Question: The car involved in the 2009 Singapore Romanian diplomat incident was manufactured in what country?

<P0-S0> The Williams FW31 is a Formula One motor racing car, designed and built by WilliamsF1. <P0-S1>  The "AT&T Williams" team used the FW31 to compete in the 2009 Formula One season. <P0-S2>  The car was unveiled on 19 January 2009 at the Autódromo Internacional do Algarve circuit in southern Portugal, and was first driven by the team's test driver Nico Hülkenberg. <P0-S3>  It was a mid-field runner, in contention for points on many occasions when driven by Rosberg, but rarely contending for podiums. <P0-S4>  Rosberg could have finished in third position at Marina Bay during the 2009 Singapore Grand Prix if he had not run wide on the exit of the pit lane and received a penalty. <SEP> <P1-S0> The 2009 Singapore Grand Prix (formally the 2009 Formula 1 SingTel Singapore Grand Prix) was a Formula One motor race held at the Marina Bay Street Circuit in Singapore on 27 September 2009. <P1-S1>  The 61-lap race was the fourteenth round of the 2009 Formula One season. <P1-S2>  It was the second Singapore Grand Prix to be part of a Formula One Championship and the tenth Singapore Grand Prix overall. <P1-S3>  It was also the second Formula One race to be held at night. <P1-S4>  The race was won by McLaren-Mercedes driver and reigning World Champion Lewis Hamilton. <P1-S5>  Toyota's Timo Glock finished second and 2008 race winner Fernando Alonso took third position, making this the only race of the season with neither a Brawn nor a Red Bull driver on the podium. <P1-S6>  This was also the last race of 2009 for Glock, as he was injured during qualifying for the Japanese Grand Prix and was replaced by test driver Kamui Kobayashi. <P1-S7>  Heikki Kovalainen scored his last ever World Championship points at this race. <SEP> <P2-S0>  The vehicle, a black Audi A6 bearing diplomatic license plates, was later identified as being driven by Dr Silviu Ionescu, at the time Chargé d'Affaires ad interim of the Romanian Embassy in Singapore. <P2-S1>  At approximately 3 am, the vehicle ran two red lights and hit the pedestrians on a pedestrian crossing, injuring two and killing one. <P2-S2>  Approximately 40 minutes after the incident, Ionescu reported the vehicle as being stolen. <P2-S3> The Singapore Romanian diplomat incident occurred on 15 December 2009, when three pedestrians were struck in a hit-and-run in the Singapore suburb of Bukit Panjang. <P2-S4>  The car was later found abandoned in Sungei Kadut approximately 4 hours after the collisions. <SEP> <P3-S0> The Audi A6 is an executive car made by the German automaker Audi AG, now in its fourth generation. <P3-S1>  As the successor to the Audi 100, the A6 is manufactured in Neckarsulm, Germany – and is available in sedan and wagon configurations, the latter marketed by Audi as the "Avant." <P3-S2>  Audi's internal numbering treats the A6 as a continuation of the Audi 100 lineage, with the initial A6 designated as a member of the C4-series, followed by the C5, C6, and the C7. <P3-S3>  The related Audi A7 is essentially a coupé-hatchback version of the C7-series A6, but is marketed under its own separate identity and model designation.
