The Chevrolet Impala PPV (police patrol vehicle) receives a performance upgrade for 2012, with a new, more-powerful 3.6L V-6, six-speed automatic transmission and 17-inch wheels. StabiliTrak stability control is new for 2012 and includes performance mode and traction control.

The 3.6L “LFX” engine is rated at 302 horsepower (225 kW) – a 31-percent increase over the previous 3.9L V-6. Its features include direct injection, continuously variable valve timing and E85 capability. Although the new engine packs more than 70 more horsepower, its efficiency-enhancing features and its pairing with the fuel-saving six-speed automatic mean it retains good fuel economy.

For 2012, the Impala PPV is available in police patrol or undercover police packages, offering large-car utility with midsize agility, along with power, roominess and style.  Police-specific equipment includes speed-rated tires; battery run-down protection; plug and play electrical wiring harnesses; and lockout protection, which prevents the power door locks from locking the driver's door when the keys are in the ignition.

Impala Police performance

The new LFX3.6L V-6 becomes the standard engine in the 2012 Impala Police, replacing the previous 3.9L engine and delivering 31-percent more horsepower.

The 302-horsepower (225 kW) LFX is a 60-degree design, with the cylinder block and cylinder heads cast in aluminum for low weight. A forged steel crankshaft provides optimal strength in the bottom end, while the cylinder heads include four valves per cylinder, with a dual overhead camshaft design incorporating infinitely variable cam phasing.

Additionally, optimized-flow fuel injectors and the integrated exhaust manifolds/cylinder heads promote lower emissions. The LFX’s composite intake manifold also has a comparatively small radiated surface area to help it maintain excellent noise and vibration characteristics that are comparable to an aluminum manifold.

The 3.6L engine is backed by a new six-speed automatic transmission that is performance-calibrated for police duty.

Additional powertrain and vehicle system features include:

  • 2.44 axle ratio.
  • 170-amp high-output alternator.
  • Engine oil, transmission and power steering coolers.
  • Seventeen-inch wheels replace the 2011 models’ 16-inch wheels.
  • Goodyear P235/55R17 W rated tires

Optimal vehicle handling is assured by Impala's four-wheel independent suspension. It features reinforced front struts, a reinforced aluminum engine cradle and heavy-duty front and rear stabilizer bars. The Impala Police car is equipped with anti-lock disc brakes with police calibration and heavy-duty front brake pads.

StabiliTrak electronic stability control is new for 2012 and includes performance mode and traction control.
