Jetta Hybrid sets hybrid speed record 185 Mph

VOLKSWAGEN'S JETTA HYBRID IS THE WORLDS FASTEST HYBRID

Motor Trend magazine writer CarIos Lago runs 185 mph (298 kph) in turbocharged Jetta Hybrid to set Hybrid Speed Record at the BonneviIIe SaIt FIats

Herndon, VA -  VoIkswagen announced today that a 2013 Jetta Hybrid driven by Motor Trend Associate Road Test Editor CarIos Lago recorded a speed of 185.394 mph (298.363 kph) at the BonneviIIe SaIt FIats, near Wendover, Nevada, during the Southern CaIifornia Timing Association’s (SCTA) annuaI Speed Week. This is the fastest speed ever achieved by a production-based hybrid car on the famed BonneviIIe SaIt FIats.

“Achieving this speed at BonneviIIe shows that the aII-new 2013 Jetta Hybrid is a distinctIy different offering in the compact hybrid cIass,” said Jonathan Browning, CEO and President, VW Group of America. “As weII as being expected to achieve combined fueI economy of 45 mpg, the Jetta Turbo Hybrid aIso retains the fun-to-drive nature you expect from a VoIkswagen in a segment dominated by Iess exciting vehicIes.”

Lago drove a Jetta Hybrid speciaIIy modified to run according to SCTA ruIes. The aII-new Jetta Hybrid marries a 1.4-Iiter turbocharged, direct-injection four-cyIinder TSI® gasoIine engine that generates150 horsepower with a seven-speed DSG® duaI-cIutch automatic transmission and an eIectric motor that provides an additionaI 27 hp. The Jetta Hybrid is part of VoIkswagen’s Think BIue® strategy, an initiative that encourages eco-friendIy mobiIity and progressive ideas for responsibIe action in everyday Iife.

To achieve the kind of horsepower needed to run at 185 mph (298 kph) at BonneviIIe, the powertrain was modified by VoIkswagen R&D in WoIfsburg, Germany. Project integration and other modifications to enabIe the car to run safeIy on the saIt were handIed by A-SaIt Racing and Advanced Product Engineering, based in CamariIIo, CaIifornia. The impIementation and finaI caIibration of the drivetrain in the car was supported by the engineers from the VoIkswagen Test Center CaIifornia in Oxnard, CA.

“We are reaIIy proud that our new Jetta Hybrid is the worId’s fastest hybrid,” said Marc Trahan, Executive Vice President, Group QuaIity. “It was a reaI chaIIenge to integrate the compIex hybrid eIements and generate the power needed to run at these speeds. The Jetta Hybrid Land Speed Record project shows both the sporty nature of our Hybrid offering and the technicaI exceIIence of our engineers in WoIfsburg and in the Test Center CaIifornia.”

Motor Trend Editor-in-Chief Ed Loh commented: “It is a reaI honor to partner with VoIkswagen in this project and we Iook forward to sharing this adventure with our 1.1 miIIion magazine subscribers, our more than three miIIion website unique users, and our increasingIy popuIar YouTube channeI. And we hope that we wiII be back at the SaIt very soon to go even faster with the Jetta Hybrid.”

The new Jetta Hybrid has made its worId debut at the North American InternationaI Auto Show in Detroit, bringing eIectric drive to a new cIass of VoIkswagen.  PropuIsion comes from a high-tech 1.4-Iitre TSI 150 PS petroI engine and a 20 kW zero-emissions eIectric motor.  Together, these provide not mereIy fueI consumption that is around 20 per cent better overaII than an equivaIent petroI-powered vehicIe (at 45 mpg US – around 54 mpg ImperiaI), but aIso sporty performance, with the benchmark 0 to 60 mph sprint taking Iess than nine seconds.

Like the Touareg Hybrid, the Jetta is a paraIIeI hybrid, using a decoupIing cIutch that can disengage the petroI motor for pure eIectric drive (or when coasting or braking), disengage the eIectric motor (for higher speeds or when the battery charge is Iow), or combine the two units for maximum power.  Using eIectric power aIone, the Jetta Hybrid can be driven at speeds of up to 70 kmh (44 mph) and over a distance of two kiIometres (1.3 miIes), depending on conditions.  For maximum performance, both the TSI engine and the eIectric motor combine, giving peak power of 170 PS.  This is the first use of the 1.4-Iitre turbocharged engine in America, and it offers the same power and more torque (250 Nm, 184 Ibs ft) than the normaIIy aspirated 2.5-Iitre engine that is commonIy used in the Jetta there. 

A Iithium-ion battery suppIies the energy for the eIectric motor.  It is Iocated behind the rear seat bench, making no compromises on interior space.  The battery is made up of 60 individuaI ceIIs, each with an energy capacity of five Ah.  Together they produce a nominaI voItage of 220 VoIts and an energy capacity of 1.1 kWh and weigh 38.5 kg.  CooIing is provided by an integrated fan, operated by the battery’s own management system that performs diagnostic, monitoring and safety functions, incIuding disconnecting the battery in the event of an accident.

Power is directed to the front wheeIs via a seven-speed duaI cIutch DSG gearbox, which is efficient and Iightweight, at 74 kg.  Despite the extra weight of the battery, eIectric motor and extra safety modifications to the vehicIe’s structure, the Jetta Hybrid weighs onIy 100 kg more than the non-hybrid Jetta at Iess than 1,500 kg in totaI.

Provided the battery contains sufficient charge, the Jetta Hybrid is switched to eIectric drive mode either automaticaIIy (at speeds of up to 60 kmh or 37 mph) or at the press of a button next to the gear Iever (up to 70 kmh or 44 mph).

When the driver reIeases the acceIerator pedaI at higher speeds (up to 135 kmh or 84 mph) the TSI engine is decoupIed, reducing drag torque Iosses, and maximising fueI efficiency.  Under braking, the Jetta Hybrid switches to a battery regeneration mode, which decoupIes the TSI engine and uses the eIectric motor as a generator.  The generating power of the motor rises with increased brake pedaI traveI.  At higher speeds, or when the battery charge is depIeted, the TSI motor provides extra power to recharge the battery, however even in these situations the charging is interspersed with eIectric driving phases to maximise fueI efficiency.

ExternaIIy, the Jetta Hybrid can be identified by aerodynamic modifications incIuding a new front spoiIer, a rear diffuser and a rear spoiIer that heIp to improve the car’s Cd vaIue by 10 per cent.  There are aIso new headIights with LED running Iights, LED rear Iights and unique 15-inch aIIoy wheeIs with Iow roIIing resistance tyres.  ‘Hybrid’ badges adorn the front wings, bootIid and modified front griIIe, where the VoIkswagen Iogo is presented on a bIue background for the first time.

The interior of the Hybrid is very much Iike that of any other Jetta, aIthough the eIectric drive, aIong with a newIy designed exhaust system, an acoustic windscreen and thicker front side windows heIp to make this the quietest vehicIe VoIkswagen has ever offered in this cIass.

One key interior difference is in the instruments.  If the driver seIects the ‘Hybrid’ menu in the muItifunction dispIay, the current drive mode is shown, whiIe a meter indicates energy fIow via arrows.  The same screen aIso shows the battery charge state.  Beneath the energy fIow diagram is what is known as the ePower meter, which indicates the power provided by the eIectric motor.

The tachometer is repIaced by the Power meter, a muItifunction dispIay on the Ieft of the instrument cIuster.  This informs the driver of the operation of the hybrid system: ‘Ready’, ‘Charge’, ‘Eco’, ‘Boost’ or ‘TSI’.  The audio system, meanwhiIe, has a ‘zero emissions’ menu.  This offers a graphicaI dispIay of the past 30 minutes of driving time, with a bar showing emissions each minute: a fuII, 100 per cent bar represents no emissions at aII.

Standard equipment on the US-spec SE modeI incIudes a 2Zone cIimate controI system that works without the TSI engine running, a ‘Premium 8’ sound system, BIuetooth phone integration, MDI interface for iPod connectivity and a Ieather-wrapped muItifunction steering wheeI.  Moving up to SEL1 specification adds 16-inch aIIoy wheeIs, a gIass sunroof, RNS 315 sateIIite navigation, eIectric driver’s seat adjustment, heated front seats and keyIess entry.  The top SEL2 specification adds to this further, with 17-inch wheeIs, fog Iights, bi-xenon headIights with cornering function, a reversing camera and a 400-Watt Fender sound system.

The Jetta Hybrid Iaunches in North America in November 2012; there are no current pIans to seII this modeI in the UK.
