Ultima focused their marketing efforts on record-breaking activities using a model equipped with a American Speed engine, called the Ultima GTR640, and subsequently, a at 6700 rpm and a maximum torque of at 4400 rpm
Chevy V8 engine called the GTR 720. As a result, they established the following official, independently verified records for a production car equipped with road tyres and exhaust: • Fastest 0– time: 2.6 seconds the
power-to-weight ratio for the GTR720 is per tonne, which is a better ratio than the
Bugatti Veyron,
Enzo Ferrari,
Ascari A10,
Koenigsegg CCX or
CCGT, but less than the
Koenigsegg CCXR or the
Caparo T1. However, the Ultima chassis is rated for engines up to and some of
Ultima's customers, notably
Jeff Schwartz, have fitted engines producing or more, for a power-to-weight ratio of over per tonne, which is approximately twice the power-to-weight ratio of the aforementioned cars and nearly the same as the
Caparo T1's ( per tonne, but this is a "dry" tonnage and the bhp PS kW/tonne would be reduced once oil, coolant, gasoline, etc. are added, compared to the Ultima figures above which are "wet" weights). There are also other model designations for the kits, including the GTR 660 and GTR 730. In 2007, the GTR720 was independently timed lapping the
Top Gear test track in 1 minute 12.8 seconds, at least one second faster than all other times listed on the
Top Gear television programme's
Power Board at the time. In October 2009 Ultima set another time of 1 minute 9.9 seconds, but this time in a configuration not suitable for use on public highways. Ultima have been keen to point out that this time is faster than those set by both the Ferrari FXX and the Caparo T1; of which neither were deemed to be acceptable road cars by the Top Gear presenters shortly after these times were set. In 2011,
Romanian workshop Black Falcon Cars mated an Ultima GTR chassis and a modified
Porsche GT3 transmission with a
Chevrolet V8 turbocharged by Nelson Racing Engines to achieve on racing fuel and made it fully
road legal under the brand name Black Falcon SBC-TT1750. In 2015 the GTR and Can-Am names were retired and replaced by the
Ultima Evolution range, which represents a complete reengineering of the package. == Trims by Power Output ==
