Toyota has reversed its decision to field only one TS030 HYBRID in the World Endurance Championship.
The Cologne-based Toyota Motorsport GmbH squad had been forced to downscale its plans to run two 2013 versions of its petrol-electric hybrid for financial reasons earlier this month.
It has now been able to go back on that and ramp up its assault to two cars after running one car in the final five races last season.
TMG technical director Pascal Vasselon said: "We were expecting to run one car and now we have two, which is great."
Toyota confirmed last year that it would retain its 2012 driver line-up of Alex Wurz, Nicolas Lapierre and Kazuki Nakajima and Anthony Davidson, Stephane Sarrazin and Sebastien Buemi.
The two Toyotas and two Audi R18 e-tron quattros head a 32-strong WEC entry, which is two up on last year's inaugural series.
Series boss Gerard Neveu said: "Thirty-two cars is an extraordinary entry and we are happy to have an increase in numbers and, I believe, quality."
There are only six full-season LMP1 entries, the privateer Rebellion Racing and British Strakka Racing squads fielding one Lola-Toyota and one HPD respectively.
There are 12 LMP2s entered, including series newcomer HVM Status GP and two of the Kodewa-developed Lotus T128 coupes.
The GTE Pro entry of six cars is made up of a pair of factory entries from Ferrari, Porsche and Aston Martin respectively.
