Daihatsu has announced next-generation engines for the ASEAN region, benefitting both Indonesia’s Astra Daihatsu Motor (ADM) and Malaysia’s Perodua, JVs where DMC has interest in.
Here in Indonesia, where we’re covering the GIIAS 2015 show live, a version of the new engine made its debut in the recently launched Daihatsu Xenia facelift. That’s the 1NR-VE, a 1.3 litre DOHC engine with Dual VVT-i, 97 hp at 6,000 rpm and 121 Nm of torque at 4,100 rpm.
The 1NR-VE is also available in the Toyota Avanza facelift, which is manufactured by ADM for Toyota. The Avanza, as the car with the senior brand, is also available with a bigger 2NR-VE 1.5 litre engine (104 PS/139 Nm). The replaced engines made 91 PS/117 Nm (1.3) and 103 PS/136 Nm (1.5).
Intake and exhaust Dual VVT-i aside, the new engines feature teflon coating for the pistons (reduces friction), larger water jackets (better cooling, improved combustion, lower noise), roller rocker arm (reduces friction between rocker arm and camshaft) and iridium spark plugs. The roller and water jacket measures combine for 14% reduced engine noise in the Xenia, and fuel savings of up to 15% are claimed.
The base parts of the new engines have been jointly developed by Daihatsu and Toyota. In Indonesia, The new engines will be manufactured on a new line at ADM’s Karawang engine plant; the line incorporating Daihatsu’s production concept of simple, slim and compact (SSC). The company says that costs have been drastically reduced, thanks to the expanded use of local parts.
In Malaysia, we know that Perodua is constructing a RM600 million engine plant at the Sendayan TechValley near Seremban, which as of last month was 80% complete. The facility will be ready by the fourth quarter of this year and will produce the 1.3 and 1.5 litre NR engines. Perodua doesn’t use VVT-i branding, so expect a different term – Dual-DVVT perhaps?
“Technologies will be developed for many different applications, and will also be incorporated in the vehicles of Perodua, a local joint venture in Malaysia. In Malaysia, the new engines will be manufactured at a new engine company that will commence operation in mid-2016. The new company’s plant will also follow the concept of SSC,” Daihatsu said in a statement.
