2011 Dodge Challenger: the 392 returns

This record's own dek describes 2011 as the year the 392 returns: a 470-hp 6.4-liter SRT8, 1,492 numbered Inaugural Editions, and a Pentastar V-6 for the SE. This record's own overview states that the SRT8 moved from the 6.1-liter HEMI to the 392-cubic-inch (6.4-liter) HEMI rated at 470 hp and 470 lb-ft, with the Tremec six-speed manual standard and a five-speed AutoStick optional, Brampton production dated to December 2010, while the SE switched to the 3.6-liter Pentastar V-6 at 305 hp and 268 lb-ft.^1,2

Dodge marked the 392's return with the SRT8 392 Inaugural Edition, offered in Deep Water Blue with Stone White stripes or Bright White with Viper Blue stripes, Pearl White leather, and a serialized plaque numbered from 1 to 1,492; Dodge states that 1,492 were produced, 1,100 for the United States and 392 for Canada, a split this record's own production section reproduces as its own two rows. Green With Envy, a limited-production color for the R/T Classic and SRT8 392, followed at the February 2011 Chicago show.^1,3

This record's own overview states that no total model-year production was found, with Chrysler's reported 39,534 calendar-year 2011 US Challenger sales reused as the best available substitute. This record's own production section also documents color-specific worldwide counts: 1,532 Green With Envy cars and 4,683 Toxic Orange cars, alongside two disputed Inaugural Edition color counts, 863 Deep Water Blue and 731 Bright White, which together exceed the announced 1,492 by roughly a hundred cars, a gap this record's own note says neither Dodge document explains.^4,5

Four engines are documented: the 3.6-liter Pentastar V-6 at 305 hp standard on the SE, the 5.7-liter HEMI V-8 at 372 hp with the automatic, the same 5.7 at 375 or 376 hp with the six-speed manual depending on the document, and the 6.4-liter (392) SRT HEMI V-8 at 470 hp and 470 lb-ft standard on the SRT8 392. This record's own conflicts section carries both the R/T manual horsepower split and a separate dispute over the 392's torque-peak rpm, 2,900 rpm in the Inaugural release against 4,200 rpm in the specification sheet, with the treatment noting that the release's 2,900 rpm was actually the point where Dodge compared the 392 against the outgoing 6.1, not its rated torque peak. Two transmissions are documented, the TR-6060 six-speed manual and the five-speed automatic with AutoStick.^6,7

This record documents an extensive options list, including the Inaugural Edition package itself with its own 1,492-unit installation count, the SE Rallye and R/T Plus and R/T Classic packages, a Rallye Appearance Group, a Super Sport Group, a Super Track Pak Group, and Mopar Exterior and Interior Appearance Groups. Ten exterior colors are documented, four of them carrying the production counts noted above, alongside five interior trim descriptions and a specifications section carrying SRT8 392 EPA fuel economy of 14/22 mpg automatic and 14/23 mpg manual, a 10.9:1 compression ratio, and rear axle ratios split by trim and package.^8,9

This record's own performance section carries three manufacturer claims for the SRT8 392, a top speed over 180 mph with the manual against 173 mph with the automatic, and a 0.90g skidpad, and its identification section documents VIN codes for the model, engine and assembly plant alongside the Inaugural Edition's serialized dash plaque. Its conflicts section logs three disputes in total: the R/T manual horsepower split, the Inaugural Edition production count against the two color-specific tallies that exceed it, and the 392's torque-peak rpm reading.^1,10
