Dexos1™ Engine Oil Specification — Recommended Viscosity

Only those oils displaying the dexos1™ trademark and a registered trademark logo on the front label of the container meet the demanding performance
requirements and stringent quality standards set forth in the dexos1™ specification.
Look on the front label for either of the logos shown above and the 11 digit alphanumeric dexos® license number on the back label to identify an authorized,
licensed dexos1™ engine oil. Unless an oil package displays these two markings, the engine oil is not an authentic, licensed dexos® product and is not
recommended for use in GM vehicles.
The dexos1™ specification was uniquely designed to complement the exacting requirements of GM's advanced engine technology. The specification has gone
through an extensive developmental and testing process. It requires a number of proprietary tests that are not included in current industry standards and sets
performance criteria at a level that exceeds many current standards. The result is a high performance fluid providing significant wear protection, improved
4

piston cleanliness, a reduction in volatility and oil consumption, enhanced aeration control for improved fuel efficiency, and better oxidation properties.

Viscosity Grade

Notice: DO NOT use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50.
–

Z51 Performance Package vehicles utilize the dry sump oil system. This vehicle will come with factory fill 5W-30 dexos1™ oil and an oil fill cap identifying
that 5W-30 dexos1™ oil is recommended to top off the engine or for an oil change.

–

SAE 5W-30 is the best viscosity grade for the vehicle.

–

For cold temperature operation, where the temperature is colder than −20°F (−29°C), SAE 0W-30 may be used.

–

For track events or competitive driving, Mobil 1™ 15W-50 engine oil must be used.

Refer to this General Motors website for dexos1™ information about the different licensed brands that are currently available: http://www.gmdexos.com

Powertrain / Drivetrain

Engine 6.2L RPO LT1
The 2014 Corvette Stingray is the most powerful standard model ever, with 455 horsepower (339 kW) and 460 lb.-ft. of torque (623 Nm). It can accelerate from
0-60 mph in less than 4 seconds and achieve more than 1 g in cornering grip. Vehicles equipped with the Performance Exhaust system RPO NPP, will generate
460 horsepower (343 kW) and 465 lb.-ft. of torque (630 Nm).
The engine offers advanced technologies that include Direct Injection (DI), Active Fuel Management™ (AFM), Continuously Variable Valve Timing and an
advanced combustion system that delivers more power while using less fuel.
The engine features a cast aluminum block, cast aluminum cylinder heads with two valves per cylinder and a compression ratio of 11.5:1.
The recommended fuel for this engine is premium unleaded gasoline with a posted octane rating of 91 or higher. Regular unleaded gasoline rated at 87
octane or higher can be used, but performance could be reduced, and an audible knocking noise may be heard. General Motors recommends using a TOP
TIER Detergent Gasoline. Go to this website: www.toptiergas.com for a list of TOP TIER Detergent Gasolines.

DEX-COOL® Engine Coolant/Antifreeze and Water Mixture Recommendation
The 2014 Stingray uses a new recommended engine coolant/antifreeze and water mixture of 40% DEX-COOL® antifreeze and 60% clean, drinkable water. A
40/60 mixture is 2:3 (2 parts antifreeze - 3 parts water).
–

In the United States use DEX-COOL Coolant GM P/N 12346290

–

In Canada use DEX-COOL Coolant GM P/N 10953464

Transmission
Launch Control and Performance Traction Management technologies are included with the automatic and manual transmissions. The following transmissions
are available:

•

A 6-Speed 6L80 Automatic Transmission with Paddle Shift — RPO MYC

5

•

A 7 Speed Tremec (TR6070) Manual Transmission with Active Rev Match (ARM) — RPO MEL or MEP

Automatic Transmission — Using Paddle Shift
The Manual Paddle Shift system can be used in D (Drive) or M (Manual Mode). The system is activated by pushing the left paddle to downshift and right paddle
to upshift. The current gear will be displayed in the instrument cluster, or the Head-Up Display (HUD), if equipped. The Manual Paddle Shift system will not allow
either an upshift or a downshift, if the vehicle speed is too fast or too slow, nor will it allow a start from 4 (Fourth) or higher gear.
While in M (Manual Mode), the paddles on the steering wheel can be used to manually upshift or downshift the transmission. The left paddle downshifts and
right paddle upshifts. When accelerating the vehicle from a stop in snowy and icy conditions, shifting to 2 (Second) or 3 (Third) gear allows the vehicle to gain
more traction. If traction control is active, upshifts are delayed to increase control of the vehicle.
The Manual Paddle Shift system can be deactivated by moving the shift lever from M (Manual Mode) back to D (Drive). While in D (Drive), tap either the
upshift or downshift controls to place the transmission in Manual Paddle Shift mode. To exit Manual Paddle Shift mode, hold the upshift control for more than one
second. The system will return to automatic shifting after 10 seconds of cruising at a steady speed and no manual shifts, or when the vehicle comes to a stop.
While the Manual Paddle Shift gear selection system is active, the transmission will automatically downshift through the gears as the vehicle slows. The
transmission will select 2 (Second) gear as the vehicle stops. From a stop, the vehicle will start from and hold 2 (Second) gear unless the manual paddle shifts
are used to shift into a different gear, or D (Drive) is selected. The driver can select 1 (First) gear for maximum acceleration from a stop.

Manual Transmission — Active Rev Match (ARM) — Hill Start Assist (HSA)
Vehicles equipped with the 7 Speed Tremec (TR6070) manual transmission have Active Rev Match (ARM). ARM aids in smoother shifting by matching the
engine speed (RPM) to the next selected gear. By monitoring shift lever and clutch operation, ARM adjusts engine speed to match a calibrated value. On
downshifts, engine speed will be increased before the clutch is engaged. On upshifts, engine speed is reduced to a calibrated value. Rev matching is
maintained for a few seconds between shifts, then deactivates if the shift is not completed, and engine speed returns to idle.

The ARM system is activated and deactivated by pressing either of the paddles marked REV MATCH on the left or right side of the steering wheel. The system
must be activated with each new ignition cycle.

Hill Start Assist (HSA)
Vehicles equipped with the 7 Speed Tremec (TR6070) manual transmission have a feature called Hill Start Assist (HSA). When stopped on a hill, HSA prevents
the vehicle from rolling before driving off, whether facing uphill or downhill by holding the brake pressure during the transition between when the driver releases
the brake pedal and starts to accelerate. HSA is only active for a few seconds but it will re-engage if the brake pedal is applied again. The electronic brake
control module (EBCM) calculates the brake pressure, which is needed to hold the vehicle on an incline or grade greater than 5 percent and locks that
pressure for up to 2 seconds. The stop lamps will stay illuminated during HSA operation even though the brake pedal is released, this is considered normal
operation.
HSA will not activate if the vehicle is in a drive gear and facing downhill or is in R (Reverse) and facing up hill.

Transportation Cover
All Corvette Stingrays are shipped with a transportation cover. The cover should remain on the car during storage at the dealership to keep it protected from
environmental fallout. The cover should be removed when the car is delivered to the customer. Once the cover is removed it should be provided to the
customer if they want the cover. It can be rolled or folded and placed in the rear of the car. The cover can be washed and reused if the customer so desires. If
the customer does not want the transportation cover it can be discarded.

Transport Mode
The Corvette MAY be shipped in transport mode. To remove the car from transport mode, turn ON the four way flasher and place the driver’s foot on the brake

6

AND on the clutch if it is a manual transmission. Press and hold the Start button for approximately 15 seconds. At this point the engine will START, but
CONTINUE to hold the start button for approximately 15 seconds. Information will display on the center of the cluster that will indicate when transport mode has
been turned OFF. Transport mode can be entered using the same procedure.

Z51 Performance Package
The Z51 Performance Package will be offered as the top performance Stingray. This package includes larger forged aluminum 19-inch front and 20-inch rear
wheels, dry sump oil system, Electronic Limited Slip Differential (ELSD), larger front brakes (13.6-inch vs. 12.6-inch) with black calipers, specific shocks,
springs and front stabilizer bars, differential and transmission cooling, as well as a unique Aero Package that reduces lift for high-speed stability. Magnetic
Selective Ride Control and Performance Traction Management are available.
The Michelin® Pilot Super Sport® ZP summer-only tires on the Z51 Performance Package are unique and aggressively tuned to provide outstanding handling,
grip and road-holding capability.

Z51 Performance Package Front Tire Chatter/Noise
The Michelin® tires may exhibit a chatter noise during low speed tight turn conditions (i.e. parking lot, driveway, etc.) when the tires are cool. The condition can
be experienced in all directions: right, left, forward, reverse. The condition typically reduces or diminishes when the tires warms up, but may become worse
when the pavement is wet. For these unique and aggressively tuned high performance tires, this is considered a normal condition. For more information, refer
to the latest version of Corporate Bulletin Number #09-04-20-001: Front Tire Chatter/Noise vs. Rear Differential Chatter

Checking Engine Oil / Dry Sump Oil Tank Noise on Startup
The Z51 Performance Package has a high performance dry sump lubrication system. This system operates differently than a standard engine lubrication
system. Check the oil level only after the engine has been thoroughly warmed up and then check after a minimum of 5 minutes but no more than 15 minutes of
engine shutoff. This ensures that the oil level reading obtained will be accurate.
Some customers may comment on a noise similar to running water that can be heard from the dry sump oil tank area when the engine is cold and started. This
is a normal sound caused by the oil returning to the tank.

Engine Oil and Oil Filter Replacement (With Z51 Performance Package)
Caution: This engine uses a special high performance oil filter. Use of any other filter may lead to filter failure and/or severe engine damage. Use
oil filter PF64, General Motors P/N 12640445 or equivalent.
Notice: Z51 Performance Package vehicles utilize the dry sump oil system. This vehicle will come equipped with factory fill 5W-30 dexos1™ oil
and an oil fill cap identifying that 5W-30 dexos1™ oil is recommended to top off the engine or for an oil change.
To properly change the engine oil and oil filter, refer to Engine Oil and Oil Filter Replacement (With Z51 Performance Package) in SI

Hydroformed Aluminum Frame

The 2014 Corvette Stingray utilizes an all-new aluminum frame structure that's lighter and stronger than the previous steel frame. The new aluminum frame
structure is 57 percent stiffer and 99 pounds (45 kg) lighter than the steel frame used on the previous generation.
Compared to the previous generation, which used continuous hydroformed main frame rails with a constant 2 mm wall thickness, the new frame features main
rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the
suspension interface points. Each segment is tuned – varying in thickness from 2 mm to 11 mm – tailoring the gauge, shape and strength properties to optimize
the requirements for each frame section with minimal weight.
The frame is assembled at an all-new welding shop at the Bowling Green Assembly Plant using a unique laser welding process in which a computer-controlled

7

beam of high energy joins the components with exceptional precision and tolerances of about 0.001-inch.
Supporting the frame’s greater strength and lower weight are complementing chassis elements, including hollow-cast aluminum front and rear cradles that are
approximately 25 percent lighter and 20 percent stiffer than the solid cradles used on the previous structure.

Battery in Rear Compartment / SPID Label
Notice: Be careful when pulling up the carpet or damage to the carpet can result.
The battery is located in the rear compartment of all Corvettes for 2014. To access the battery the carpet must first be untucked from the rear and right side
trim panels and then lifted. If just the right rear corner is lifted it will tear the carpet backing and the carpet will not lay flat.
The SPID label is located on the cover next to the battery.

Brakes / Electric Parking Brake (EPB)

Standard Brembo brakes, with four-piston fixed calipers derived from racing, deliver exceptional stopping power on the street or track. System highlights
include:

•

12.6 inch (320 mm) front rotors and 13.3 inch (338 mm) rear rotors are standard and have 35 percent more swept area than previous-generation brakes.
This feature improves stopping distance by 9 percent.

•

Dual-cast, slotted 13.6 inch (345 mm) front rotors and 13.3 inch (338 mm) slotted rear rotors are included with the Z51 Performance Package. They have
6 percent more swept area than the previous-generation Grand Sport and are cooled front and rear for improved track capability. This feature improves
stopping distance by 5 percent.

•

All brake packages have four-piston fixed front and rear calipers for more even pad wear, reduced drag and improved modulation.

The front rotor on the Z51 Performance Package uses a two piece cast rotor. By design there is some slight clicking or slight rattle noise that may be heard
when the brakes are applied.
The brakes on all vehicles use an aggressive pad material for enhanced braking capability. It is common for the brakes to create brake dust and some slight
noise is also considered normal. Pads or rotors should not be changed in an attempt to correct brake dust or noise.

Electric Parking Brake (EPB)

8

The Corvette does away with the mechanical lever-based parking brake system in favor of an electric parking brake (EPB) controlled by a push-button (1) that
is mounted on the center console. This feature saves space in the cabin. The EPB can always be activated, even if the ignition is turned OFF. To prevent
draining the battery, avoid repeated cycles of the EPB when the engine is not running. In case of insufficient electrical power due to a discharged or dead 12V
