevrolet and it was instantly disappointing. The heavy twin-plate clutch accessed a notchy gearbox, the numb steering was slow, throttle actuation ponderous and the body rolled into turns, giving an impression of considerable weight. It felt industrial, almost agricultural. Even the exhaust note was muted and monotone.

All this shone an even brighter light on the Jaguar, but the Stingray hadn’t warmed to us yet. It took a few miles before we could appreciate what it had to offer.

Let’s start with the transmission because it dominates first impressions. Being a seven-speed takes some familiarization, since the neutral position is sprung between third and fourth. This means that higher ratios require the lever to be pushed to the right, but finding the right amount of pressure took a few miles. And although we didn’t like the idea of a gear indicator, it proved useful at first when confirming you guessed right.

Another unwanted aid was the Rev Matching function. It was selected by the redundant shift paddles left over from the automatic transmission that’s also available with this car. Once armed, down changes were accompanied by a throttle blip to ensure smooth engagement. However, it also has the effect of making every Corvette owner sound like a racecar driver.

Along with its Hill Hold function and electronic parking brake, the Stingray usurps the art of the heel-n-toe downshift or the e-brake hill start, allowing the electronics to empower the incompetent. Frankly, if you can start a manual car on a steep hill or rev-match on downchanges without these devices, we’d question why you’re at the wheel of a 460hp Corvette!

That said, it makes the car accessible to more people, and at least Chevrolet has provided a manual option. Kudos to an American manufacturer for not abandoning the clutch pedal entirely. In fact, European Corvette owners won’t even get the automatic option.

While transmissions such as the eight-speed auto in the Jag are exemplary, there are still some of us who enjoy the control and flexibility of selecting our own gears and side-stepping the clutch occasionally.

There were voices who suggested we shouldn’t compare the manual Vette to the auto F-Type, but we felt we should test the best of what’s available. And because the C7 even has a manual option, it will be a better choice for drivers like us…

The Vette was fitted with the optional Magnetic Ride Control, which damped uneven road surfaces slightly better than the Jag. It allowed a curious amount of body roll, but that allowed you to setup the car for each turn, shifting the weight with the steering. At low speed the car felt heavy, but the responses lightened as speed increased. So at very high speed, the Stingray felt more stable than the Jaguar, with its Michelins and transparent traction control keeping the Vette pointing in the right direction at all times.

In fact, all our complaints evaporated once we settled into the car. The steering became more positive at speed, and the four-piston Brembos were easier to modulate than the Jag’s brakes, giving you a little more confidence into turns. The grip on exit was astonishing, making it feel as if every turn could have been taken faster if you had another go.

The exhaust note also improved. Although it maintained the same hollow bellow at all engine speeds, it happily gained volume and purpose with velocity. It made the car feel more brutal, more substantial than before.

The Performance Exhaust fitted to our car gave an extra 5hp and 5 lb-ft, but that was icing on an already well-decorated cake. It’s amazing to think that in 2013, Chevrolet’s flagship model uses a two-valve pushrod engine, but this 6.2L LT1 V8 generates 50 lb-ft more torque than the outgoing 7.0L LS7 in the 2013 Z06. It also offers a better power to weight ratio than the 911 Carrera or Audi R8, making it a serious contender at a fraction of the price.

In Z51 guise, it gets dry-sump lubrication and better cooling, making it ideal for track use.

The Corvette has a sensitive side, though. Its Drive Mode selector allows you to access Eco, Weather, Tour, Sport or Track settings. These are fairly self-explanatory, with Eco mode allowing the engine to operate as a V4, deactivating half the cylinders to make its 29mpg EPA rating possible. Meanwhile, the F-Type gets stop/start technology to also reduce fuel consumption.

Of the other modes, Weather was designed for rain or snow, while Tour was designed for daily driving. Admittedly, we spent most of our time in Sport, giving us access to different settings on the throttle, steering, suspension, e-diff, traction control and exhaust flaps.

In Sport, we found that throttle sensitivity had an interesting step, where it allowed you to potter around at regular speed without drama. But push past some resistance and the car introduced a different side to its character at full throttle. It awoke with a start, careening forward with a velocity and noise previously unknown. That’s when you realized it was genuinely 0.4sec quicker to 60mph than the Jag, and would probably keep accelerating past it in the higher gears.

We should point out that seventh gear on the manual is strictly for cruising. You’ll need to change down to pass anything since it’s loping along at 70mph at about 1400rpm. It’s strictly for fuel saving and worked well in combination with Eco mode, where we saw some savings.

That said, we returned about 19mpg average in the Corvette, where the Jaguar saw 20/21mpg. This defied the stats because we spent hours on the freeway, but the 6.2L Vette required engine revs to gain speed, where the Jag had more to offer at lower RPM. This seemed to give the F-Type a narrow advantage at the pumps during our 500-mile adventure. Daily driven in Eco mode, we’re confident that the Corvette’s cylinder deactivation should be able to do much better than we managed…

At the end of the day, the Vette needs to be manhandled to extract its best. Where the Jag is instantly accessible, the Chevy seems to have a secret level, only accessed once you have the password. Yet the harder you push, the better the C7 feels. This is possibly because its roots are more muscle car than sports car, lacking the grace and agility of the F-Type. It certainly couldn’t be called subtle!
