Editing GMC Syclone (section)

==Production run==
The GMC Syclone, Typhoon, and Sonoma GT were built by GMC and PAS ([[Production Automotive Services]]) of [[Troy, Michigan]], and sold through dealerships. At the time it was introduced, the Syclone was the fastest stock pickup truck being produced in the world. Auto magazines compared its acceleration favorably to a variety of sports cars including the [[Chevrolet Corvette (C4)|Chevrolet Corvette]] and—in a memorable comparison test in [[Car and Driver magazine|''Car and Driver'' magazine]]—a [[Ferrari 348|Ferrari 348 ts]].<ref>{{cite web | url=http://www.sportmachines.com/wiki/tiki-index.php?page=Car+and+Driver+Sept+1991&bl=y| title=Car and Driver Sept 1991| work=sportmachines.com}}</ref> The Syclone features a 4.3L turbocharged V6 engine with an automatic transmission and an AWD (all-wheel drive) driveline and 4-wheel anti-lock brakes.

Both the Syclone and Typhoon trucks feature a [[Mitsubishi Heavy Industries|Mitsubishi]] TD06-17C 8cm² [[turbocharger]]<ref name="HMM-SS"/> and [[Garrett AiResearch|Garrett]] water/air [[intercooler]] attached to a 4.3L ''[[Chevrolet 90° V6 engine#Turbocharged LB4 4.3L V6|LB4]]'' [[V6]] engine featuring upgrades that included hypereutectic pistons, nodular iron main caps, upgraded head gaskets, [[intake manifold]]s, [[exhaust manifold]]s, and a {{convert|48|mm|in|1|abbr=on}} twin-bore throttle body from the [[Chevy 350|5.7L Chevrolet small-block engine]]. All Syclones and Typhoons used the [[Turbo-Hydramatic#THM700R4 / 4L60 / 4L60E / 4L65E / 4L70E|4L60]] 4-speed [[automatic transmission]]. A [[BorgWarner]] 4472 all-wheel-drive transfer case splits torque with 35% of power going to the front and 65% of power to the rear wheels.<ref name="HMM-SS"/> Both trucks featured sport modifications to the standard suspensions. The Syclone was the first production truck to receive a 4-wheel [[anti-lock braking system]].<ref>{{cite web |last1=Huizenga |first1=Paul |title=Storm on the Horizon: Tracing Today's Super SUV Origins |url=https://www.drivingline.com/articles/storm-on-the-horizon-tracing-todays-super-suv-origins/ |website=Driving Line |date=27 February 2018 |publisher=Nitto Tire |access-date=19 December 2019}}</ref> With this engine, the Syclone produces {{Convert|280|hp|kW|0|abbr=on}} and {{convert|350|lbft|Nm|0|abbr=on}} of torque.<ref name="HMM-SS"/> The Syclone, when new, was capable of accelerating from 0–60 mph (0–97 km/h) in 5.3 seconds and could do a quarter-mile run in 13.4 seconds at {{Convert|98|mph|km/h|0|abbr=on}} according to ''Car and Driver''<nowiki/>'s comparison test.

The Syclone and Typhoon's gauge cluster is the same one as used in the [[Pontiac Sunbird]] Turbo, which was discontinued in 1990, one year before the Syclone was introduced.

The 1991 Syclone was only available in black. For the upcoming 1992 production, a wider range of colors was to be offered; however, the Syclone was cancelled before full production could begin. In total, 2,998 Syclones were built.<ref>{{cite web | url = https://www.hemmings.com/blog/2016/03/07/faster-than-a-corvette-gmcs-syclone-sport-truck-celebrates-a-quarter-century/|archive-url = https://web.archive.org/web/20190327010743/https://www.hemmings.com/blog/2016/03/07/faster-than-a-corvette-gmcs-syclone-sport-truck-celebrates-a-quarter-century/ | archive-date = 2019-03-27 | title = Faster than a Corvette?

The first 1992 Syclone was used for [[United States Department of Transportation|DOT]] crash testing while the remaining two are privately owned.

=== Saudi Syclone ===
During the 1991 Syclone production, roughly 150 Syclones were officially exported by GMC. Out of the 150 trucks, there were an estimated 113 destined for resale in the Middle East and were modified with a metric dash cluster, leaded fuel chip, and a [[Resonator#Automobiles|resonator]] in place of the [[catalytic converter]]. These 113 trucks were shipped to [[Saudi Arabia]] to be sold as export sales. These 113 trucks were known as the Saudi Syclones.<ref>{{Cite web|date=2020-04-26|title=1991 GMC Saudi Syclone Edition {{!}} International SyTy Registry|url=https://internationalsytyregistry.com/historical-truck-info/conversion-trucks/1991-gmc-saudi-syclone/|access-date=2021-01-09|language=en-US}}</ref> Not all of the exported Saudi Syclones were sold immediately overseas. Out of the 113 Saudi Syclones, 31 trucks remained unsold and were eventually brought back to the United States. Rather than selling the 31 trucks to the public, GMC set up a lottery where employees could enter their name to be drawn to have the chance at purchasing a Saudi Syclone as a significantly reduced price ($12,500) and had to take delivery through a dealership. It is alleged that not many employees knew of the lottery to purchase one of the Saudi Syclones, so almost everyone who entered got the chance to buy one, which upset a lot of GM employees in various other divisions who felt they missed out. The remaining 69 trucks were distributed throughout Europe for sale where a small number ended up in a German compound for sometime. GMC, desperate to be rid of them, sold them on a "make us an offer" basis. Lucky purchasers managed to get hold of one for a few thousand dollars under their market value.

In 2009, a poor-condition GMC Syclone was scrapped under the U.S. federal government [[Car Allowance Rebate System]] (colloquially known as "cash for clunkers"), despite being highly collectible.<ref>{{cite news|url=http://jalopnik.com/5462441/morons-clunkerize-rare-gmc-syclone-super-truck|title=Morons Clunkerize Rare GMC Syclone Super Truck| first = Matt | last = Hardigree | publisher=[[Jalopnik]] |date= Feb 2, 2010 |access-date=2010-02-02}}</ref>
