to police departments. The CL series also saw the arrival of the panel van variant to compete with similar offerings from rival makers. Interiors carried over largely unchanged from the VK range, though the Regal SE offered luxurious buttoned-leather seating as an option. Base Valiants continued with the previous Ranger style strip speedometer, while the Regal dash featured recessed circular gauges and clock with a woodgrain finish. The Charger 770 dash was similar to that of the Regal, except it was finished in black and had a tachometer instead of a clock. The Hemi-6 and V8 were dropped, and the only engine options were low- and high-compression versions of the Hemi-6 and the V8. The CL's introduction had closely coincided with that of the strict exhaust emission regulations contained in ADR 27A. With the 318 engine, a new emissions control system was introduced: Electronic Lean Burn. Transmission options were 3-speed manual with floor or column shift, four-speed manual with floor shift, and three-speed Torqueflite automatic with floor or column shift. The automatic was standard equipment with the 318 V8, and optional with a 6-cylinder. The 4-speed was optional for six- and eight-cylinder models. The floor-shift auto option was fitted to most Regals and all Regal SE's. In 1978 Chrysler released a limited edition run of 400 special Regal Le Baron models (option A17). The Le Baron was available only in Silver, with red or blue interiors. The 265 Hemi-6 was standard, and the 318 V8 was optional. Valiant and Regal sedans also benefited from the 1978 introduction of Radial Tuned Suspension in response to Holden's having marketed their suspension as particularly suited to radial tyres. RTS improved the car's handling and roadholding significantly, and "Modern Motor" magazine proclaimed that the Valiant offered a better drive than the Holden. The last special option in the CL range was the $816 Drifter''' package, available on the Charger. The Drifter package included Impact Orange, Sundance Yellow, Spinnaker White or Harvest Gold body paint, and large side and rear stripes. Drifters in white had additional "strobe stripes" on the bootlid. Engine options were again the 265 six or 318 V8, but the 4-speed manual was the only transmission option. A Drifter Pack was also offered on the Valiant Panel Van and on the Utility.Drifter Pack options Retrieved on 16 August 2010 36,672 CL Valiants – including the last-ever Chargers – were built. The CL
