Thundercat

: "For the motorcycle, see Yamaha YZF600R"

The Thundercat is a snowmobile produced by Arctic Cat in the 1990s. In its time it was considered one of (if not, the) fastest and the most powerful sleds available (175hp) . This is partially due to its big-bore case-reed triple cylinder engine available in 900 or 1000 cc's. The Thunder Cat has since been replaced by the ZR900 in 2003 and in 2007 was replaced by the hp F1000. The Thundercat can still run with many of the fastest snowmobiles available currently, although it may have a tough time competing against the Ski-Doo Mach Z 1000 or the Yamaha Apex/Attak 1000 4-stroke. the stock arctic cat thundercat 1000 can reach speeds of 126 mph.

1993-1995 Thundercat 900 has aws3 chassis.

1996-1997 Thundercat 900 has aws4 chassis.

1998 Thundercat 1000 has aws4 chassis.

1999-2002 Thundercat 1000 has aws5 chassis.

In July 2007, Arctic Cat revived the Thundercat name, affixing it to their new 950cc V-twin motivated ATV (all terrain vehicle). Perhaps appropriately, it is the largest and most powerful ATV ever built.
