1.2 8v vs 1.0 and 1.4 Boosterjet: which engine is more reliable?
According to our risk index, the 1.0 and 1.4 Boosterjet carries less risk than the 1.2 8v: 6/100 (low risk) versus 36/100 (moderate risk). The 1.2 8v has 1 documented serious fault, the main one being «Damaged cylinder head gasket (coolant loss and overheating)»; the 1.0 and 1.4 Boosterjet has no documented serious faults.
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.2 8v reliable?
The 1.2 8v (D7F) is a simple naturally aspirated engine of 54 to 60 hp, with a timing belt, which Renault fitted from 1996 to the Twingo, Clio II and Kangoo. No catastrophic failures are documented; what owner reviews mention most often are the sensors, the cylinder head gasket, the coil packs and the occasional oil drip.[1][2][3]
See the 5 of the 1.2 8v faultsIs the 1.0 and 1.4 Boosterjet reliable?
The Suzuki Boosterjet (1.0 K10C and 1.4 K14C/K14D) is a turbocharged direct-injection petrol engine with a timing chain, fitted since 2015 to the Vitara, S-Cross, Swift Sport and Baleno, with a 48 V mild-hybrid variant of the 1.4 since 2020. German TÜV inspection reports and the workshops we consulted rate its reliability as high: no widespread fault with the chain, oil, fuel pump or mild-hybrid system is documented.[4][5][6][7][8]
