And just as it\u2019s done with the TRX\u2014and many other trucks, SUVs, and muscle cars\u2014Hennessey Performance Engineering has given the RHO an upgrade.<\/p>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">The Hennessey Mammoth 700 treatment gives the <a href=\"https:\/\/www.autoblog.com\/reviews\/i-test-drove-the-2025-ram-1500-rho\">Ram 1500 RHO<\/a> more power, bigger tires, and a bit more attitude. And while Hennessey didn\u2019t disclose a price for the upgrades, which customers will have to pay on top of the roughly $70,000 cost of an RHO donor vehicle, keep in mind that the final versions of the TRX cost around $120,000 when new.<\/p>\n<p><!-- --><br \/>\n<!-- --><br \/>\n<!-- --><br \/>\n<!-- --><\/p>\n<h2 class=\"wp-block-heading\" id=\"trx-challenger\">TRX Challenger<\/h2>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">The RHO serves as showcase for the Hurricane twin-turbocharged 3.0-liter inline-six that replaced V8 engines in the <a href=\"https:\/\/www.autoblog.com\/tag\/ram\">Ram<\/a> lineup for the 2025 model year. The RHO\u2019s \u201cHigh Output\u201d version makes 540 horsepower, but Hennessey pushes output to 700 hp with increased boost pressure, new engine management software, and a new stainless steel exhaust system. That\u2019s in line with the 702-hp TRX.<\/p>\n<p><!-- --><br \/>\n<!-- --><br \/>\n<!-- --><\/p>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">The Mammoth 700 is also available with an off-road package that includes a 2-inch suspension lift, leveling kit, and 37-inch tires mounted on 20-inch wheels. Keep in mind that the stock RHO, which rides on 35-inch tires, already had a 2-inch lift affording 11.8 inches of ground clearance.<\/p>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">Visual changes include a new front bumper with integrated LED light bar, a new rear bumper, and the requisite Hennessey badging. Hennessey also includes a skid plate, and performance <a href=\"https:\/\/www.autoblog.com\/features\/best-brake-pads\" rel=\"noopener\" target=\"_blank\">brake pads<\/a> and rotors to deal with the truck\u2019s increased power.<\/p>\n<p><!-- --><br \/>\n<!-- --><br \/>\n<!-- --><\/p>\n<h2 class=\"wp-block-heading\" id=\"stopgap-effort\">Stopgap Effort?<\/h2>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">Whether in stock form or modified by Hennessey, the RHO is a very capable truck. But just as <a href=\"https:\/\/www.autoblog.com\/ford\/\" rel=\"noopener\" target=\"_blank\">Ford<\/a> eventually caved to pressure and introduced the Raptor R alongside the standard V6 version, a new factory V8 performance truck from Ram seems inevitable. Stellantis CEO Antonio Filosa said as much during the automaker\u2019s last earnings call, noting that <a href=\"https:\/\/www.autoblog.com\/news\/confirmed-the-hellcat-powered-ram-trx-will-rise-again\">a revived TRX<\/a> and other V8 trucks would help increase sales volumes.<\/p>\n<p><!-- --><br \/>\n<!-- --><br \/>\n<!-- --><\/p>\n<p data-wp-block=\"{&quot;dropCap&quot;:false}\" data-wp-block-name=\"core\/paragraph\">That V8 revival has already started with the naturally-aspirated 5.7-liter Hemi, which returns to the Ram 1500 <a href=\"https:\/\/www.autoblog.com\/news\/rams-hemi-v8-comeback-triggers-ordering-frenzy\">for the 2026 model year<\/a>. A new TRX doesn\u2019t seem far behind, part of a wave of new products from the truck brand that will also include <a href=\"https:\/\/www.autoblog.com\/news\/rams-new-midsize-truck-is-coming-for-the-toyota-tacoma\">a midsize pickup<\/a>, and possibly <a href=\"https:\/\/www.autoblog.com\/news\/ram-to-challenge-ford-and-mercedes-with-unexpected-vehicle-return\">a passenger van<\/a>.
