MG’s NEW GENERATION TF SPORTS CAR

The MG TF is a new generation of the MG F . Britain’s best sports car and introduces a new exterior an all-new suspension design, performing engines and a host of new interior trim and optional colours.

Launched into markets from February with an array of new improvements, the TF is led by its feature specification and driver In the UK market, the MG F has been the best car in the roadster sector for the last six and the TF has been evolved to continue tradition.

The MG styling team, led by the Product Design Director, Stevens, have substantially the exterior style and aerodynamic – the two key influencing factors on purchase

The TF carries a sharper, more and purposeful look, which was in both studio and wind The improved aerodynamic characteristics an integral part in the chassis and maximise the benefits of the new suspension and changes.

The TF has a new front bumper, to reduce front-end lift, a framed lower air intake and the for ‘Fogstar’ fog lamps. All-new projector headlamps complete the appearance.

At the rear, an integrated lip spoiler incorporating a high-mounted lamp flows from the deck. The TF is lower with a dynamic appearance, assisted by its sill features and crisply-shaped air

A crucial aspect of the TF ’s engineering was the requirement for a new suspension design. A new coil spring suspension and rear axle replaces the MG F’ s Hydragas system to produce a responsive and involving set-up, to produce a completely enjoyable experience. An optional Sports Pack permits greater of driver involvement and further handling performance.

The MG TF is a new generation of the MG F . recognises the ‘real world’ and practicality required of a fully-functioning sports car. The modified and rear subframes are solid-mounted and the new features a 10mm lower This benefits appearance, and handling with its lower of gravity.

The body structure has stiffened in crucial areas to a 20% more rigid shell, an improvement in windscreen header Steering is now more responsive, a completely new tune for the speed-sensitive Power Assisted Steering with a 10% faster geared with revised characteristics to a more progressive steering throughout the car’s speed On ABS equipped cars, braking have been shortened by

A four-model range provides with a spectrum of performance, affordability and specification. Designated by closely linked to their output, the range includes the TF 115, the well-appointed 1.8-litre TF the TF 120 Stepspeed with multi-function CVT auto and the range-topping TF 160 with the Variable Valve Control K engine.

The TF range spans a to 137mph/220km/h speed range with improvements to performance, and CO 2 .

New paint colours – XPower and Le Mans Green – are available on MG TF . Trophy Blue and Trophy now extended to the entire range. TF introduces three new optional colours – in blue, grey and and new trim fabrics – Sebring and Three new interior colours to Ash – Tan, Grenadine and Smokestone – are with matching tonneau for when the hood is folded.

New alloy wheels include an 16 design and the option of an ultra-lightweight.

Rob MG Rover Group’s Product director, explained: The mid-engined MG F has a great success and the new TF builds on strengths to create a car which embodies MG’s passion for a fun and driver-rewarding road car experience. I believe the new MG TF can produce even exhilaration than its competitors.

The MG TF built will carry a VIN (Vehicle Identification Number) following an MG tradition that has the last three numbers of the telephone number – is 0121 475 2101. Abingdon MGs 1930 were started at (Abingdon 251), with MG ZAs and TF Midgets using a 0501 VIN the company’s BMC Headquarters in Birmingham the 1501 telephone number.

MG TF – THE NEW MG ROADSTER

DEVELOPMENT BACKGROUND

In sports car enthusiasts around the were delighted by the launch of the MG F . marked the return of the MG marque to open sports cars for the time since 1980. It firmly established itself as the top sports car in the UK, and began to sell in export markets including Japan and Australia.

Little car development was sanctioned in the BMW-era, from the introduction of the Stepspeed / six-speed) derivative in 1999, as of the 2000MY update. However, MG Rover Group gained its in 2000, the pent-up enthusiasm of MG could at last be directed a high-intensity programme for a new-generation MG F .

The inkling of the new direction came the exclusive MG F Trophy 160 SE model, in January 2001. This from racetrack experience (MG F and MG F Cup championships) and represented the ultimate performance evolution of the existing and body. However the designers and were now thinking well this, with ideas for advances in chassis, body aerodynamics, powertrain and style.

The launch of the MG TF . nearly six months than anticipated, once demonstrates MG Rover Group’s to deliver outstanding products industry-leading time scales and an ethos to be ‘lean, mean and with a ‘will to do’ central to thinking.

The TF retains the ‘real affordability and practicality that set the MG F from rival cars, but is more faithful to the MG brand of ‘Outrageous Fun For All’.

CHASSIS: NEW SUSPENSION

The simple substitution of compact coil springs for the units, with unchanged linkages, had been evaluated some time ago, but would not have delivered the standards of handling and driver central to the latest generation of The challenge of incorporating the latest in suspension geometry, coil and gas-filled dampers within the MG F was taken up.

Advanced computer studies were carried out to the suspension geometry and elasto-kinematic Simulator vehicles confirmed the of the new system. One thorough Main test-driving session with a was all it needed for motorsport enthusiast and MG Product Development Director, Rob to receive the green light for the new concept to be fully engineered to status.

The rear suspension arm pivots from a forward of the subframe, forking at the rear to via firm bushes, above and the hub carrier. This provides wheel location and reacts purely in the vertical plane. A link runs from the base of the hub carrier to a pivot on the rear of the subframe, thus what is effectively a very lower wishbone with a swing radius.

The other comprise the upper suspension arm and a steer-control link mounted of the hub carrier. A new rear anti bar, with modifications to the new configuration, is operated by a short link connected to the hub end of each arm. This new suspension optimum camber control much greater resistance to steer effects.

It is the key to the MG TF ’s more and throttle-adjustable handling, plus its steering ‘centre-feel’. Customers an even more sporting to their TF 120, TF 135 or TF 160 can specify the Pack 1, which has suspension by a further 10mm (i.e. lower than MG F ).

Both and rear subframes were with raised and angled for the top mountings of the coil over units. By moving the lower pivots for the spring units outboard on the upper suspension more conventional leverage and spring rates could be compared with the previous The change also meant the damper forces were within the stiff subframes of being fed into the bodyshell.

The themselves are now solidly-mounted to the bodyshell, as on the Trophy model, contributing to structural

stiffness and precision of Another advantage of the new suspension is it allows a 10mm lower height to operate, to the benefit of stability and handling. A lower of gravity also reduces under acceleration and braking.

At the the wishbone suspension configuration remains similar to MG F . but with camber and parallel tracking in of toe-out, plus revised bushes and a stiffer anti-roll up from 19mm to 20mm to complement the improved steering Tyre life is improved this revised geometry.

It is in the rear suspension (especially on a mid-engined car), that the fundamental changes have made. A completely new multi-link has been engineered to provide control of rear wheel in all conditions to offer exceptionally and responsive control.

SHARPER

The MG F was one of the first cars to exploit the and energy-efficiency benefits of Electric Steering (EPAS). In the major upgrade for the TF . the steering has been 10% ‘faster’ gearing; (the ratio goes from to 17.5:1 with 2.8 turns to lock, from 3.1) for and sharper steering response. In the EPAS control software has further developed.

The speed-proportional now offers more weight at low and a more progressive weight as increases. To further enhance response, the lateral stiffness of the pivot bush on each lower wishbone has been These changes combine the new suspension and increased body to give the new TF even more and confidence-inspiring steering qualities all conditions.

BEEFIER BRAKING

For the new TF 160 MG/AP Racing front similar to those introduced for the MG F 160SE model are specified. The ventilated discs are 304 mm in diameter (up 240 mm) and the special stiffened alloy callipers are red-finished to show the alloy wheel spokes. The TF 160 this competition standard with ABS control. This TF 160 specification is also available on TF 120 and 135 as part of the optional Sports 2 or 3.

On ABS-equipped models (standard on TF 120 and optional on TF 115 and TF 135) the new multi-link suspension layout has facilitated a brake effort balance, the rear brakes to work and reducing stopping distances.

AND TYRES

To fully realise the of the new chassis, an extensive tyre programme confirmed the benefits of the 16 F1 tyre and led to the specification of the new Continental Contact on 15 wheels. All TF models alloy wheels as standard, and all wider tyres at the back at the front to reflect the mid-engine distribution.

Standard equipment on the TF TF 120 and TF 135 are 15 x 6J wheels (eight-spoke on TF 115, on the TF 120 and TF 135) with 185/55 R15 at the front and 205/50 R15 at the rear; the TF 160 has a new design, 16 x 7J wheel with R16 front and 215/40 R16 rear

A comprehensive range of 16 wheel is offered, either individually or as of the Sports Option Packs, a ‘gunmetal’-finish ultra-lightweight 11-spoke A steel spacesaver temporary wheel is standard on the TF 115, TF 120 and TF 135 with the option of the Instant System (IMS) that as standard on the TF 160. IMS comprises a gel and an electric pump.

The alternative for TF 160 buyers is a spare 16x7J, alloy wheel with R16 tyre for temporary use.

AERODYNAMIC BALANCE

The striking new of the TF was carefully honed in the wind as well as in the studio to ensure it excellent lift balance – so to a car’s dynamic behaviour. The new bumper incorporates a carefully-evolved profile, which crucially front-end lift. To balance the rear deck has been to incorporate an effective boot lid

The drag co-efficient, 0.36 in form, reduces to 0.35 the optional lowered suspension Pack, a reduction of 5%, while is reduced by 28%. Lift (front-to-rear difference) has been by 55%.

STIFFER STRUCTURE

analysis of the MG F body structure key improvements to body stiffness to ways of adding to the improved precision and ‘feel’ of the new TF . On-road with accelerometer measurement was to laboratory rig testing and extensive modelling.

The resulting package of offers significant benefits in measured and perceived robustness. In to the solid mounting of both and rear subframes, the front has a diagonal cruciform tubular on the underside, linking its four-corners to the pressing of the underbonnet area.

The behind the centre fascia from the floor tunnel to the cross tube that the steering column has been strengthened. There are two bolt-on braces arranged in triangular across the top of the engine bay. with the new, re-shaped and outer sill and rear pressing, these items the torsional stiffness of the shell by and reduce scuttle shake.

POWERTRAIN

The MG TF has a range of four choices with even all-round standards of performance and response. At the top of the range, the TF 160 has a regular version of the Trophy’s high-output 1.8 VVC developing the same peak of 160Ps (158bhp, 118kW) at an 6900rpm. This replaces the 145Ps (143bhp, 107kW) 1.8 VVC and gains its extra power enhanced breathing.

There is a new intake system with a throttle body, improved profiles and a low back-pressure, dual exhaust system. The freer-flowing features thin-wall catalyst and an electronically-controlled pneumatic valve optimises exhaust flow to operating conditions. This low-speed refinement while performance and characteristic sports car at higher speeds.

The efficiency of the new TF 160 is demonstrated by the way it combines increased (top speed up from to 137mph/220km/h) with reduced CO 2 (down from 189 to 179g/km).

For the new model in the range, the TF 135, the 1.8i), a more powerful of the normal 1.8 litre engine has developed. This uses TF induction and exhaust systems high lift cams, a power increase from (118bhp, 88kW) to 136Ps 100 kW). In addition, the engine ECU has re-mapped to optimise throttle and the VVC / TF 160 gear ratios have adopted for improved in-gear

Against the clock, the TF 135 is now creditably to the former VVC model, with a top of 127mph/205km/h.

In the new TF range, the unique-in-class of a EmCVT sports auto cum ‘manual’ transmission, with shift controls, continues in the of the TF 120 Stepspeed. This retains the (118bhp, 88kW) engine, and the of either ‘normal’ or ‘sport’ automatic drive, plus a six-speed mode, controlled by twin up/down toggles on the wheel or via the centre floor

The entry-level 1.6-litre version of the MG F has popular since its launch in 2001, making up around one in of all MG F s sold, and this now has its equivalent in the new TF 115 The sweet, short … unit produces a power of 116Ps (114 bhp, with a top speed up from to 118mph/190km/h, while also a class-leading low CO 2 rating at 169gm/km.

All the transmission models benefit an improved gearshift linkage, a short-throw lever and revised linkage geometry to reduce in the shift system for enhanced selection.

SHARPER STYLE

MG Group’s Product Design Peter Stevens, is deeply in sports car design, having on every type from Elan to McLaren F1. While the essential ‘modern classic’ of the MG F . he and the design team have the MG TF a harder, more aggressive honed in the wind tunnel for stability. The new front bumper/spoiler has a sharper, more emphatic with a full-width character and a black graphic framing the air intake, with its provision for fog lamps.

The new bootlid has a top surface and an integral raised lip spoiler, stretching the visual of the car. Built into the lip is a new high-level brake lamp, fast-acting LED illumination. The tonneau finishers on each side been changed to an alloy matching the admired fuel cap.

In harmony with the new bumper, the new rear bumper has a feature line and a black surrounding the aperture for the new larger round exhaust tailpipes. As on the MG the new MG TF rear lamp units clear lenses for the direction and reverse light sections.

MG TF AND TRIM

There are four elements to MG TF colour and trim: interior hardware, interior trim and hood. Additionally, a colour hard top in black, or to match the paint colour is as a factory-fit option.
