Twingo Renaultsport 133 is powered by a naturally-aspirated 1.6 litre 16V engine developed by Renault Sport Technologies. This powerplant delivers 133hp (98kW) at 6,750rpm with 160Nm of torque at 4,400rpm. The unit’s punchy character is reinforced by a characteristic engine note which has been the focus of specific development. The four-into-one fabricated exhaust manifold strikes a perfect balance between acoustics, performance and low emissions.
A sporty, normally-aspirated engine
Twingo Renaultsport 133 is powered by a naturally-aspirated 1.6-litre 16V engine (K4M RS) which delivers 133hp (98kW) at 6,750rpm and 160Nm of torque at 4,400rpm. This free-revving engine offers flexible performance and instantaneous throttle response. At low revs and in the mid-range up to 4,500 rpm, Twingo Renaultsport 133 has lively yet manageable performance for everyday use. Beyond 4,500rpm, Twingo Renaultsport 133 gives full vent to its sporting character with true punchy performance. The car accelerates from standstill to 62mph (100kph) in 8.7 seconds, while top speed is 125mph with the rev-limiter at 7,000rpm. Fuel consumption is a low 40.4mpg in the combined cycle, equivalent to CO2 emissions of 165g/km.
The 133hp 1.6-litre 16V powerplant has been developed from the 1,598cc petrol engine. The improved power and torque are the result of modifications and improvements to the mechanical components:
The air filling rate has been improved thanks to a specific throttle valve unit and aluminium plenum chamber, plus revised diameters and lengths for the air-inlets.
To improve air intake and facilitate gas flow, research was carried out on the aerodynamics of the valve seats. The calibration of the camshafts was revised to a longer opening of the valves and higher lift (11mm compared to an average of 9mm).
The design of the combustion chamber and piston produces a high compression ratio of 11.0:1, leading to enhanced combustion and efficiency, as well as lower emissions. The continuously-variable inlet camshaft improves performance right across the rev range. The actuator varies the timing setting to optimise valve opening and closing. This system operates continuously through 44° of crankshaft rotation.
Sports performance and acoustic enjoyment
The experts at Renault Sport Technologies have worked hard to give Twingo Renaultsport 133 an engine note in keeping with its sporting character. The engine noise is minimal at low revs, but builds mid-way through the rev range to become ‘fiery’ when pushed to its limits.
The four-into-one exhaust manifold, fabricated from steel tube, is being patented by Renault Sport Technologies. The technological feat is to have combined four long steel tubes in such a restricted space. This architecture offers an excellent trade-off between acoustics, performance and emissions. Indeed, the engine has been designed to be able to comply with Euro5 legislation.
Twingo Renaultsport 133 is fitted with an evolution of the five-speed manual gearbox (JR5). The closely-spaced ratios are linked to a fast and precise shift mechanism to favour crisp acceleration in all gears.
THE TWINGO STORY CONTINUES…
Twingo Renaultsport 133 is the latest addition to the Twingo range and reinforces Renault's status as a major player in the European small car market. It is manufactured at the Novo Mesto factory in Slovenia.
Renaultsport expertise packed into a small car
Twingo Renaultsport 133 is the latest model in the Renault Sport Technologies range, and goes on sale in the UK from 5 September and in the third quarter of 2008 in Western Europe. This latest example of Renault’s hot hatch prowess rounds off the Renaultsport family which already includes Clio and Mégane Renaultsport.
With nearly 13,000 registrations in 40 countries in 2007, the Renault Sport range registered an increase in volume of more than 50% compared with 2006.
The arrival of the new Twingo Renaultsport 133 will help the Group expand its presence even further in the hot hatch market. The United Kingdom is the number one market for Renaultsport vehicles, and should account for a third of sales. France, Spain, Italy, Germany and Switzerland are expected to share half of Twingo Renaultsport sales.
The Twingo success story
Twingo was progressively introduced in Europe from June 2007. Up to the end of June 2008, approximately 140,000 cars had been sold which is in keeping with the ambitious objectives it has been set. It stands out as the segment's clear leader in France with sales in excess of 60,000. Twingo also sells very well in Belgium, where it tops its segment, Germany and Holland (second in segment). Twingo enjoys a 10 per cent share of the small car market in Western Europe, which puts it in the top-three. For comparison purposes, the segment share of the first generation Twingo in Europe was 4.5 per cent as of the end of June 2007.
Twingo GT has also proved immensely popular, with a mix of up to 25 per cent in the UK, showing a real appreciation for the sportiest model thus far in the line up.
In addition to rounding off the Twingo range, Twingo Renaultsport 133 reasserts Renault's role as a key player in the small car segment in Europe.
Optimised production lines
Twingo Renaultsport 133 is produced at the Novo Mesto factory in Slovenia which is where all Twingos are manufactured. Novo Mesto enjoys both ISO 9001 and ISO 14001 certification. It applies the Renault Production Way (SPR) and the standard of quality it delivers is as high as that of any Renault Group production facility.
The Renaultsport version is manufactured on the same line as Clio Campus and New Twingo. The three vehicles are based on the same platform, which allowed the facility to adjust quickly to the new model. Some 80 per cent of manufacturing operations are identical between Clio Campus and New Twingo, while 90 per cent are common between Twingo and Twingo Renaultsport.
