Performance
Recently Ultima have focused their marketing efforts on record-breaking activities using a model equipped with a 640 bhp (477 kW) American Speed engine, which is called the Ultima GTR640, and subsequently, a 720 bhp (537 kW) engine which is called the GTR720. As a result, they have established the following official, independently verified records for a production car equipped with road tyres and exhaust:
- Fastest 0-60 mph (97 km/h) time: 2.6 seconds
- Fastest 0-100 mph (160 km/h) time: 5.3 seconds
- Fastest 30 mph (48 km/h)-70 mph (110 km/h) time: 1.8 seconds
- Fastest 100 mph (160 km/h)- 0 mph time: 3.6 seconds
- Fastest 0-100 mph (160 km/h)- 0 mph time: 9.4 seconds
- Best performance on a skidpad: 1.176g lateral grip in a 200 ft (60 m) circle.
- Fastest road car over the 1/4 mile: 9.9 seconds @ 143 mph (230 km/h)
Due to its kerb weight of 990 kg (2,183 lb), the power-to-weight ratio for the GTR720 is 727 hp (542 kW) 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), it's also lesser to the Caparo T1. However, the Ultima chassis is rated for engines up to 1,000 bhp (700 kW) and some of Ultima's customers have fitted engines producing 1,000 bhp (700 kW) or more, for a power-to-weight ratio of over 1,000 hp (746 kW) per tonne, which is approximately twice the power-to-weight ratio of the aforementioned cars and nearly the same as the Caparo T1's (1170 hp/tonne, but this is a "dry" tonnage and the hp/tonne would be reduced once oil, coolant, gasoline, etc. are added, compared to the Ultima figures above which are "wet" weights).
The GTR720 has been independently timed lapping the Top Gear test track in 1 minute 12.8 seconds, which is over 2 seconds faster than all other times listed on the Top Gear television programme's Power Board. 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.

Famous quotes containing the word performance:
“To vote is like the payment of a debta duty never to be neglected, if its performance is possible.”
—Rutherford Birchard Hayes (18221893)
“Nobody can misunderstand a boy like his own mother.... Mothers at present can bring children into the world, but this performance is apt to mark the end of their capacities. They cant even attend to the elementary animal requirements of their offspring. It is quite surprising how many children survive in spite of their mothers.”
—Norman Douglas (18681952)
“They say all lovers swear more performance than they are able, and yet reserve an ability that they never perform; vowing more than the perfection of ten, and discharging less than the tenth part of one.”
—William Shakespeare (15641616)
