The Mosler MT900 GT3 is a Mosler MT900-based GT3-spec race car built by Mosler.
Launched in late 2006, the Mosler MT900 GT3 was an attempt by Rollcentre Racing to adapt the MT900R for compliance to the new FIA GT3 category used in various championships. However, the lack of production Moslers led to the FIA rejecting the homologation and forcing Rollcentre to turn elsewhere. The car is allowed into the International GT Open, Australian GT Championship and Belcar series along with the British GT championship which runs to GT3 rules, but has not been approved for other series which use the GT3 category. MT900R GT3 cars use the LS7 7.0L V8 (427 cui) rather than the LS1 5.7L (350 cui) version from the original MT900R.
Added in the December 2015 Santa's Gift Update, the Mosler MT900 GT3, renamed to Mosler GT3, is the first Mosler car in the game and the second-to-the-last car added in the update, before the TRION NEMESIS.
Expected to be the highest-performing non-Elite Car in Class A that can be purchased with Credits, the Mosler GT3 has a starting rank of 1481, a MAX rank of 1656, and a MAX+PRO rank of 1765. The car receives a small Tuning Kit bonus of +38 points. Its main rivals are the Ferrari 330 P4, McLaren 675LT/9FF GT9 VMAX, Aston Martin One-77, and McLaren F1 XP-5.
The Mosler GT3 has a Speed Modification of 91.60%, shared with the Lamborghini Estoque, McLaren F1 XP-5, and TRION NEMESIS. Along with the Range Rover Evoque Coupe HSE Dynamic, the GT3 is the first non-Class S car added into the game which has a Speed Modification, and is one of only three Class A vehicles to have a Speed Modification (the other two being the Mercedes-AMG C 63 Coupe Touring Car 2014 and Icona Vulcano V12 Hybrid).
As expected for its placement, the Mosler GT3 features extraordinary performance, complete with improved acceleration/launch over the McLaren 675LT (3.5 seconds to maximum speed at a standing start with Level 3 Nitro at MAX+PRO+Tuning Kit), as well as heavily similar top speed stats. The Mosler GT3 also has among one of the best handling/drifting capabilities in Class A, capable of having drifting capabilities similar to the Ferrari Enzo Ferrari. It also retains the superior nitro power of the McLaren 675LT, complete with the same long-lasting nitro (5/10/15). Overall, the Mosler GT3 effectively serves as a replacement for the McLaren 675LT in most cases.
At MAX+PRO with a Tuning Kit, the Mosler GT3 is actually slightly slower than the McLaren 675LT by around 2.9 kph (1.8 mph), but makes up for this with superior acceleration and handling; in fact, the Mosler GT3 has almost the same real top speed as a MAX + PRO McLaren P1™ GTR at MAX+PRO+Tuning Kit. A three-way comparison between the McLaren 675LT, Mosler GT3, and McLaren F1 XP-5 shows the F1 XP-5 to be superior over the other two cars in all tracks, while the 675LT becomes slightly superior over the GT3 in a few non-complex tracks (e.g. French Guiana).
What's worth noting is that the Bentley EXP10 Speed 6 and Mosler GT3, when upgraded to the same levels, have the same total speed (481.5 km/h).
The Mosler GT3 remains one of the most useful non-Elite Class A cars to date, complete with its competitiveness in Time-Limited Events and Multiplayer League races, although not as competitive as the BMW 3.0 CSL Hommage, McLaren Mercedes MP4-25, and SIN R1. Due to its higher starting rank, the Mosler GT3 isn't as useful in Multiplayer League races as the 675LT, which can compete with lower-ranked cars like the Range Rover Evoque Coupe HSE Dynamic and Shelby Cobra 427.
Costing 1,500,000 to purchase and 3,215,200 to max out, the Mosler GT3 currently stands as the most expensive credits-only Class A car, even more expensive than the Bentley EXP10 Speed 6, Jaguar XJ220S, and Savage Rivale GTR.
