Tuned Audi RS3 Drag Races Audi RS7

RS3’e yalnızca ECU kalibrasyonu yapılmış.

Otomobil üreticileri, araçlarının her zorlu koşulda çalışmasını garantilemek için kullandıkları motorları bir miktar kısmak zorunda kalıyorlar. Bu konuda ECU kalibrasyonu yapan firmalar devreye giriyor. Aracın bulunduğu bölgeye göre, motor ve şanzımanı kalibre eden bu yazılım şirketleri, motorun potansiyelini yaşamanızı sağlıyor.

Son dönemlerde, BMW’nin 1.6 litrelik B48 motorunun 170 bg’den 300 bg seviyelerine çıkarılması gibi büyük artışları sık sık duyuyoruz. Bu RS3’te ise, 5 silindirli 2.5 litrelik motordan 100 bg ek güç almayı başarmışlar. Stok hâlde 400 bg ve 500 Nm üreten güç ünitesi, artık 500 bg ve 630 Nm sunuyor.

Tamamen stok hâlde drag pistine katılan RS7 Performance ise 630 bg güç ve 850 Nm tork üretiyor. Gösterişli sedanın 0-100 km/s hızlanması, RS3’ün stok hâlinden 0.4 saniye daha hızlı şekilde, yalnızca 3.4 saniye sürüyor.

Farklı sistemlere sahip olmalarına rağmen her iki araç da dört tekerlekten çekişe sahip. RS3 enine monte edilmiş bir motora sahipken, RS7’nin motoru uzunlamasına konumlandırılmış. Ayrıca, RS7 yaklaşık 500 kg daha ağır olduğu için epey çekişmeli bir kapışma olacağı aşikâr.

İlk drag yarışını RS7 kazanırken, ikincisini RS3 kazandı ve üçüncü start’ın ardından RS7’nin galibiyeti kanıtlandı. Fakat, aradaki fark tahmin edebileceğinizden çok daha küçüktü. Büyük Audi, çeyrek mil (400 metre) yarışını 11.3 saniyede tamamlarken, kalibre edilmiş RS3 11.5 saniyelik bir süreyle hemen arkasındaydı.

Günümüzde dijitalleşen otomobillerin yakıt ve ateşleme zamanlamasından multimedya sistemine kadar her şey milyonlarca satırlık kodlar ile sağlanıyor. Hem performans artışı hem de bazı ek özelliklere kavuşmanızı sağlayan bu kalibrasyonun fiyatı ise yaklaşık 1000 £ (40 bin ₺) seviyesinde.
