in 2WD and 4WD drivetrains with orders coming in the first quarter of 2014 for special service models, followed by the orders for the police pursuit models afterwards. 2021 PPV The 2021 Tahoe PPV marks the most drastic change from the standard Tahoe. Rocker covers are borrowed from the GM LT4 engine found in high performance Corvettes, Camaros and Cadillacs. Engine and transmission coolers are PPV specific. Bridgestone co-developed Firehawk Pursuit tires with GM for the 20 inch steel wheels. 6 piston,16 inch rotor Brembo brakes are standard issue on the PPV. The suspension is lowered and further fortified. All wheel drive is standard and sent to the front as needed with a limited slip clutch in the transfer case. 160 MPH speedometer is standard and alternator almost doubles the amperage of the standard Tahoe. This version of the PPV uses the 9C1 code instead of the Z56 code. Military applications When production of the CUCV II ended in 2000, GM redesigned it to coincide with civilian truck offerings. The CUCV nomenclature was changed to Light Service Support Vehicle in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by 5.3 for the Tahoe, 6.0 for the Suburban, and a Duramax 6.6 liter turbo diesel engine for The pickup trucks. As GM has periodically redesigned its civilian trucks and SUVs from 2001 to the present, LSSVs have also been updated cosmetically. The militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook, tow shackles and a 24/12 volt electrical system. The dashboard has additional controls and dataplates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories. In the Canadian Army these vehicles are nicknamed "Milverado". The Enhanced Mobility Package (EMP) option adds an uprated suspension, 4-wheel anti-lock brakes, a locking rear differential, beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units have been sold to U.S. and international military and law enforcement organizations. Variants Cargo/Troop Carrier Pickup (2-door, Extended Cab, or 4-door Silverado)
