"With names like “Andretti,” “Fittipaldi,” and “Kanaan” on the roster, the Andretti-Green Racing ALMS team no doubt has excellent pedigree, which extends to the #26 car, an ARX-01b resulting from the highly successful collaboration between Acura and chassis constructor Courage. Leading the team from their Indianapolis headquarters is IndyCar champion Michael Andretti, son of Mario Andretti. In 2008, #26 had a strong showing, finishing many times in the top ten and taking first in class for the final race of the season at Laguna Seca. It’s hard to miss the sharp livery, predominantly black with yellow and blue accents, in your rearview mirror; but with 16-player races available and a host of ALMS cars in Forza 4, it’s entirely possible (and a lot of fun) to recreate many of the same grids that #26 faced during its real-life career."
—Official description (#26 Andretti-Green Racing ARX-01b)[1]

The 2008 Acura ARX-01b is an LMP2 race car by Acura.

It appears in Forza Motorsport 3 and Forza Motorsport 4.

Variants[]

The ARX-01b is featured in three livery variants in each game appearance:

  • 2008 Acura #15 Lowe's Fernandez ARX-01b
  • 2008 Acura #26 Andretti-Green Racing ARX-01b
  • 2008 Acura #66 de Ferran Motorsports ARX-01b

Synopsis[]

The ARX-01, Acura's first foray into racing, was unveiled at the 2006 North American International Auto Show, with Acura announcing their intention to campaign the car in the 2007 American Le Mans Series (ALMS). The car was a collaboration between Honda Performance Design (HPD) and Wirth Research, with the former focusing on the naturally aspirated 3.4L V8 engine and the later focusing on the chassis, which is based on a Courage LC75. 2007 would end up being a development year for the car, with Andretti Green Racing and Highcroft Racing focusing on developing the chassis and Fernández Racing utilizing a modified Lola B05/40 (dubbed the B06/43) to develop the engine.[2]

The car went through multiple iterations over a 5 year life-span from 2007 to 2011, featuring in both the ALMS and the Le Mans Series (including Le Mans itself). The initial development year car was called the 01a, while its successor was called the 01b. In 2010, an update to aerodynamics caused the car to be renamed to the 01c. A year later, when the LMP2 regulations were overhauled to only allow production engines, two new variants were developed, the 01d with a 2.8L turbocharged V6, and the 01e, which kept the V8, but was now intended for LMP1 use. The final iteration was announced later that year as the 01g, essentially a cost-capped version of the 01c, but with the engine of the 01d.[3]

All 3 cars featured in the Motorsport series competed in the ALMS during the 2008 season. The #26, piloted by 7 different drivers over the course of the season, finished in 4th thanks in part to 2 class wins in the last 3 races of the season. The #15, driven by Adrián Fernández, Luis Díaz, and Michel Jourdain Jr. (Petit Le Mans only) finished just behind in 5th place. Finally, the #66, with drivers Gil de Ferran, Simon Pagenaud and Scott Dixon (Petit Le Mans only), brought up the rear in 6th. Overall, Acura finished second in the constructor's standings, only losing out to Porsche by a single point.[4]

Only the Fernández outfit would continue using the 01b into 2009, as de Ferran and Highcroft (which finished 2nd in the 2008 standings to Team Penske's RS Spyder Evo) would move up to LMP1 with the ARX-02a, while Andretti would leave the series as Acura decided to end their relationship due to mixed results. The car would dominate the season, taking 8 out of 10 class wins and the title from the only other full entry in the class, Dyson Racing and their B09/86.[5]
